About Tooth Geometry to Improve Cutting Finish

Different tooth geometry allows the blade to improve the cutting finish second to the material being work. These are the general rules of thumb.

The flat tooth (Fig.7) is used on multirip saw blades, saw blades for portable machines and universal saw blades.

The alternate top bevel (ATB) tooth (Fig.8) produces a fine cut, and is used on blades for crosscutting wood.

The "triple chip" tooth (TCG) (Fig.9) is used on sawblades for cutting wood composite materials, aluminum and other plastic materials.

The "conical tooth/alternate top bevel (ATB)" (Fig. 10) is used on scoring blades for cutting wood composite materials.
