ABSTRACT:
For dividing a chunk of material which comprises areas tending to deform as well as rigid areas, a cutter with a spiral cutting edge is provided. The cutting edge has two sections of which the first in the direction of rotation, is unserrated and undergoes a relatively rapid increase of radius. The second section in the direction of rotation is serrated and follows a minimal increase of radius. With a cutter thus designed, material can be cut smoothly in the region of its deformable portion and can be sawed just as smoothly in the region of its rigid portion.
