1/4" OD x 3/8" Shank OD x 1/4" LOC x 2-5/16" OAL 3-Flute Single End Cobalt High-Speed Steel (HSS) Standard Roughing End Mill, 30° Helix, Non-Center Cut, Square End, Stub Length, Bright Finish (Uncoated).

This 3-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 non-center-cutting geometry is intended for side milling and requires an existing entry path for axial engagement.

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