It features a 1\/4 inch cutting diameter, a 1-1\/8 inch length of cut, and a 3 inch overall length with a 1\/4 inch shank. The TiCN (titanium carbonitride) coating improves surface hardness and reduces friction at the cutting edge, extending tool life in abrasive materials. The micrograin carbide substrate provides rigidity and wear resistance suited to high-speed finishing and light roughing passes.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in vertical milling machines, CNC machining centers, and manual knee mills where a 1\/4 inch collet or end mill holder is available. The long-length classification makes it well suited for reaching into pockets or slots where standard-reach tooling cannot access. It is appropriate for cutting aluminum, steel, stainless, and similar materials in job shop, production, and tool-and-die environments. Installation and use should be performed by qualified machinists following shop safety protocols.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiCN coating for improved hardness and reduced cutting friction\u003c\/li\u003e\n\u003cli\u003e4-flute, spiral configuration with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute for standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eLong-length classification for extended reach into deep pockets and slots\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide square end mill for use in any 1\/4 inch collet, end mill holder, or compatible tool holder accepting a 1\/4 inch straight shank.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist with the machine powered down and the spindle locked before seating or removing the tool. Ensure the shank is fully seated in the holder and that runout is checked before initiating cuts.
