It features a 3\/8-inch diameter, a 7\/8-inch length of cut, and a 0.0150-inch corner radius that protects the cutting edge and reduces stress concentrations at the bottom of milled slots and pockets. The TiCN coating increases surface hardness and wear resistance, extending tool life in demanding cutting applications. With four flutes and a 40-degree right-hand helix, this end mill is suited for high-feed finishing and semi-finishing passes where surface finish and dimensional accuracy are priorities. Machinists and toolroom professionals are the primary installers and operators of this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in CNC machining centers and manual mills for slotting, profiling, and pocket milling. The centercutting geometry allows plunge entry directly into the workpiece. The single-end, right-hand cutting configuration is standard for conventional and climb milling setups. Its micrograin carbide substrate provides rigidity and edge retention in hardened steels, stainless alloys, and cast iron. It is well suited for mold and die work, aerospace components, and general precision part production where corner breakout is not acceptable.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8-inch diameter with 0.0150-inch corner radius for edge strength and reduced stress risers\u003c\/li\u003e\n  \u003cli\u003eTiCN coating for improved wear resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e4-flute, 40-degree right-hand helix for efficient chip evacuation and smooth surface finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge milling\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eSingle-end construction with 3\/8-inch straight shank for standard collet and end mill holder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for CNC machining centers and manual mills accepting a 3\/8-inch shank end mill holder or collet.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom technician. Secure the shank fully in a clean, properly sized collet or end mill holder and torque to the holder manufacturer's specification. Inspect the shank and collet bore for chips or wear before seating.
