It features a 1\/4 inch diameter, a 3\/8 inch length of cut, and a 0.02 inch corner radius that reduces stress concentration at the tool tip and extends tool life in demanding applications. The 40-degree helix angle improves chip evacuation and surface finish. A TiCN coating adds hardness and wear resistance, making this tool well suited for ferrous and non-ferrous materials. It is a single-end, centercutting design with right-hand flute direction and right-hand cutting direction. Machinists and tool-and-die professionals are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC machining centers and manual mills for slotting, profiling, and contouring operations where a radiused corner is required on the finished workpiece. The stub length type keeps the tool rigid and minimizes deflection in short-reach applications. The micrograin carbide substrate supports high cutting speeds and feeds. This tool is appropriate for job shops, production machining, and mold and die work where tight tolerances and fine finishes are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.02 inch corner radius reduces edge chipping and stress risers on finished parts\u003c\/li\u003e\n\u003cli\u003eTiCN coating provides increased surface hardness and wear resistance for extended tool life\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip evacuation and improved surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge cuts as well as peripheral and slot milling\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate supports tight diameter tolerance of +0.000000 to -0.002500 inches\u003c\/li\u003e\n\u003cli\u003eStub length construction maximizes rigidity and minimizes deflection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide corner radius end mill for standard 1\/4 inch collet and end mill holder systems on CNC and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or CNC setup technician. The shank should be inserted to the full recommended engagement depth in the collet or end mill holder and torqued per the toolholder manufacturer specification. Inspect the shank and collet bore for chips or damage before seating the tool.
