It features a 5\/16 inch mill diameter, a 3\/4 inch length of cut, and a 0.02 inch corner radius that reduces stress concentrations at the cutting edge and extends tool life in demanding applications. The micrograin carbide substrate and AlTiN+ coating provide high hardness and heat resistance, making this end mill well suited for cutting hardened steels, stainless, and high-temperature alloys. It is a single-end, centercutting tool with a right-hand flute direction and right-hand cutting direction. Installation and setup are handled by CNC machinists and tool crib technicians.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC vertical and horizontal machining centers where corner radius profiling, slotting, and peripheral milling are required. The 4-flute, spiral flute geometry and 40-degree helix angle support efficient chip evacuation and smooth surface finish in both roughing and finishing passes. The straight cylindrical shank with a 5\/16 inch diameter fits standard collet chucks and end mill holders. It is suited for job shops, tool-and-die operations, and production machining environments working with ferrous and difficult-to-machine materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.02 inch corner radius reduces edge chipping and improves part surface finish at corners\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating delivers high oxidation resistance and extends cutting life in hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate provides rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003e4-flute spiral geometry with 40-degree helix angle promotes efficient chip flow and smooth finish\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge milling in addition to peripheral and slot cutting\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with straight cylindrical shank for direct collet or end mill holder mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-stock cutting tool for CNC machining centers accepting 5\/16 inch straight cylindrical shank end mill holders or ER collet chucks.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed by CNC machinists or toolroom personnel using appropriate collet chucks or end mill holders rated for the shank diameter. The machine spindle must be fully stopped and the tool holder must be de-energized before changing tooling. Verify runout with a dial indicator after mounting to confirm concentricity within acceptable tolerance. Consult the machine tool manufacturer and cutting tool data for recommended speeds and feeds before use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inches (0.1875 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0200 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus or minus 0.001 inches\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\u003c\/strong\u003e: 5\/16 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\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN+\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6\/44\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\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: 14556400\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727387754802,"sku":"14556400","price":99.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05a5a9f28df55cfda8731da1de0b3eca.jpg?v=1788677167","url":"https:\/\/voomisupply.com\/products\/accupro-14556400-corner-radius-end-mill-5-16-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
