It measures 5\/16 inches (0.3125 inches) in diameter with a 6-flute configuration and an AlTiN+ coating that provides thermal resistance and extended tool life at elevated cutting temperatures. The corner radius measures 0.060 inches (1.52 mm), reducing stress concentrations at part corners. Variable helix and variable index geometry help reduce harmonic vibration during aggressive cuts. This tool is single-end, center-cutting, and right-hand cutting with right-hand flute direction. It is installed by machinists and tooling professionals working in CNC milling operations.\u003c\/p\u003e\u003cp\u003eThe 72065576 is engineered primarily for cutting high-temperature alloys (material code S), including nickel-based superalloys, titanium alloys, and similar difficult-to-machine materials common in aerospace and power generation work. The 3\/4-inch length of cut and 2-1\/2-inch overall length suit it for standard-depth pocketing, profiling, and finishing passes where corner radius geometry is required. The extended reach option is not enabled on this tool, making it appropriate for shorter-reach setups with maximum rigidity.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN+ coating for high heat resistance and wear reduction in hard and exotic alloys\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index design reduces chatter and improves surface finish\u003c\/li\u003e\n\u003cli\u003e6-flute geometry increases feed rates and productivity in finishing operations\u003c\/li\u003e\n\u003cli\u003e0.060-inch corner radius protects workpiece edges and reduces tool-entry stress\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction for rigidity and dimensional stability\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capability allows plunge entry without pre-drilling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit tooling solution for CNC machining centers accepting a 5\/16-inch shank diameter, specifically suited for high-temperature alloy milling in the ACCUPRO HS series tooling program.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis end mill is installed by qualified machinists in CNC milling equipment. Ensure the spindle and tool holder are fully de-energized and at rest before changing tooling. Use a torque-rated tool holder and collet appropriate for a 5\/16-inch shank to ensure secure clamping and runout control. Follow shop safety protocols and machine manufacturer guidelines when setting tool offsets and depth of cut 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\u003eMill Diameter (mm)\u003c\/strong\u003e: 7.94 mm\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: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (mm)\u003c\/strong\u003e: 19.05 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches (2.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (mm)\u003c\/strong\u003e: 63.50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (mm)\u003c\/strong\u003e: 7.94 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0600 inches (1.52 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN+\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\u003eHelix Style\u003c\/strong\u003e: Variable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eChipbreaker\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: High-Temp Alloy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.09 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: 72065576\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":52087854727474,"sku":"72065576","price":78.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_e9747ef3-b81b-4edb-a496-d2c0ab48519c.jpg?v=1790060573","url":"https:\/\/voomisupply.com\/products\/accupro-72065576-corner-radius-end-mill-5-16-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
