Circular Saw - A Tradesman's Guide

These days most professionals own more than one circular Saw, and with good reason. When selecting a ability Saw, there are estimate of factors to take into consideration.

Most circular Saws use a seven inch blade, which is fine for nearly all applications. Larger models are available, but are usually not needed unless you'll be cutting posts and beams on a regular basis.

The estimate of bevel that a saw can cut is an important factor. Approximately all models can be set to cut a forty-five degree bevel, but definite saws can cut up to fifty-five degrees with ease. While it may not sound like much, the ability to cut a steeper bevel is a handy feature to have.

Take into catalogue the ease of using the saw. Each saw manufacturer uses a different guide on the cutting deck to allow you to monitor the location of your cuts. While it is strictly a matter of personal preference, being comfortable with your cutting guide is important. Likewise, ensure that you are comfortable with the methods of adjusting your saw's cutting depth and bevel amount. Some use locking levers while others use knobs. Again, it's a matter of preference, but an important one.

Laser guides are a fairly new feature ready on some models, and are especially useful when ripping boards or development long cuts on plywood. Also, many saws now have Led lights just above the blade to help out in dark places.

Two things that are often overlooked when buying a saw are power and weight. Take into catalogue the wattage and just what you'll be cutting. Harder woods like oak need more power, as does development cuts against the grain of the wood. The higher the wattage, the easier these cuts will be. If you'll be using the saw for extended periods of time, the weight is worth considering. While there are few differences from model to model, a few weigh a vital bit more than the rest.

Most circular saws come with a few accessories. Rip fences are extremely useful when development difficult long cuts, and nearly every saw comes with one. Hard plastic cases help protect your saw and are frequently included with the purchase of a saw, although some saws come with only a cloth bag or with nothing at all. Dust range bags are ready for a few models, and are useful in a fulfilled, space where dust is an issue.

With so many options available, it's easy to find the perfect saw to fit your needs. No matter which circular saw you rule on, it will likely be the most frequently used power tool you own.

Matching Circular Saw Blades to Materials

Circular Saw blades come in many separate styles to match separate applications. The material you're cutting and the type of cut will conclude the right circular Saw blade for your job. Refer to your circular saw's documentation to conclude the permissible blade size. Never use an incorrectly sized blade with your circular saw.

What's Your Saw Blade Made Of?

Steel circular saw blades are cheap. These blades are fine for soft wood or other soft materials, but will dull quickly when used with hardwood.

High Speed Steel (Hss) blades are more high-priced than tasteless steel blades. Hss circular saw blades deal with harder materials than tasteless steel and last longer.

Carbide circular saw blades have carbide cutting tips. These blades are among the most high-priced but can last up to 20 times longer than other blades.

Got Wood?

A estimate of saw blade types are right for cutting wood. Ripping saw blades (to cut with the grain) and crosscut saw blades (to cut across the grain) are two tasteless saw blades excellent for wood.

Combination blades merge ripping and crosscut features in a single blade. Composition saw blades are good for miter cuts. When looking at Composition blades, remember that a higher tooth count will consequent in a smoother cut.

Plywood blades are excellent for cutting thin sheets of wood. The high tooth count of plywood blades makes for a very plane cut.

A dado blade is used to cut exact grooves in wood. These blades, which comprise two cutting surfaces and a set of chippers, can only be used safely with bench or table saws.

Engineered To Be Perfect

Dimensional or engineered materials often need to be cut to tight tolerances. A thin kerf saw blade has a narrow profile that makes a then, exact cut.

Hard As A Rock

Abrasive saw blades are coated with ground material to cut straight through hard material. An abrasive saw blade is excellent for cutting masonry, stone or steel.

Diamonds Are Forever

Diamond coated blades are a special type of abrasive saw blade. Diamond blades are designed to cut glass, tile or ceramic materials.

general Tips on Circular Saw security and Use

When it comes to the success of your home mend and improvement project there is nothing more important than to unblemished the project with no injuries! I remind my self of the safety rules each time I use a tool, especially a power tool. That is why after 25 +/- years I have yet to hold a major injury, knock on wood. (I cut my thumb pretty bad with a utility knife one time in my youth not having employed allowable knife safety). However my appendages are all in place, I have no broken bones, no back problems or knee problems. I want the same for you.

Secondly, it is also important to use the Saw properly so that you end up with a pro seeing job!

