5/16" OD x 3/8" Shank OD x 9/16" LOC x 2-5/16" OAL 2-Flute Single End HSS Keyway Cutter 30° Helix Center Cut Regular Length Keyway Tolerance Square End TiN-V Coating.
This 2-flute high-speed steel keyway cutter is manufactured to keyway-tolerance geometry for producing accurate keyways, slots, and grooves. The regular-length construction balances reach and rigidity, while the 30° helix supports 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 TiN-V coating provides a hard, low-friction surface for general keyway and slotting applications.
