Abstract
A composition for a ceramic cutting tool which enjoys long tool life at high speed machining of ferrous alloys. The composition consists essentially of 60-80% alpha aluminum oxide (Al.sub.2 O.sub.3) having a hexagonal crystal structure and the remainder of titanium carbonitride (TiCN). The titanium carbonitride has a mixture of 30-70% titanium carbide and the remainder titanium nitride. The mixture is compacted and hot pressed, sintered or pressure sintered to form the tool.
