3mm OD x 3/8" Shank OD x 3/8" LOC x 3-1/16" OAL 2-Flute Double End Cobalt High-Speed Steel (HSS) Finishing End Mill, 30° Helix, Center Cut, Square End, Regular Length, Metric Cutting Diameter, TiN-V Coating.
This 2-flute cobalt high-speed steel finishing end mill combines HSS toughness with improved hot hardness for applications that benefit from added heat and wear resistance. 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.
The TiN-V coating provides a hard, low-friction surface for general finishing applications.
