The 0.75-inch diameter tool features a 6-flute geometry with a 0.09-inch (2.28 mm) corner radius, variable helix, and variable index design that reduces chatter and improves surface finish at aggressive feed rates. An AlTiN+ coating provides thermal resistance and oxidation protection, extending tool life when cutting nickel, titanium, and other superalloys at elevated cutting temperatures. This end mill is single-end, right-hand cut, and center-cutting, making it suitable for plunge entry as well as peripheral and slot milling operations. Licensed machinists and CNC operators in aerospace, defense, and energy sectors are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers and milling machines where high-temperature alloys such as Inconel, Hastelloy, titanium, and similar S-category materials are the primary workpiece. The 3.25-inch length of cut and 6-inch overall length support deep-pocket and long-reach applications where a standard-length tool would fall short. The 0.75-inch shank diameter mates directly with standard ER or hydraulic toolholders in that bore size. Applications span aerospace structural components, turbine hardware, and oil-and-gas downhole parts where tight tolerances and hard materials are the norm.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and heat resistance in S-category superalloy cutting\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating delivers thermal barrier protection and reduced friction at high cutting speeds\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index flute geometry minimize harmonic vibration and chatter\u003c\/li\u003e\n\u003cli\u003e6-flute design supports high feed rates and improved finish in finishing and semi-finishing passes\u003c\/li\u003e\n\u003cli\u003e0.09-inch corner radius reduces stress concentration at the cutting edge and extends tool life\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capability allows direct plunge entry without a pilot hole\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with high-temperature alloys (UNSPSC material code S) including nickel-based and titanium-based superalloys.

Seat the 0.75-inch shank fully into a clean, properly sized collet or hydraulic chuck and torque the retention nut to the toolholder manufacturer's specification. Verify runout with a dial indicator before committing to a production cut, as excessive runout will accelerate edge wear and reduce surface finish quality on superalloy workpieces. Follow the cutting tool manufacturer's recommended speeds and feeds for AlTiN-coated carbide in high-temperature alloy — do not extrapolate from steel or aluminum parameters.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.75 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: 3.25 inches (82.55 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches (152.4 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.75 inches (19.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.09 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\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\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\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\u003eSeries\u003c\/strong\u003e: HS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.21 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: 72027360\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51753163489586,"sku":"72027360","price":422.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_3da3a617-c26d-4ae8-965a-ff69e96060e1.jpg?v=1788933404","url":"https:\/\/voomisupply.com\/products\/accupro-72027360-corner-radius-end-mill-3-4-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
