3/4" OD x 3/4" Shank OD x 4" LOC x 6-1/4" OAL 3-Flute SE Cobalt HSS Aluminum MKN Roughing End Mill 40° H CC SQ Long TiCN-PG EDP #77977

3/4" OD x 3/4" Shank OD x 4" LOC x 6-1/4" OAL 3-Flute Single End Cobalt High-Speed Steel (HSS) Aluminum MKN-Style Roughing End Mill, 40° Helix, Center Cut, Square End, Long Length, TiCN Premium Grade Coating.

This 3-flute cobalt high-speed steel roughing end mill combines HSS toughness with improved hot hardness for demanding material-removal applications. The aluminum roughing geometry is designed for productive stock removal in aluminum and other suitable non-ferrous alloys, with flute space intended to support chip evacuation. The center-cutting geometry also supports controlled axial entry, ramping, and pocketing when appropriate for the workpiece and setup. The MKN designation identifies the manufacturer-specified roughing profile for this series.

The TiCN Premium Grade coating provides a hard, low-friction surface intended to improve wear resistance in suitable rough-milling applications.