What is a circular Saw (also known as a skill Saw)? In our example it's the kind of saw that is hand held on top of the material that is to be cut and has a circular blade. Hence the name. The area of the saw that rests on the material is called the shoe plate. The blade comes in sizes most ordinarily from 4" to 8". For general cutting purposes on home projects a size 7 ¼" is most common. If man asks you what size saw you have, the allowable write back is to tell them the blade size. Blades also come with varying numbers of teeth. The whole of teeth on the blade should be right for the material and the direction of the cut. When cutting along the distance of the wood (with the grain, called a rip cut) use fewer teeth. When cutting across the wood (across the grain, called a cross cut) use more teeth. If the wood is harder, use more teeth. Carbide tipped blades are better. When properly installed for wood cutting, the teeth on the front of the blade should be pointing up. For cutting other things, such as vinyl siding, the blade can be put on "backwards". All the time disconnect the power cord when changing blades. Don't use an overly dull blade. Blades can be changed easily: First, it helps if you set the blade depth to shallow. Second, find the blade lock on the surface of the saw. It's kind of like a metal button that you push. Then find a wrench that fit's the retaining bolt in the center of the blade. When you buy circular saw blades make sure the arbor (the hole in the center of the blade) is the right fit. Next, push down on the blade lock and turn the blade until you feel it lock. Now you can unscrew the retaining bolt counter clockwise. Once the bolt is removed, lift the blade guard to take off the old blade. Setup the new blade using reverse procedure.

Most circular saws will typically have 2 adjustments. One is the bevel adjustment. This is the one that tips the saw blade from side to side. This in turn causes the saw to cut at an angle. Use at 0 degrees for right cuts. The other is the blade depth. This is the one that allows the blade and the motor to slide up and down in relation to the shoe plate. This causes the blade to cut deeper or shallower into the material. Regularly these adjustments are held in place with nut and bolt type fasteners. The nuts will come in varying shapes and sizes. Be sure they are tight before using the saw. Also don't forget to unplug the saw before development adjustments.

The on-off switch is a trigger/toggle type which may or may not have a safety latch. Issue the safety (if it has one) and "pull the trigger" to actuate the blade. Don't forget to Issue the trigger when you are closed development the cut!

As far as development a cut goes there are a few things I like to remember before I do: Cut outdoors if you can. If you cut with the wind at your back, it will blow the sawdust away from you. Have good lighting. Wear eye and ear protection. Wear shoes and socks. Avoid loose clothing and any other object that can come close to the blade. Avoid distractions that can suddenly cause you to loose focus. Adjust the saw for angle and depth. Make sure the material is garage and won't move colse to as this can effect in injury and/or a poor cut. In the absence of a helper, I like to use clamps when working from a saw horse. If you are working from a pile you can sometimes put foot or knee pressure on the material to keep it steady. Use common sense though and don't try anything that doesn't seem right. Remember: sawdust on plywood can make it glossy when walked on. Pay attentiveness to what is under the material you are cutting. anything comes in sense with the material along the line of your cut will be affected by the blade in the same way the material is. This includes fingers! Put something under the material to avoid unwanted sense with the blade. Shade your eyes from attractive sunlight. Make sure the mark you are cutting along is clearly visible. Cut with the back of the material (the side that won't show when installed) on top. This will insure that the side that shows will have a nice clean cut with no "feathers". Make sure the power chord of the saw is trailing behind the saw and can't be cut accidentally. Adjusting the blade depth to approx. 1/8" below the material helps with avoiding unwanted outcomes.

(Warning! Kickback is when the back of the blade binds and causes the saw to suddenly jump violently away from the material, and possibly out of your hand, causing potential injury, damage to the material and damage to the saw. One way to avoid this is to go slow with your cut. If you feel resistance and observation the motor wind down, kickback could be imminent! Stop send motion with your saw. Issue the trigger and hold the saw steadily in place until the blade comes to a unblemished stop. This type of kickback Regularly occurs when development a rip cut and is caused by the wood having natural tension in it, pinching the back of the blade. To remedy this problem, place a wedge in the curf (the measure of the material that is taken out by the blade) in between the two sides of the cut. Other ways kickback can occur are if you or the material or the saw gets bumped or are otherwise disturbed. This can cause the back of the blade to be moved to the side causing it to bind. an additional one way is if you let go of the saw while it is still in the material and the blade is still moving. Still an additional one way is if you try to cut a radius. Circular blades are intended for right cuts, right blades, like jigsaw blades, are intended for circular cuts. If you use it for anything else you are taking your chances. Don't try to cut the wood in between the sawhorses, All the time on the outside. More specifically, never have the material supported on both sides. hold the long side of the board and have the short side be free of contact. Kickback can also occur if the blade has sense when you "pull the trigger". But mostly, avoid kickback by paying attentiveness to how much pressure is on the back of the blade.)

