Abstract
A cutting tool for use in applications wherein a kerf is formed during the cutting operation. The cutting tooth is formed on the cutting tool including a rearwardly angled inner relief surface against which the material being cut is impacted. A secondary surface intersects the inner relief surface and extends forwardly of the point of intersection at an angle relative to the direction of cut that is oppositely directed but generally equal to the inner relief surface. The force of the material being cut that is deflected onto the secondary surface is outwardly directed and counterbalances the inwardly directed force imparted onto the inner relief surface.
