The tool measures 0.3125 inches in diameter with a 6-flute configuration and carries an AlTiN+ coating for extended tool life under high-heat cutting conditions. A corner radius of 0.030 inches reduces stress concentration at the cutting edge and improves surface finish on finished workpiece corners. Variable helix and variable index geometry help suppress chatter and improve chip evacuation. This end mill is installed and run by machinists and CNC programmers working in precision metal removal environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is engineered for cutting high-temperature alloys, including nickel-based superalloys and titanium alloys, where heat resistance and edge retention are critical. The AlTiN+ coating performs well in dry or minimal-lubrication cutting strategies common in aerospace and high-temp alloy machining. With right-hand flute direction and right-hand cutting direction, it suits standard CNC machining center spindle configurations. The 2-inch overall length and 0.3125-inch shank diameter make it compatible with standard collet and end mill holder tooling at that bore size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in high-temp alloy cutting\u003c\/li\u003e\n  \u003cli\u003eAlTiN+ coating provides oxidation resistance and hardness at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003e6-flute design increases feed rate capability and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eVariable helix and variable index geometry reduce harmonic vibration and chatter\u003c\/li\u003e\n  \u003cli\u003e0.030-inch corner radius protects the cutting edge and improves corner geometry on the workpiece\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capability allows plunge entry into the workpiece\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers with standard collet or end mill holder tooling accepting a 0.3125-inch shank diameter.

Secure the shank in a properly sized collet or end mill holder to the holder manufacturer's recommended torque specification. Verify runout with a dial indicator before cutting to protect both the tool and workpiece. Follow the cutting tool manufacturer's recommended speeds and feeds for the specific workpiece material and coating.\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 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: 0.030 inches\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\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\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: 0.07 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: 72058357\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51754809655602,"sku":"72058357","price":74.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_2e76a6ae-2cf8-4b28-8516-f68c9c60be74.jpg?v=1788948783","url":"https:\/\/voomisupply.com\/products\/accupro-72058357-corner-radius-end-mill-5-16-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
