2-1/2" OD x 2-1/2" Shank OD x 4" LOC x 8" OAL 4-Flute SE HSS Finishing End Mill 30° H CC SQ Standard Positive-Lock TiAlN-HC EDP #87311

2-1/2" OD x 2-1/2" Shank OD x 4" LOC x 8" OAL 4-Flute Single End High-Speed Steel (HSS) Finishing End Mill, 30° Helix, Center Cut, Square End, Standard Length, Positive-Lock Style, TiAlN Hard Coat.

This 4-flute high-speed steel (hss) finishing end mill uses a 30° helix and standard length construction for accurate, controlled milling. The square-end geometry is suited to finishing slots, pockets, shoulders, side walls, and flat-bottom features. The center-cutting geometry also supports controlled axial entry, ramping, and pocketing when appropriate for the workpiece and setup. This tool is identified in the source specification as Positive-Lock Style.

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.
