It features a 5\/16-inch diameter, a 7\/16-inch length of cut, and a 2-inch overall length. The 4-flute, right-hand spiral configuration with a 38-degree helix angle promotes efficient chip evacuation and smooth cutting action. An AlCrTiN coating provides thermal resistance and extended tool life in demanding cutting environments. The micrograin carbide substrate delivers edge integrity at high cutting speeds. Center cutting geometry allows plunge entry, making this tool suitable for slot milling, profiling, and ramping operations.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC machining centers and manual mills for finishing and semi-finishing ferrous and hard alloy workpieces. The corner radius end type reduces stress concentration at the cutting edge and produces a controlled radius at the base of milled features. The straight-cylindrical shank seats securely in standard collet chucks and end mill holders. It is a single-end tool intended for production environments where consistent tolerances and repeatability are required. Machinists and CNC programmers working in job shops, tool rooms, and production machining facilities are the primary users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlCrTiN coating for high-temperature wear resistance in ferrous and hard-material cuts\u003c\/li\u003e\n\u003cli\u003e4-flute, right-hand spiral design with 38-degree helix for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eCenter cutting capability allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for edge stability and dimensional consistency\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces harmonic vibration during cuts\u003c\/li\u003e\n\u003cli\u003eCorner radius geometry minimizes edge chipping and extends tool life at feature corners\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard production tool for use in standard 5\/16-inch collet chucks, shrink-fit holders, and end mill holders on CNC machining centers and manual knee mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the machine spindle fully stopped and the control in an e-stop or lockout state. Seat the straight-cylindrical shank fully into the holder and tighten to the holder manufacturer's specified clamping procedure. Inspect the corner radius and cutting edges under magnification before use to confirm the tool arrived undamaged. Follow your facility's speeds-and-feeds library for solid carbide end mills with AlCrTiN coating when establishing initial cutting parameters.\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: 7\/16 inches (0.4375 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: 5\/16 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\u003eCorner Radius Tolerance\u003c\/strong\u003e: +0.00200 to -0.00200 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.001000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 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: AlCrTiN\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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: 310162\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731123044658,"sku":"310162","price":77.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/416be3be78d6663d5ce09f19074ce3c6_39a0bca9-8702-4eff-aafa-172fd808fee4.jpg?v=1788727209","url":"https:\/\/voomisupply.com\/products\/accupro-310162-corner-radius-end-mill-5-16-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
