With a 0.75-inch (19.05 mm) mill diameter, 6 flutes, and a 3.25-inch length of cut, this tool delivers aggressive material removal while maintaining surface finish quality. The AlTiN+ coating provides enhanced heat resistance and tool life when working in high-temperature alloys and other difficult-to-machine materials. Variable helix and variable index geometry reduce harmonic vibration and chatter during long-reach cuts. Installed by machinists and tool-and-die professionals on CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for milling high-temperature alloys (material code S), including nickel-based superalloys, titanium, and similar aerospace-grade materials where heat generation and tool wear are primary concerns. The single-end configuration, straight shank, and 0.75-inch shank diameter allow direct toolholder mounting in standard collet chucks, end mill holders, and shrink-fit systems. The 36-40 degree variable helix angle improves chip evacuation in deep-pocket and slot-milling operations. It is not centercutting-limited and supports plunge and ramping entries.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in abrasive materials\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating for oxidation resistance and extended tool life in high-temp alloys\u003c\/li\u003e\n\u003cli\u003eVariable helix (36 and 40 degrees) and variable index reduce chatter and vibration\u003c\/li\u003e\n\u003cli\u003e6-flute, right-hand helical geometry maximizes feed rates and surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge, ramp, and helical entry paths\u003c\/li\u003e\n\u003cli\u003e3.25-inch length of cut supports deep-pocket and long-reach milling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 3\/4-inch collet chucks, end mill holders, and shrink-fit toolholders.

Ensure the toolholder bore and shank are clean and free of chips or coolant residue before seating. Confirm proper stick-out length to balance rigidity against reach requirements before beginning a cut. Power down and lock out the spindle before changing or inspecting tooling.\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\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\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: 6.0 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\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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 Angle\u003c\/strong\u003e: 36 and 40 degrees (Variable)\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\u003eChipbreaker\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: High-Temp Alloy (S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HS\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: 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: 72039068\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51746978529586,"sku":"72039068","price":462.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_11dcf9bd-2b15-4954-a45e-684cd09d5566.jpg?v=1788875077","url":"https:\/\/voomisupply.com\/products\/accupro-72039068-ball-end-mill-3-4-in-6-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
