ABSTRACT:
A tool or tool insert is formed of a silicon nitride sintered body which contains silicon nitride as well as a sintering aid and is sintered under a pressurized atmosphere. Freely grown .beta.-Si.sub.3 N.sub.4 including .beta.'-SIALON is removed from its sintering surface by steps other than grinding. A tool of a surface-coated silicon nitride sintered body is formed by coating the surface of a base material, which is formed in a manner similar to the above, with a layer of carbide of Ti or the like having a thickness of 0.1 to 10 .mu.m and/or a layer of Al.sub.2 O.sub.3 having a thickness of 0.4 to 10 .mu.m. Tools or inserts formed by a silicon nitride sintered body and the same tools provided with a surface coating have an excellent wear resistance as well as toughness and can be manufactured at a low cost since grinding is avoided.
