With a 1\/4 inch mill diameter and a 0.02 inch corner radius, this single-end tool produces smooth corner transitions and reduces stress concentrations in milled pockets and profiles. The 4-flute configuration supports efficient chip evacuation while maintaining surface finish quality. A 40-degree helix angle promotes smooth cutting action and reduces chatter. This tool is installed and operated by machinists and tool-and-die professionals on CNC and manual milling equipment.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits stub-length applications where rigidity is a priority over reach. The 3\/8 inch length of cut and 2 inch overall length make it well-suited for shallow pocket milling, contour profiling, and finish passes in ferrous and non-ferrous materials. The bright\/uncoated finish is appropriate for general-purpose use and compatible with a range of cutting fluids and dry cutting setups. The 1\/4 inch shank diameter fits standard ER and end mill holders commonly found in production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for wear resistance and dimensional stability\u003c\/li\u003e\n  \u003cli\u003e0.02 inch corner radius reduces corner chipping and stress risers in workpiece geometry\u003c\/li\u003e\n  \u003cli\u003e4-flute, right-hand spiral design supports both slotting and peripheral milling\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes smooth cutting and reduced vibration\u003c\/li\u003e\n  \u003cli\u003eCentercutting capable, allowing plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eBright\/uncoated finish suitable for general-purpose milling across a wide range of materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide corner radius end mill for standard 1\/4 inch shank end mill holders and collet chucks used in CNC machining centers and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists using appropriate end mill holders or collet chucks rated for the 1\/4 inch shank diameter. Ensure the machine spindle is fully stopped and locked out before tool changes. Confirm runout and tool projection before beginning a cut.
