9/16" OD x 5/8" Shank OD x 1-3/8" LOC x 5" OAL 4-Flute DE HSS Finishing End Mill 30° H NC SQ Regular LHC/LHS TiAlN-HC EDP #86271

9/16" OD x 5/8" Shank OD x 1-3/8" LOC x 5" OAL 4-Flute Double End High-Speed Steel (HSS) Finishing End Mill, 30° Helix, Non-Center Cut, Square End, Regular Length, Left-Hand Cut / Left-Hand Spiral, TiAlN Hard Coat.

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 Left-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 TiAlN Hard Coat is intended for improved heat and wear resistance in demanding finishing applications.
