ULTRA High Performance 1/4" Four-Flute TiALN End Mill with .015" Corner Radius

This Canadian-made Skookum End Mill combines a .015" corner radius with advanced variable-pitch geometry and extra-fine sub-micro-grain carbide. Its ULTRA High Performance construction provides exceptional strength, stability and wear resistance for demanding profiling, finishing and production machining.

Maximum Strength and Chatter Resistance

The .015" corner radius reinforces the cutting edges to help reduce corner chipping and extend tool life. Its variable-pitch geometry disrupts harmonic vibration for improved stability and surface finish, while the TiALN coating protects against heat and abrasion during demanding machining of steels, stainless steels and cast iron.