Now you are ready to make a cut. I like to start with just the front end of the shoe plate resting comfortably on the material. Make sure the blade is not touching the material when you "pull the trigger". Set the blade in line with the cut line so that it is on the side of the line that is the "waist" side. Make a few small "test" cuts attractive the blade closer to the line each time. When you desist the cut, the mark should still be visible but get as close to it as you can. Remember: you can All the time take more off the board if it is too long but you can't put more on if it is too short! Make sure the power chord can move freely. Try to relax as you make the cut. Be gentile with your motions. If you fight the saw, the saw will probably win. Cutting moderately will make a best cut. Focus your vision on the blade, not on the wood, from the cope side of the saw. Make sure the shoe plate is resting wholly and flatly on the material. Less side to side motion makes a straighter cut. The blade can be maneuvered to stay on the line but watch for kickback. I like to push the saw with my body rather that with my arm. Cut past the end of the cut. To avoid the "chink" that can occur when the waist side falls off, place an object that is about 1/4" to 1/2" below the waist piece so that it doesn't fall too far.

This is in no way intended to be an exhaustive essay. It is just a few notions I had on a Sunday afternoon while mental about my circular saw. Use your own good judgment. Leave a commentary and Happy Sawing!

You Can Build Your Own Circular Saw Table

Since circular Saws are the movable version of a table Saw, they are not meant to be fixed to a table. However, the portability can be a disadvantage if you are trying to make precision cuts such as miters or other angles. To help you make more accurate cuts, you can build a circular Saw table in your own shop.

Step 1

Gather your materials which include a 3/4" thick medium density overlay (Mdo) in a 36"X16" sheet, a 36"X8 1/2" piece, a 36"X1" piece, and two 36"X1 1/2 " pieces, a pencil, ruler, jigsaw, eight strips of 1"X2" wood, nails, hammer, drill, 1/4" and 1/2" drill bits, screws, circular saw, 1/2" dowel, speed square, and 1/4" carriage bolt.

Step 2

Mark the median 3/4" in from the edge on the long side of the 36"X16" Mdo.

Step 3

Using the ruler, mark a radius from this median on that front edge. Next, draw a right line 10 inches from and parallel to the back edge.

Step 4

To cut out the table that you just marked, use the jigsaw to cut down the 10" line, colse to the radius, and down the 10" line on the other side. You now have the shape of the table.

Step 5

Flipping the table to its back, nail six strips of the 1"X2" wood to all of the right edges as the reserve for the table.

Step 6

Go back to the customary median mark on the topside and drill a 1/2" hole in which the dowel will be settled to serve as the pivot for the arm.

Step 7

Down from the hole on this topside, attach two more 1"X2" strips 10 inches long to serve as the fence for the guide.

Step 8

Take the two pieces of Mdo that are 36"X1 1/2" and cut a 45-degree angle off of each end. With the angles facing inward, screw these two pieces onto the ends of the 36"X8 1/2" piece of Mdo. This makes the carriage with spacers.

Step 9

Screw the 36"X1 1/2" Mdo to the edge of the 36"X4" Mdo at a 90-degree angle to generate a guide lip. Attach this assembly to the reserve blocks of the carriage with screws. To make the opposite side of the guide, screw the 36"X2" Mdo to the other side of the carriage. The circular saw's blade should pass through the gap as it follows the guide lip, but you may need to adjust the gap width for your single saw.

Step 10

Now, with the saw against the guide lip and the blade in the gap, fix an opposite lip to keep the saw right as it passing through the carriage by screwing on a 36"X1" strip of Mdo on the opposite side.

Step 11

Flip this carriage over and portion down 7 inches from the top edge. Mark the median of the width at this point and drill a 1/2" hole for the dowel.

Step 12

Removing the upper part of the carriage, place the base under the table and tap the 1/2" dowel through both the table and carriage, not allowing the dowel to stick out past the carriage blocks. Then, reattach the upper part of the carriage.

Step 13

Slide the carriage arm as far right as possible. Putting the speed quadrilateral between the arm and the fence at a 45-degree angle, drill a 1/4" hole through the upper assembly and tabletop to obtain the arm with a carriage bolt. Do the same at the 90-degree and 45-degree left angle to make repeated angle cuts.

