With a 1\/4 inch diameter, a 0.01 inch corner radius, and an AlTiN coating, this tool is built for high-heat applications involving hardened steels, stainless steels, and other difficult-to-machine alloys. The three-flute, right-hand spiral geometry promotes efficient chip evacuation while maintaining a strong core. Centercutting capability allows plunge entry without a pre-drilled hole. Machinists and tool-and-die professionals reach for this end mill when tight tolerances and extended tool life are both priorities.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for contouring, slotting, and profiling operations on CNC machining centers and manual mills. The 3\/8 inch length of cut handles shallow-to-moderate depth passes, while the 2 inch overall length keeps the tool rigid and minimizes deflection. The 1\/4 inch shank fits standard collet chucks and end mill holders common in job shops, production facilities, and toolrooms. It is a single-end tool intended for right-hand cutting with right-hand flute direction.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiN coating provides high-temperature oxidation resistance for dry or minimal-lubricant cutting\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate delivers hardness and wear resistance across a broad range of materials\u003c\/li\u003e\n  \u003cli\u003e0.01 inch corner radius reduces stress concentration at the cutting edge and extends tool life vs. a sharp-corner end mill\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits direct plunge entry\u003c\/li\u003e\n  \u003cli\u003eThree-flute, right-hand spiral geometry balances chip clearance and cutting-edge strength\u003c\/li\u003e\n  \u003cli\u003eCorner radius tolerance of plus or minus 0.0015 inches and mill diameter tolerance of plus 0.0002 to minus 0.0008 inches support tight-tolerance work\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct substitute for 1\/4 inch shank corner radius end mills used in CNC and manual milling applications requiring a 0.01 inch radius, 3\/8 inch length of cut, and AlTiN coating on solid carbide tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists following standard tool-holding practices. Always power down and lock out the spindle before changing tooling. Seat the 1\/4 inch shank fully into the collet or end mill holder and torque the retention device per the tool holder manufacturer specification. Inspect the cutting edges and coating for chips or wear before each use, and confirm runout at the holder before committing to a finishing pass.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.01 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus or minus 0.0015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus 0.0002 to minus 0.0008 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: minus 0.0001 to minus 0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.12 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 12179350\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51743118786866,"sku":"12179350","price":45.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/12e70355284210ff265bfdb03700cfec.jpg?v=1788842891","url":"https:\/\/voomisupply.com\/products\/accupro-12179350-corner-radius-end-mill-1-4-in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
