It features a 5\/16 inch diameter, a 3\/4 inch length of cut, and a 0.06 inch corner radius that reduces stress concentrations at the tool tip and extends tool life in demanding applications. The 4-flute, right-hand spiral geometry provides efficient chip evacuation and a smooth finish in finishing and semi-finishing passes. An AlTiN+ coating boosts heat resistance and surface hardness, making this end mill well-suited for high-speed dry or near-dry cutting. Machining professionals and tool and die shops specify this type of tool for tight-tolerance work where edge chipping and corner breakdown are primary concerns.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in vertical machining centers, CNC mills, and manual knee mills running materials such as alloy steels, stainless steels, hardened steels, and cast iron. The single-end, centercutting design allows plunge entry as well as peripheral and slot milling. With a 2-1\/2 inch overall length and a 5\/16 inch straight-cylindrical shank, it fits standard ER collets and end mill holders commonly found in production and job shop environments. The Series 6\/44 designation and micrograin carbide substrate make it a reliable choice for shops running tight-tolerance die work or contoured part profiles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.06 inch corner radius reduces stress risers and edge chipping on profiled cuts\u003c\/li\u003e\n  \u003cli\u003eAlTiN+ coating provides elevated heat resistance for high-speed and dry cutting\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate delivers rigidity and dimensional stability\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry permits direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand spiral flutes with 40-degree helix angle optimize chip flow and surface finish\u003c\/li\u003e\n  \u003cli\u003eStraight-cylindrical shank fits standard ER collets and shrink-fit holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard production end mill for CNC and manual milling machines accepting a 5\/16 inch straight-cylindrical shank with ER or end mill holder tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and locked out before seating or removing any cutting tool. Verify collet bore size matches the 5\/16 inch shank diameter and torque the collet nut to the holder manufacturer's specification. Inspect the shank and collet bore for chips or runout before tightening, as even minor contamination will affect tool life and dimensional accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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 (0.5000 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0600 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 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 Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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\u003eCoating\u003c\/strong\u003e: AlTiN+\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus or minus 0.00100 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 Tolerance\u003c\/strong\u003e: +0.0001 \/ -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6\/44\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.5 inches L x 0.31 inches W x 0.31 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 14556402\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51755885953330,"sku":"14556402","price":100.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d843139684298f58e73bc3f31ed1f1da.jpg?v=1788961124","url":"https:\/\/voomisupply.com\/products\/accupro-14556402-corner-radius-end-mill-5-16-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