Your circular saw table is ready to use. Place the wood to be cut against the fence. Line up the arm to the angle that you want. Put the circular saw in the guide arm with a depth set so that you will only cut 1/8" into the table. Make your cut. You can now make accurate angle cuts time after time with your circular saw table.

Using a Cordless Battery Powered Circular Saw

A cordless battery powered circular Saw is one tool that I will all the time keep in my possession. When they first came out a lot of experts were skeptical about how much power they would have. Well they aren't as grand as a corded circular Saw but they run a close second.
 
Cordless battery powered circular saws are designed to deal with 2x stock. All the saws come with carbide tipped blades. This is because you need a sharper, best cutting blade with this tool because you wouldn't have the sustain power to force the blade through your cut if the blade was dull.

Most manufacturers sell these saws in kits with other cordless battery powered tools, usally a cordless battery power drill. Skill is one constructor who does not sell this tool by itself. So check nearby and see if any person does sell it by itself and also check if it comes with a extra battery. I advise getting a extra battery so that while you are working you can have a battery ready for when the battery in the saw starts to lose power. Most of these batteries recharge themselves in about a half hour.

Safety is not a big concern because this tool is lightweight and easy to handle. Just be faithful to all the time remember that when the battery is in it's just like having a corded tool plugged in.

On a scale of 1 to 10 on the point of having this tool in your shop, I give it a 10. This tool is great for many projects and so easy to deal with it is a must have tool for everybody.

selecting a Circular Saw

I have spent thirty plus years doing construction and renovations. While that time, we have used and even abused, most brands, styles and sizes of hand held circular Saws. (I personally was never complex in the abuse part). Having employees, means having abuse. It's surprising what some habitancy will do with someone else's equipment.

The first circular Saw I ever purchased was a Skill 7 1/4" Saw, with 2 1/4 H.P. I was eighteen at the time, and had just decided I was going to be a contractor, when I grew up. (if I grew up). The unit I purchased was not my first choice, as it seemed kind of costly at the time. The owner of the lumber yard I was dealing with, also happened to own a large construction company. When he Saw me carrying the saw I chose up to the counter, he inquired how long I intended on being in business.

Me being the cocky sort, said something along the lines of forever. (Failing didn't seem even remotely possible, at the time). He said if that's the case, I'd best consider my selection of saws. My selection was apparently a poor one. He steered me to the Skill saw I ended up with. Now, thirty years later, the only repairs ever needed on that saw has been two cords, and a set of brushes. The cords don't stand up well to a saw blade.

That singular saw has a set of bearings in it that will keep the blade spinning for about twenty seconds after letting go of the switch. In the right hands, it will cut a line level and square. And believe me when I say it's seen some serious use, in many separate hands.

I've since bought about every brand and size since then, and have never been as satisfied as I was with that one. Even the 8 1/4" saw, supposedly the same saw but larger, and about fifteen years newer, hasn't impressed me as much as the first one. Cutting a level line with that one has never come to be second nature like the first. (In all fairness, I personally haven't done the amount of actual corporeal work as I did in those early years, thank God). I am still able to cut a very level cut with the traditional one though.

That saw wasn't a worm drive saw. That singular style of saw seems to lend themselves to cutting a level line rather easily, and have plentifulness of power. This style is the first selection of many expert contractors, due to there ruggedness. I have, and use this type of saw as well, but I limit it's use to very abusive situations. They are made to take it.

I've bought saws from manufacturers, that were reputed to be very high quality, and were made by the very same habitancy who made some serious equipment, that performed extremely well. After using them for a combine weeks, I just gave them away. Some saws are not designed for the user, but for the ease of manufacture. No thank you very much!

Sometimes I swear that the engineers have never held, used, or researched the very tool they were designing! And the surprising part is they well make it to the market. You'd think that somewhere along the line, someone would have said, "this is a piece of junk", and sent the engineer back to school, or at the very least, back to the drawing board. But no!

One of the newer brands on the shop in the Usa, is Festool. While it has it's limitations for construction, for cabinet manufacture it's great. With the extendable, non slip, track system, cabinet ability cuts are simple. Even mitering cabinet sides on a job site are no problem. And with the dust variety principles hooked up to it, it's hard to beat. I did notice new users have a bit of trouble getting used to it having a retractable blade system. This lead them to well having a kick back, and cutting the aluminum guide. This seems especially true for left handed users. And for those with two left hands, forget it.

