5/16" OD x 5/16" Shank OD x 15/32" LOC x 1-9/16" OAL 2-Flute Single End HSS Screw Machine End Mill 30° Helix Center Cut Stub Length Square End TiCN Premium Grade Coating.
This 2-flute high-speed steel screw-machine-length end mill is designed for rigid, short-reach milling with reduced deflection. The stub-length construction supports accurate slotting, pocketing, and profile milling, while the 30° helix promotes smooth chip evacuation. Its center-cutting geometry supports controlled axial entry, ramping, and pocketing when appropriate for the workpiece and setup.
High-speed steel provides toughness and resistance to chipping for general machining, repair work, and applications that benefit from a more forgiving cutting edge than carbide.
The TiCN Premium Grade coating provides a hard, low-friction surface intended to improve wear resistance in suitable milling applications.
