7/16" OD x 1/2" Shank OD x 1-3/4" LOC x 3-3/4" OAL 4-Flute Single End Cobalt High-Speed Steel (HSS) Truncated-Tooth Roughing End Mill, 30° Helix, Non-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 truncated-tooth roughing profile breaks chips and distributes cutting load for productive stock removal before semi-finishing or finishing operations. 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.
