It features a 3\/8-inch (0.3750-inch) mill diameter, six flutes, and a variable helix and variable index geometry that reduces harmonic chatter and improves surface finish at higher feed rates. The AlTiN+ coating provides thermal resistance and extended tool life when cutting difficult materials. With a 1-inch length of cut and a 3-inch overall length, this end mill suits tight-tolerance profiling, slotting, and finishing passes in CNC machining centers operated by machinists working in aerospace, energy, and precision manufacturing environments.\u003c\/p\u003e\u003cp\u003eThis end mill is engineered specifically for cutting high-temperature alloys, designated by primary workpiece material code S. Typical applications include profiling and finishing passes on nickel-based superalloys, titanium alloys, and other hard-to-machine aerospace and energy materials. The 0.0900-inch corner radius reduces stress concentration at the cutting edge, extending tool life during aggressive cuts. It is suited for use in rigid CNC setups where consistent chip evacuation and thermal management are critical to part quality and tool longevity.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVariable helix and variable index geometry reduces chatter and improves surface finish\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating delivers high thermal resistance for cutting high-temp alloys\u003c\/li\u003e\n\u003cli\u003e0.0900-inch corner radius reduces cutting-edge stress and extends tool life\u003c\/li\u003e\n\u003cli\u003eSix-flute configuration supports higher feed rates and finer finishes\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows plunge entry and ramping operations\u003c\/li\u003e\n\u003cli\u003eRight-hand flute direction and right-hand cutting orientation for standard CNC spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard fitment end mill for CNC machining centers requiring a 3\/8-inch shank, single-end solid carbide corner radius tool rated for high-temperature alloy cutting.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before inserting or removing the tool from the tool holder. Use a properly sized collet or end mill holder matched to the 3\/8-inch shank diameter to prevent runout. Verify tool projection and reach before beginning any cutting program.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3750 inches (9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3750 inches (9.53 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: 1.0000 inches (25.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0000 inches (76.20 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0900 inches (2.28 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\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\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\u003eWeight\u003c\/strong\u003e: 0.14 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: 72077985\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730552783154,"sku":"72077985","price":81.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_0bab05e5-5052-4ad5-8636-dbe1d9920a69.jpg?v=1788719476","url":"https:\/\/voomisupply.com\/products\/accupro-72077985-corner-radius-end-mill-3-8-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
