At 5\/16 inch (0.3125 inches) in diameter, it features 6 flutes with a variable helix and variable index geometry that reduces chatter and improves chip evacuation. The AlTiN+ coating provides heat resistance and extended tool life when cutting high-temperature alloys and other hard materials. With a 1-inch length of cut and a 3-inch overall length, this end mill suits finishing and semi-finishing passes where tight tolerances and edge integrity are critical. It is centercutting and right-hand fluted, making it suitable for plunge entry and conventional or climb milling operations.\u003c\/p\u003e\u003cp\u003eThis end mill is built primarily for high-temp alloys (ANSI material code S), including nickel-based superalloys, titanium, and cobalt-chrome alloys commonly found in aerospace, medical, and power generation component work. It fits standard 5\/16-inch collets and tool holders used on vertical machining centers and CNC mills. The 0.030-inch corner radius protects the cutting edge, reduces stress concentration at the corner, and leaves a controlled radius in milled pockets and slots rather than a sharp 90-degree break.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard, abrasive materials\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating for elevated heat tolerance and extended tool life in high-temp alloys\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index geometry reduce harmonic vibration and chatter\u003c\/li\u003e\n\u003cli\u003e0.030-inch (0.76 mm) corner radius protects edge integrity and reduces stress in the workpiece\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge milling entry\u003c\/li\u003e\n\u003cli\u003e6-flute configuration supports higher feed rates and improved surface finish\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 5\/16-inch collet-style or shrink-fit tool holders on CNC vertical machining centers and milling machines.

Use a calibrated torque wrench and the tool holder manufacturer's specified clamping procedure when securing the end mill in a collet or shrink-fit holder. Confirm runout with a dial indicator before production cuts. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and coating type.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inch (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: 1 inch (25.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches (76.20 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.030 inches (0.76 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 (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: 0.11 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 72019359\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730086625586,"sku":"72019359","price":84.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_976dc4b0-cb76-4f3f-968a-150c89f3d832.jpg?v=1788711531","url":"https:\/\/voomisupply.com\/products\/accupro-72019359-corner-radius-end-mill-5-16-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
