Built to a 0.375 inch diameter with a 0.0300 inch corner radius, this 6-flute, single-end tool delivers fine surface finishes and extended tool life in demanding cutting environments. The stub-length geometry with a 0.5000 inch length of cut provides rigidity and reduced deflection in tight-clearance setups. An AlTiN coating adds thermal resistance, making this tool well-suited for high-speed and dry machining applications. Machinists and tool-and-die professionals working in job shops, production environments, or toolroom settings will find this end mill appropriate for finishing passes and corner-breaking work.\u003c\/p\u003e\u003cp\u003eThis end mill is used in vertical and horizontal machining centers, CNC mills, and manual knee mills where a corner radius profile is required to reduce stress concentrations at workpiece corners or to produce radiused slots and pockets. The centercutting design allows plunge entry, giving programmers flexibility in toolpath strategy. The right-hand flute direction and right-hand cutting orientation are standard for conventional CNC milling setups. Typical applications include mold and die work, aerospace component finishing, and precision fixture machining where tight tolerances and controlled corner geometry are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.0300 inch corner radius reduces stress concentrations and produces clean radiused corners in one pass\u003c\/li\u003e\n\u003cli\u003e6-flute configuration increases feed rate potential and improves surface finish compared to 4-flute geometry\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides high-temperature oxidation resistance for dry or minimal-lubrication cutting\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate offers hardness and wear resistance in hardened steels and cast iron\u003c\/li\u003e\n\u003cli\u003eCentercutting design permits plunge milling and ramp entry without a pilot hole\u003c\/li\u003e\n\u003cli\u003eStub length of cut (0.5000 inches) maximizes rigidity and minimizes tool deflection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling option for standard 3\/8 inch collet or end mill holder systems used in CNC machining centers and manual mills accepting right-hand solid carbide end mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires a clean, properly sized collet or end mill holder matched to the 3\/8 inch shank diameter. Ensure the spindle and holding system are fully de-energized and the machine is in a safe lockout state before tool changes. Verify runout with a dial indicator before cutting — the maximum TIR for this tool is 0.0005 inches. Follow the machining center manufacturer guidelines and applicable shop safety codes when setting tool offsets and spindle speeds.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 25 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.002000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum TIR\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2500118\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731457474866,"sku":"2500118","price":143.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b7a342d10e18933a07724a736c8efeef.jpg?v=1788731342","url":"https:\/\/voomisupply.com\/products\/accupro-2500118-corner-radius-end-mill-3-8-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
