Diamond Blades for Circular Saws Buyer's Guide
Teeth
In my experience, a blade with fewer teeth typically cuts faster than those with a higher tooth count. When it comes to woodcutting, I always recommend opting for blades with fewer teeth. This not only minimizes waste but also helps prevent the blade from binding during the cutting process.
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.
