5/16" OD x 3/8" Shank OD x 3/4" LOC x 2-1/2" OAL 4-Flute Single End High-Speed Steel (HSS) Finishing End Mill, 30° Helix, Non-Center Cut, Square End, Regular Length, Right-Hand Cut / Left-Hand Spiral, Bright Finish (Uncoated).
This 4-flute high-speed steel (hss) finishing end mill uses a 30° helix and regular length construction for accurate, controlled milling. The square-end geometry is suited to finishing slots, pockets, shoulders, side walls, and flat-bottom features. The non-center-cutting geometry is intended for side milling and requires an existing entry path for axial engagement. This tool is identified in the source specification as Right-Hand Cut / Left-Hand Spiral.
High-speed steel provides toughness and resistance to chipping for general machining, repair work, interrupted cuts, and setups that benefit from a forgiving cutting edge.
The bright, uncoated finish provides a direct cutting edge for general finishing where an added coating is not required.
