7/8" OD x 3/4" Shank OD x 1-7/8" LOC x 4-1/8" OAL 4-Flute Single End Cobalt High-Speed Steel (HSS) Standard Roughing End Mill, 30° Helix, Center Cut, Square End, Regular Length, TiCN Premium Grade Coating.

This 4-flute cobalt high-speed steel roughing end mill combines HSS toughness with improved hot hardness for demanding material-removal applications. The chip-breaking roughing geometry is designed for productive stock removal in slots, pockets, shoulders, and side-milling operations before finishing passes. The center-cutting geometry also supports controlled axial entry, ramping, and pocketing when appropriate for the workpiece and setup.

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