Bottom line in choosing a saw is first deciding what type of work it will be used for most often. If you're going to be cutting 2" x 4" lumber, forget the Festool. It's just not worth destroying a good saw for that. Also, stay away from the .99 saws, unless your need a curved cut, because level is out of the question. Anytime you can watch the shaft slide in and out While a cut, you have a problem.

Look for a saw with a 15 amp motor, and try to move the shaft in and out prior to buying it. (Unplugged of course). If possible, test it out. Some saws go out of there way to blow the saw dust in your eyes. Having a shoe that won't bend or break is a big plus, and a notch where the blade will well cut is pretty handy. (Although, I rarely use them. I like to see where I'm cutting, so I look at the blade). And By All Means, use security glasses.

Following these basic guidelines will get you a saw that you'll be able to count on for years to come.

The Circular Saw

There are many dissimilar varieties of the circular Saw. This Saw is ordinarily classified by its circular blade, which lumps it in a kind with a variety of Saws that use that blade. Using a metal disc with Saw teeth, the blade spins colse to and helps make an accurate cut. There are a variety of circular saws from ones that are mounted to other hand held options.

One of the types of circular saws is the miter saw. This saw is known for its small cuts on an angle. The circular blade comes down on a piece of wood that is located at a set angle. Using this type of circular saw is perfect for doing molding colse to the house, development photo frames, or other cuts that wish an attentiveness to detail.

Another circular saw is the radial arm saw. This saw has a sliding horizontal arm that allows you to move it straight through a cut of wood. This saw is ordinarily used to make long cuts accurately. As you place the wood on the table, and push the handle, the saw will cut straight through the board on the same line the entire time.

The table saw, which also uses a circular blade, was created more for accuracy. These saws ordinarily have a table that stabilizes them to make an accurate cut. Some table saws are able to be mounted on a table so you can move them around. The table saw is used most often by a undertaker of a package deal for a large job. There are discrete types of these saws which comprise the bench top table saw, the contractor's saw, and the cabinet saw.

Another circular saw is the panel saw. This saw cuts sheets of wood, metal, aluminum, plastic, or anyone else it may be into sized portions. You will ordinarily find these saws in a shop that specializes in some type of major construction such as cabinetry construction.

A more unique circular saw is the string trimmer or weed whacker. The weed whacker uses a dissimilar type of circular blade that has a string. As the motor moves, the string goes colse to in a circular request for retrial and cuts grass and weeds. This makes it easy to trim portions of your lawn or asset that your lawn mower may not be able to get to.

The cold saw is other type of circular saw. These saws are just what they say. They use a replacement of heat to make it easier to cut anyone it is they are cutting. Generally, a cold saw is used for sheet metal roofing. There are discrete types of blades depending on what you select to cut with your cold saw.

The circular saw has a broad definition, and includes a lot of saws that habitancy may not have even realized were saws. With a circular blade that makes cutting a product easier and more accurate, the circular saw has increased accuracy for these types of wood projects. anyone type of wood project you are about to take part in, there is probably a circular saw that will work for you.

Circular Saw protection

I would say that aside from possibly your drill-driver, the circular Saw is one of the handyman's most oftentimes used tools. But as useful as this tool is, it can also be very dangerous (duh). A blade spinning fast sufficient to slice through wood like butter is no toy to be played with. One thing about these Saws is that they have this annoying guard that keeps shootin' back over the blade every time you pull it out of the work piece.

So although dangerous, many woodworkers tie the guard up so that it's constantly in the "up" position. This also means that when you place it down periodically in in the middle of use the blade will make direct caress with the outside you place it on. This is not good for the blade - not to mention what would happen if someone were to accidentally trip over it and trigger the switch! -Talk about a saw that's got Legs! (The solution for this is to park your saw upside-down or blade-up.)

So as is often the case, you have to reduce a slice of your protection for a scoop of user-friendliness. I personally prefer to take this risk over dealing with that nagging guard. Having said that however, a friend of mine recently had an urgency while using a circular saw and it was a good reminder that you can't ever "let your guard down" if you know what I mean. He was a bit shaken but ok.

The 2 of us were working up on a rooftop laying roofing panels and it just so happened that my friend was scared of heights. So he had to sit and work cuz he couldn't bear to stand and be field to one of his worst nightmares. Anyway, sitting while using a circular saw is not advised - for safe bet reasons. Your arms don't have much reach which means your legs come to be your work bench - bad, Bad idea!

