It features a 0.2500 inch mill diameter with six flutes and an AlTiN+ coating, which provides heat resistance and wear protection during aggressive cuts. The 36-40 degree variable helix and variable index geometry reduce chatter and improve chip evacuation. With a 1.2500 inch length of cut and a 3.0000 inch overall length, this end mill suits both finish and roughing passes where tight tolerances and tool life matter. It is used by machinists and CNC operators working in aerospace, defense, and industrial manufacturing environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling high-temperature alloys, including nickel-based superalloys, titanium, and similar difficult-to-cut materials classified under workpiece material code S. The 1\/4 inch shank diameter fits standard collet chucks and shrink-fit holders commonly found on vertical and horizontal machining centers. The right-hand cutting and right-hand flute direction make it compatible with conventional CNC milling setups. Centercutting capability allows plunge entry without a pre-drilled pilot hole, expanding its use in slotting and pocket milling operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in tough alloys\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating provides high-heat and oxidation resistance during dry or near-dry cutting\u003c\/li\u003e\n\u003cli\u003eVariable helix (36-40 degrees) and variable index reduce vibration and improve surface finish\u003c\/li\u003e\n\u003cli\u003eSix-flute design increases feed rate potential and material removal efficiency\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with a 1.2500 inch length of cut and 3.0000 inch overall length\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement end mill for CNC machining centers using 1\/4 inch collet or shrink-fit toolholding systems, with primary application in high-temperature alloy (material code S) milling operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis end mill is installed by machinists or CNC setup technicians using a properly sized collet chuck or shrink-fit holder rated for the 0.2500 inch shank diameter. Ensure the machine spindle is fully stopped and the tool is secured to the specified holder runout tolerance before engaging the workpiece. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when changing cutting tools. Do not exceed the tool's rated length of cut engagement depth during slotting or full-width cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2500 inches (6.35 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: 1.2500 inches (31.75 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.2500 inches (6.35 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\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\u003eHelix Angle\u003c\/strong\u003e: 36-40 degrees\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\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\u003eFlute Type\u003c\/strong\u003e: Helical\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\u003eCoolant Through\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 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: 72011570\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748536353074,"sku":"72011570","price":78.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_7c97a8bc-317a-4bca-9665-2da7b42200d3.jpg?v=1788895000","url":"https:\/\/voomisupply.com\/products\/accupro-72011570-square-end-mill-1-4-in-6-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
