Abstract

A sintered ceramic cutter for use in machining, is crack-free in the unstressed condition and consists of alpha -alumina and 0.5-35% by weight of stabilized zirconia, having a degree of stabilization of 40% to about 100%, and contains as a stabilizer 3-9% by weight of magnesia and/or CaO. A method for producing the shaped body is disclosed.
