ABSTRACT:
There is now provided an oxide based ceramic cutting insert for chipforming machining of heat resistant alloys comprising a ceramic oxide based matrix and 5-50% by volume of homogeneously dispersed whiskers of silicon carbide. The whiskers have an average length of 4-7 .mu.m, with substantially all of the whiskers having a length less than 10 .mu.m.
