Circular Blades Selector
Solid Material Chart These charts are used to get the correct tooth and pitch for a circular blade. Determine the blade diameter for your saw, typically specified in the instruction manual. Then reference the size of material to be cut to determine the appropriate blade tooth and pitch. For example, if your blade diameter is 285 mm (with kerf of 2, body of 1.7 and bore of 32) and you are cutting 60-80 mm solid round material the result is a recommended blade tooth of 60 and a 14.92 mm pitch.

Tube Material Chart For example to get optimal performance, if your blade diameter is 285mm (with kerf of 2) and you are cutting a tube with wall thickness of 12-18mm the result is a recommended blade tooth of 72 and a 12.43mm pitch.
