It carries a 0.3125-inch (5\/16 inch) mill diameter, a 6-flute geometry, and an AlTiN+ coating that supports elevated cutting temperatures without breakdown. The variable helix and variable index design reduce harmonic chatter, improving surface finish and tool life in difficult cuts. With a 0.0100-inch corner radius, it protects the cutting edge at the transition zone while maintaining tight corner tolerances. This tool is suited for machinists and tool-and-die professionals working in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is optimized for cutting high-temperature alloys, classified under primary workpiece material code S. Typical applications include aerospace components, medical device machining, and industrial parts where nickel-based superalloys, titanium, and cobalt-chrome alloys are common. The center-cutting capability allows plunge entry, making it useful for ramping and helical interpolation operations. The right-hand flute direction and right-hand cutting orientation are standard for conventional CNC machining centers. Overall length is 2.0 inches, with a 7\/16-inch length of cut and a 5\/16-inch shank diameter matching the mill diameter for direct collet or end mill holder mounting.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiN+ coating provides oxidation resistance and hardness retention at high cutting temperatures\u003c\/li\u003e\n  \u003cli\u003eVariable helix and variable index geometry reduce chatter and improve surface finish\u003c\/li\u003e\n  \u003cli\u003e6-flute design increases feed rate potential and core strength compared to 4-flute tools\u003c\/li\u003e\n  \u003cli\u003e0.0100-inch corner radius protects the cutting edge and reduces stress concentration at corners\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting construction allows plunge, ramp, and helical entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction delivers rigidity and wear resistance in abrasive and hard workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in high-temperature alloy machining applications (material code S), including nickel, titanium, and cobalt-based superalloys.

Ensure the machine spindle and toolholder are clean and free of chips before seating the shank to full engagement depth. Do not exceed the recommended overhang length for the application, as carbide is rigid but brittle under side-loading beyond design parameters. Verify runout at the tool tip with a dial indicator before beginning production cuts, particularly when working in expensive or difficult-to-replace workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3125 inches (5\/16 inch)\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: 0.4375 inches (7\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.0 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3125 inches (5\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0100 inches (0.25 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\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\u003eVariable Helix\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\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 (Code S)\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: 0.07 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: 72058712\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739013447986,"sku":"72058712","price":66.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_adc5aa0c-eae7-4449-8ae8-2533806e8ac4.jpg?v=1788807975","url":"https:\/\/voomisupply.com\/products\/accupro-72058712-corner-radius-end-mill-6-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
