Built from solid carbide with an AlTiN+ coating, it is engineered for cutting high-temperature alloys and similarly hard-to-machine workpiece materials. The 3\/4 inch (0.7500 inch) diameter body features 6 helical flutes with a variable helix angle between 36 and 40 degrees and a variable index geometry. These design elements reduce harmonic vibration and improve chip evacuation during aggressive cuts. Licensed machinists and CNC operators running production or job-shop work on aerospace-grade or heat-resistant alloys are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling operations on high-temperature alloys, including nickel-based, cobalt-based, and titanium alloys, where tool life and edge stability are critical. The AlTiN+ coating provides thermal resistance and hardness at the cutting edge, extending tool life in high-heat cutting environments. With a 1.6250 inch length of cut and a 4.0000 inch overall length, it fits standard 3\/4 inch toolholders on vertical and horizontal machining centers. The centercutting capability allows for plunge entry. It is sold as a single end, single piece unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eAlTiN+ coating rated for high-temperature alloy cutting (primary workpiece material code: S)\u003c\/li\u003e\n\u003cli\u003e6-flute helical design with variable helix (36-40 degrees) and variable index to reduce chatter\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle operation\u003c\/li\u003e\n\u003cli\u003eSingle-end tool with no coolant-through feature; suited for flood or mist coolant delivery\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 3\/4 inch diameter end mill toolholders on CNC vertical or horizontal machining centers.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the toolholder. Use a properly sized collet or shrink-fit holder rated for 3\/4 inch shank diameter and torque the retention mechanism per the toolholder manufacturer specification. Confirm correct spindle direction (right-hand) before initiating a cut, and verify that cutting parameters match the workpiece material and coating requirements.\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\u003eShank 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: 1.6250 inches (41.28 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0000 inches (101.60 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\u003eCentercutting\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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\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: 0.77 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: 72098304\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51737309118770,"sku":"72098304","price":306.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_557f2469-574a-4373-ac5b-ebce11c034fd.jpg?v=1788786915","url":"https:\/\/voomisupply.com\/products\/accupro-72098304-3-4-inch-6-flute-solid-carbide-square-end-mill","provider":"Voomi Supply","version":"1.0","type":"link"}
