With a 3\/4 inch (0.7500 inch) mill diameter, six flutes, and a 1.0000 inch length of cut, this tool delivers aggressive material removal while maintaining tight tolerances. The AlTiN+ coating provides elevated heat and wear resistance, making the tool well-suited for high-temperature alloy machining where tool life is a critical factor. Variable helix and variable index geometry reduce harmonics and chatter during cutting, improving surface finish and tool stability. It is a single-end, center-cutting tool with right-hand cutting and right-hand helical flutes.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual milling machines where high-temp alloys such as Inconel, titanium, and similar materials are the primary workpiece. The AlTiN+ coating and optimized helix angle of 36 to 40 degrees support extended tool life when running harder materials at elevated spindle speeds. The 3\/4 inch shank diameter matches the mill diameter, allowing direct collet or end mill holder mounting without a reduction sleeve. Machinists and tool-and-die professionals performing aerospace, defense, and energy sector component work will find this geometry particularly appropriate.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and heat resistance in difficult alloy cuts\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating rated for high-temperature alloy (ANSI material code S) applications\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index design reduces chatter and improves surface finish\u003c\/li\u003e\n\u003cli\u003eSix flutes provide high metal removal rates and smooth chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capability allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand helix for standard CNC spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct tooling solution for 3\/4 inch collet chucks, end mill holders, and hydraulic holders used in CNC vertical and horizontal machining centers.

Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before changing tooling. Seat the shank fully into the holder to the recommended gauge line and torque the retention hardware per the holder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut, as excessive runout accelerates wear on carbide tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.7500 inches (19.05 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\u003eShank Diameter\u003c\/strong\u003e: 0.7500 inches (19.05 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 to 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\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\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\u003eCoolant Through\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\u003eSystem of Measurement\u003c\/strong\u003e: Fractional Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.6 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: 72013618\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51755390632242,"sku":"72013618","price":310.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_d07ce18f-ddcf-41b6-b256-553f6beb4519.jpg?v=1788954465","url":"https:\/\/voomisupply.com\/products\/accupro-72013618-3-4-inch-6-flute-solid-carbide-square-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
