3/8" OD x 3/8" Shank OD x 1-1/2" LOC x 3-1/4" OAL 4-Flute Single End Cobalt High-Speed Steel (HSS) Standard Roughing End Mill, 30° Helix, Center Cut, Square End, Long Length, Bright Finish (Uncoated).

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 bright, uncoated finish provides a direct cutting edge for roughing operations where an added coating is not required.
