ABSTRACT:
A cutting tooth element for a cutting blade. The cutting tooth element has a body. The body has a forward surface, a rearward surface and a peripheral edge surface that extends from the forward surface to the rearward surface. The peripheral edge surface has a constant width that is equal to the width at the bottom of the groove that is to be cut. The body of each cutting tooth has a thickened area between its forward surface and rearward surface. The thickened area has a maximum width equal to the width at the top of the groove that is to be cut. The body has sloped side surfaces that extend from the thickened area to the forward surface, rearward surface and the peripheral edge surface. The resulting shape of the cutting tooth causes the cutting tooth to retain its cutting profile as it wears.