He was lucky as he walked away with only a small nick near his right knee. I don't even want to fantasize what Could have happened. Being comfortable and procure in your work environment is an foremost point as this not being the case played a part in causing the accident. Good luck with your circular saw use and remember to pay attentiveness to the points mentioned above. In conclusion, make an educated decision on either you'll use your saw with or without your guard - the manufacturers put the guard there for a reason.

Three Kinds of Circular Saws For Three distinct Jobs

While there are many types and sizes of circular Saws on the market, I would like to discuss what I believe to be the three most prominent categories. They are: plunge Saws with guide rails, worm drive or hypoid Saws for building use and standard-drive circular saws convenient for both home and building use. Before I delve into all of that, however, I'd like to take a quick look at the basics.

A circular saw allows you to take a relatively small tool to a large work piece and cut it without too much back-breaking labor. In the past, the price for this convenience was inaccuracy because there was no truly easy way to force a circular saw to cut right along a pencil line. For rough building work like roofing and decking, this was no problem. For fine woodworking, however, the circular saw was not the tool of choice. Most woodworkers rely on the table saw to get the long, right cuts they need and for good reason. The fence on a table saw gives the constant reference point needed for right cuts.

Sometimes, however, using a table saw to trim the top of a huge consulation table, for instance, turns out to be an impossible task, especially when trying to trim off the ends at 90 degrees to the sides. That's when a very carefully planned arrival using a circular saw seems to deliver the best final result. I would draw a pencil line using a long straightedge exactly where I wanted the trim cut to go. I would then carefully portion the length in the middle of the inside (or outside) of the saw blade and the edge of the foot plate of the saw. The next step would be a second pencil line, parallel to the first one and separated from it by the length I measured in the middle of the inside (or outside) of the saw blade and the edge of the foot plate. I would uncover an truly right board (ripped right on the table saw, if necessary) and clamp this across the table top as a guide along the second pencil line. Then, I could make a pretty right cut along the first pencil line. I would then repeat this for the other end of the table top.

In the past few years, this process has become a whole lot easier. There are now some makes and models of plunge saws that run along metal guide rails, cutting right next to the edge of the rail without cutting into the rail itself. The guide rails don't even need to be clamped to the exterior being cut because they have material underneath that keeps them from sliding around. If you feel more comfortable clamping down the guide rail, this can be done, as well. It's a uncomplicated matter to lay the guide with its edge along the cut line and then to take the saw and run it down the rail, cutting right next to the lip of the rail.

Because these saws are plunge-type saws, you can begin and/or end a cut in the middle of a sheet of plywood. You could cut out a window or door opening, for instance and have it come out clean and quadrilateral every time. The best thing about using these track saws is the reliance they give you: You Know you can do a exquisite job, quickly, accurately, over and over again.

Another kind of circular saw I've used a lot over the years, mostly for construction, is the worm drive saw pioneered by Skil. A framing carpenter needs to be able to cut a lot of lumber all day long. While accuracy is all the time desirable, it is not as vital to the framer as it would be to a terminate carpenter or cabinet maker. Speed is the thing that the framer wants on his side and he (or she) does not want to be saddled with a saw that can't cut the mustard, so to speak. He doesn't want his circular saw to bog down in the middle of cutting a 2 x10 joist or have the sole plate hang up every time it goes across the edge of someone else board. He does not want to have the saw blade slipping nearby the saw arbor. What he wants is clean, fast precise cuts: In short, power.

A worm drive saw delivers the constant power he needs because there is no slack or play everywhere in the middle of the remarkable motor and the saw teeth that are doing the cutting. The worm gear cuts down a bit on saw blade Rpm but trades this off for torque. It is torque, more than speed, that powers a saw blade through thick, wet wood. A diamond-shaped arbor makes it virtually impossible for the blade with a matching diamond-shaped hole to rotate nearby the arbor. Keeping the number of saw teeth down to 18-24 teeth on a 7 1/4" saw blade also helps. The only qoute with early Skil worm drive saws was the weight with those large motors and all that gearing. The clarification was to use magnesium instead steel in the building of the saw wherever possible. The contemporary magnesium worm drive saws weigh only about 14 to 15 pounds which is more than a acceptable circular saw but manageable in the strong hands of a muscular framer.

