what is atb blade
These blades are also known as âmulti-purposeâ blades or â4+1â blades. The intent is to make a blade which can be used for any common woodworking cut. As a combination blade, ATBR blades are a compromise, providing speed and quality at the same time. They sacrifice some of the speed of a rip cutting blade, to gain some of the smooth finish provided by a crosscut blade. This is done by using a combination of ATB (alternate top bevel) teeth and FTG (flat top grind) teeth.
