Common Types of Circular Saws

A portable circular saw or cordless circular saw has become the most frequently used cutting tool for do-it-yourselfers. With the right set of blades, you can use a circular saw to cut wood, metal , plaster, concrete, or other masonry materials. An adjustable base plate lets you set the blade depth for your work piece, and it also pivots from side to side for bevel cuts.

Most professional carpenters use a standard drive  7 1/4″ blade circular saw. The model has a sawdust-release pipe that connects to a collection bag. This saw also comes in a worm-drive model. Some carpenters prefer the worm-drive saw for heavy-duty cutting. Worm-drive saws offer more torque at any given speed. As a result, they are less likely to slow, bind, or kick back when sujected to a heavy load. 

The 6 1/2″ blade  circular saw is both lightweight and more versatile than its bigger brother but it is also less powerful and is limited when cutting bevel cuts or material that is thicker than 2x stock.  

The 4 3/8″ blade trim saw is well balanced and lightweight for easy handling. It has a high power to weight ratio or 7.8 Amps and 11,000 RPMs. With the proper diamond blade, this saw can even dry cut stone and masonry.

Cordless Circular Saws have become more powerful than anyone could have anticipated. The Milwaukee 0740-22 28 V Metal Cutting Saw boasts 3200 RPMs and can cut a 2″ galvanized pipe  in a single pass. Nothing can top the performance of this tool in terms of cutting speed or overall run time. milwaukee-0740-201

To get full use from your circular saw, you’ll need an assortment of blades designed for specific cutting tasks. Your collection should include at least one general purpose combination blade with carbide teeth. In addition to cutting wood and sheet material, you can also use a circular saw to cut masonry and thin metal with the appropriate abrasive blade.  Get the most out of your saw by inspecting your blade regularly and changing it as needed. You know how difficult it is to use a dull knife in the kitchen, so don’t forget about your circular saw blade! Also, because circular saw blades cut in an upward direction, the top face of the work piece may splinter. To protect the finish side of the work piece, mark measurements on the back side and place the good side down for cutting.