The final type included the kind of saw that most habitancy think of as a circular saw. It is lighter than the worm drive saws and, for most uses, it's plenty remarkable enough. Some of these saws are now also be made out of magnesium parts and weigh just over 10 Lbs. This makes them easy to use by the midpoint do-it-yourselfer. Did I mention that they are a lot less high-priced than the other types?

Be very truthful Using Circular Saws

Most citizen unmistakably don't care about how to tips on power tool safety, but I'm going to tell you a story and see if that makes a difference. About 20 years ago I remembered other carpenter, who was working on the roof, installing fascia board.

He had been installing fascia board longer than I had been alive. He often shared this data with me and called me a young whippersnapper. I was taking a break one day, while he was working on the roof as I watched him cut his leg with an galvanic power Saw.

You're probably wondering, did he have the guard wedged up, on his Saw or was it down, where it should have been. It was wedged up, like every other carpenter on the job, at that time. It wasn't bad enough, that he cut his leg with the power Saw, but when he pulled the saw out of his leg, he fainted.

Did I mention that this guy was working on the roof? Did I also mention that this man was working on a roof that was sitting directly on top of a two-story home? If I didn't, you probably have a better photograph in your mind, because this man fainted and fell off the roof.

He lived, but he didn't come back to work for quite some time. Years later I talked to the man about his emergency and he couldn't believe that it happened to him. His thinking inspired me to write this article. He didn't think it could happen to him and I didn't think that I would ever cut my thumb off, but I did.

The next time that you're using a circular saw in an unsafe manner, maybe you will think about the story you just read and perceive that this kind of stuff could happen to you.

Buying a Circular Saw

Are you seeing for a new circular Saw? I am. I have an old, cheap one that I bought at Home Depot about 10 years ago that has just about had it with my torture. So now I'm seeing at my options to buy a new circular Saw. Do I go cordless? How much will I use it? What do I need it for? How much power do I unquestionably need in my circular Saw?

I spoke to my brother Joe about it. He's a contractor in Buffalo, New York and a huge fan of DeWalt tools. He always goes for top of the line quality in his tools. Joe said that cordless circular Saws are good for when you are working up on a roof or at places where there is slight or no power access. As far as strength, Joey says that the newer cordless tools have roughly the power of corded tools. Almost, but not quite and unquestionably not if you are using them to cut framing pieces all day long. Joe has both a wormdrive and a quarterly circular saw. He pulls out his Skil Hd77M wormdrive circular saw when he needs to get straight through the big stuff. But when he will be cutting 2x4's all day, he uses the lighter weight DeWalt 368K. And, for cutting up on the roof, he uses his DeWalt cordless Dc300K with a Nano battery. Joe said he got into the Nano technology because it gets damn cold in Buffalo and he wants the reliability of Lithium Ion batteries, which will accomplish just as well in cold temperatures. And the nicest thing about them is that the DeWalt Nano batteries are backwards compatible with all his DeWalt cordless tools.

Hmmm. But what kind of circular saw do I want? While I am not a contractor, I am an avid Do-It-Yourselfer who has a sweet job as the editor of a tool blog. Yup, I get a great allowance on the high quality tools that are sold at the Toolking Superstore and you betcha, I've been taking advantage of that! (shameless plug ;0) Seriously though, even if I didn't get the discount, ToolKing has the bottom prices, especially if you go for the reconditioned versions (believe me, I've checked around). ToolKing's hidden (for all you e-commerce wannabe's) is that they buy in very large quantities from clubs like DeWalt and Makita and that leverage gets them a best price deal, which they then pass on to their customer, aka: You.

Anyhoo ~ back to my circular saw purchase.

Corded versus Cordless

I'm debating whether to go with a cordless or corded circular saw. My husband and I bought the crappiest, smallest house in our neighborhood so we are in the middle of remodeling pretty much our entire home. Because we both work full-time jobs, we remodel in spurts. Our circular saw just crapped out on us on the last project. We were framing an outdoor patio area with 6x6's to lay pavers. Poop, went our circular saw, it had had enough. Like I said earlier, it was old, cheap and from Home Depot. Okay, maybe we were pushing it a bit on the 6x6's but who doesn't push their tools to the limit of what they are supposed to be used for? Especially homeowners, who typically don't have the large choice of tools that a contractor would have, or don't always have the 'right tool' for the job (the right tool for this job would have been a circular saw with a Prazi beamcutter attachment).

