Coated 4 Flute, Medium, Long, Extra Long Length Single End End Mills, Solid Carbide USA

Coating: AlTiN (Aluminum Titanium Nitride)

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.
