Built from powdered metal and finished with a TiAlN coating, this tool handles demanding cutting tasks while maintaining edge integrity at elevated temperatures. It features a 0.25-inch cutting diameter, 0.625-inch length of cut, and a 2-7\/16-inch overall length. The 3-flute, right-hand cutting geometry with a 30-degree helix delivers efficient chip evacuation and a smooth finish. Centercutting capability allows plunge entry, giving machinists added flexibility in toolpath strategy.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in CNC machining centers and manual mills working with ferrous and non-ferrous metals. The fine pitch, right-hand flute direction, and TiAlN coating make it appropriate for high-speed finishing and chamfering passes on hardened or abrasive materials. The 3\/8-inch shank diameter fits standard collet and end mill holder configurations commonly found in shop and production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiAlN coating improves heat resistance and extends tool life in high-speed cuts\u003c\/li\u003e\n\u003cli\u003ePowdered metal substrate provides consistent hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003e30-degree helix angle promotes smooth chip flow and reduced chatter\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle operation\u003c\/li\u003e\n\u003cli\u003eFine pitch geometry suited for finishing and chamfering passes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use corner chamfer end mill for standard 3\/8-inch collets and end mill holders used in CNC and manual milling applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following standard toolholding procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or holder and torque to the toolholder manufacturer's specification.