After a bit of debate, we decided to go with a corded circular saw or a Lithium Ion battery powered circular saw because we often go some weeks or months in the middle of projects. When we need to use the circular saw, we want to use it now. Lithium Ion batteries have a long shelf life, which means they will stay expensed even if they sit on the shelf in your carport (in the cold) for some weeks. They are also very lightweight. So if we go cordless, we will opt for the Lithium Ion battery powered circular saw. Makita makes a nice LiIon circular saw and you can get one with the buy of their Lxt700 18v LiIon combo kit. The LiIon circular saw included in the Lxt700 kit has a 6-1/2 inch saw blade though, not a 7-1/4, which is what we are seeing for.

I went into the Toolking store. The ToolKing store has a great setup, Doug and the guys have redesigned the entire layout so now you can touch and hold all the tools. I love that! You can unquestionably get a feel for which one you like best because when it comes down to the options, there are a lot of high quality tools ready but which one feels best in Your hands? Most of the contractor grade circular saws have a 15 amp, powerful motor, magnesium housing (for lightweight and strength), at least a 45 degree beveling capacity and exquisite security features. I personally need to pick up each one as if I'm using it, and check the position of the handles for relax and how good my line of sight will be to the blade.

These are the circular saws that I compared:

1. I picked up the DeWalt Dw368K. Lightweight at 9.5 lbs, it is durable adequate to withstand a 1-story drop. The DeWalt Dw368K also has a beveling capacity of 56 degrees.

2. The Makita 5007Fak is a bit heavier at 11.1 lbs but has this cool onboard Led light and a ruler on the foot plate. How many times are you working in a room with the light at your back?

3. I'm a big fan of the Bosch business because of all that I've learned about their power tool recycling schedule and other pro-active enviromental projects. The very nice feature of the Bosch Cs20 (10.3 lbs) saw is their Direct join together Cord administration System. The Bosch Cs20 doesn't have a cord, you plug your power cord into it. So you never have to deal with replacing the cord or tossing your tool out because the cord has split. The Bosch Cs20 also has a blower in the front that blows the sawdust out of your way as you cut so you can see where you are cutting. The Bosch Cs20 also bevels at 56 degrees.

4. Then there was the Porter-Cable 324Mag. Super lightweight, the 324Mag weighs 9.6lbs. Out of the circular saws I looked at, only the Porter Cable brand had an exhaust port for a vacuum attachment, a nice feature for working in the carport or house.

5. Milwaukee makes the 6394-21 Tilt-lok. It is the most high-priced of the bunch at 5 but features an exclusive Tilt-Lok handle that is probably more adjustable than I am. The Tilt-Lok on the Milwaukee 6294-21 adjust to 8 dissimilar locking positions, production it easier for working on angles and overhead. The Milwaukee circular saw also has a 10 foot, Quik-Lok cord for easy cord change and with a 3-horsepower motor, works as hard as my Polish carpenter father.

A good circular saw should have adequate power to cut straight through wet wood without slowing down or perilous kickback. A good circular saw should also be lightweight and durable because you inadvertently will drop it on the ground. You should choose a circular saw based on balance, maneuverability and how it feels when you hold it. Good luck!

separate Types of Circular Saws

There are discrete types of circular saw available on the store today. Generally, these saws are classified on the basis of their circular blades. This type of saw has metal disc having saw teeth and blade spinning around which helps to make exact cuts.

Circular Saws Reviews


1. Miter saw: This one is especially used to make small cuts at separate angles. With this say, circular blades come down on a wooden piece settled at an angle. You can use miter saw if you want to do molding around your house, to make photo frames and for all other cuts which require special attention.

2. Radial saw: This one has sliding arm settled horizontally which allows users to move through wood cuts. Normally, radial saw is used for development long cuts accurate. As you keep wood on the table and press the handle of the saw, it will cut along the board along same line.

3. Table saw: These also have circular blades and offer more accuracy than other saws. The table saw has a table which stabilizes them for development exact cuts. Generally, contractors use them for performing large jobs. Some of the table saws are bench-top table saw, cabinet and contractors saw.

4. Panel saw: This is used for cutting wooden, aluminum, metal and plastic sheets in sized portions.

5. String trimmer: This is also called a weed whacker. It uses separate circular blades having a string. As the motor moves, the string also moves in circular motions, cutting the weeds and grass. Like this, you can de facto trim the lawn of your home.

6. Cold saw: These make use of heat exchange to cut things in an easier manner. Generally, cold saws are used for make metal roofing out of sheets.
