Built to a 0.5000 inch diameter with six flutes, it delivers a 1 inch length of cut and carries an AlTiN+ coating engineered for heat and oxidation resistance in high-temp alloy applications. The variable helix and variable index geometry reduce harmonic vibration and chatter, improving surface finish and tool life in difficult cuts. At 3 inches overall length, it fits standard toolholders used in CNC machining centers. This tool is installed and operated by machinists and CNC programmers working in aerospace, energy, and industrial manufacturing environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is optimized for cutting high-temperature alloys, including nickel-based superalloys and similar difficult-to-machine materials classified under material code S. The 0.0300 inch corner radius protects the cutting edge from chipping at the corner while maintaining tight dimensional control. The centercutting design allows plunge entry. Right-hand flute direction and right-hand cutting direction are standard for conventional CNC spindle setups. The HS series designation places this tool in a high-performance family intended for aggressive material removal rates in production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlTiN+ coating provides elevated heat resistance for dry and high-speed cutting in high-temp alloys\u003c\/li\u003e\n  \u003cli\u003eVariable helix and variable index geometry reduce chatter and improve surface finish\u003c\/li\u003e\n  \u003cli\u003e0.0300 inch corner radius protects cutting edge and extends tool life at the corner\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003eCentercutting design supports plunge milling and ramping entry\u003c\/li\u003e\n  \u003cli\u003eSix-flute configuration increases feed rate capability and productivity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide end mill for use in CNC machining centers with standard 1\/2 inch diameter toolholding systems.

Ensure the spindle is fully stopped and the machine is in a safe state before tool changes. Secure the shank in a compatible 1\/2 inch collet, end mill holder, or shrink-fit holder torqued to the toolholder manufacturer's specification. Verify runout with a dial indicator before production cuts, as excessive runout accelerates wear and degrades surface finish on high-temp alloys.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 inches (12.70 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: 0.5000 inches (12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute 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\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: 0.26 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: 72020860\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727900180786,"sku":"72020860","price":128.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_17a8c17e-43a3-4fbb-b7a1-7e5cabd05d0e.jpg?v=1788684235","url":"https:\/\/voomisupply.com\/products\/accupro-72020860-corner-radius-end-mill-1-2-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
