Ideal for high temperature cutting operations in many materials such as titanium and nickel alloys, Co-Cr-Mo, stainless steels, alloy steels and cast irons. When exposed to high temperature it forms a hard aluminum oxide layer. As temperatures increase, the coating insulates the tool and rejects heat into chips: * Very tough coating that will hold up in heavy and interrupted cuts; * Ideal for smaller depths of cut and excels in high speed and dry machining applications and when machining hardened steel.
