3/16" OD x 3/8" Shank OD x 5/8" LOC x 2-1/2" OAL 2-Flute Single End High-Speed Steel (HSS) Finishing End Mill, 37° Helix, Center Cut, Square End, Regular Length, Aluminum-Cutting Geometry, TiCN Premium Grade Coating.
This 2-flute high-speed steel (hss) finishing end mill uses a 37° 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 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 Aluminum-Cutting Geometry.
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 TiCN Premium Grade coating provides a hard, low-friction surface intended to improve wear resistance in suitable milling applications.
