Abstract
A rotary cutting machine comprises a circular rotating element having a transverse axis of rotation and which is mounted to the rotary cutting machine for rotation about the axis of rotation. A plurality of cutting teeth are mounted to the circular rotating element at spaced apart locations about its circumferential periphery. The cutting teeth are reversible and removably fastened to the circular rotating element. Each cutting tooth includes opposed first and second cutting faces spaced apart by lateral surfaces extending therebetween. The first and second cutting faces define at least four of the cutting edges thereon, such that the cutting teeth are selectively mountable on the circular rotating element in any one of at least eight different positions, each of the positions providing a different one of the cutting edges in the operable cutting position.
