1/4" OD x 3/8" Shank OD x 5/8" LOC x 2-1/2" OAL 3-Flute Single End HSS Roughing End Mill 30° Helix Non-Center Cut Regular Length Square End TiCN Premium Grade Coating.
This 3-flute high-speed steel roughing end mill uses chip-breaking cutting edges to reduce cutting pressure and support efficient stock removal. The regular length construction and 30° helix are suited to roughing slots, pockets, shoulders, and profiles while promoting manageable chips. Its non-center-cutting geometry is intended for side milling and requires an existing entry path for axial engagement.
High-speed steel provides toughness and resistance to chipping for general machining, repair work, interrupted cuts, and setups that benefit from a more forgiving cutting edge than carbide.
The TiCN Premium Grade coating provides a hard, low-friction surface intended to improve wear resistance in suitable milling applications.
