Rockwell circular saw blades

Rockwell circular saw blades

Saw diameters and bore sizes.
Find the right saw blade fitting to your Rockwell circular saw machine.

Whatever machinery you have, mount a compatible blade measuring the full size. Substituting a close enough undersized diameter may be possible, but not ideal.

Always work with sharp tools for the best result and safety. Wear safety glasses, work gloves and ear protection if possible, when you work with machines.

I use my circular saw more than any other tool in my tool arsenal. It cuts, rips, miters and works wonders on all sheet goods. So when I had the chance to review the Rockwell 4-1/2 - Inch Compact Circular Saw, I got excited - and got out a bunch of stuff to cut. It does almost all the same stuff my other circular saw does ...

Rockwell circular saw


Circular saw blades have different sizes from a few inches to several feet across. Diameter is the span from one edge of the circle to the other measured along a center line. The radius is half that; it is the span from the center to the edge. A saw doesn't have the capacity to cut that deep, though. Maximum depth of cut is less than the radius. It cuts no deeper than 1/3 of its diameter. A 10" saw cuts about 3" deep at maximum capacity, and usually less. A big blade has greater cutting depth. Not only can a larger blade cut deeper, it also has a larger circumference, or the measurement around the rim. A longer cutting length around the circumference makes space for more tips overall. For this reason, bigger blades have longer endurance. Small blades have less circumference circling the rim, which explains how fast they get used up. A big one might last the equivalent of two smaller ones. However, large sizes won't necessarily allow faster feed; coarseness determines that.
