Diamond Blades for Circular Saws Buyer's Guide

Teeth

Usually, a blade with fewer teeth cuts faster than those with a high tooth count. For woodcutting, our wood team suggests you go for blades with fewer teeth to minimize waste and prevent it from binding during cutting.

Kerf

Kerfs impact the quality of the finish. For circular saws, the blades need to be thin to reduce the strain put on the saw instead of being wide. It translates to more convenience when cutting. 

Quality and Durability

The quality of the blade determines its durability. The most suitable diamond blades for circular saws are made from high-carbon steel or high-speed steel materials, with some coating to prevent rust [1]. Both materials offer incredible strength and robustness.
