It features a 1\/2 inch (6.35 mm) mill diameter with six flutes and an AlTiN+ coating that provides thermal resistance and extended tool life under aggressive cutting conditions. The variable helix angle, ranging from 36 to 40 degrees, combined with a variable index design, suppresses chatter and improves surface finish. This end mill is center-cutting, allowing direct plunge entry. It is suited for use by machinists and CNC operators working in aerospace, defense, and other precision manufacturing environments.\u003c\/p\u003e\u003cp\u003eThis end mill is designed for milling high-temp alloys (material code S), including nickel-based superalloys, titanium, and similar materials that generate significant cutting heat. The 1\/2 inch shank diameter matches the mill diameter, making it compatible with standard ER and side-lock toolholders of that bore size. With a 1.0 inch length of cut and a 3.0 inch overall length, it fits standard toolholder setups without extended reach. It is not configured for coolant-through delivery, so flood or mist coolant applied externally is the typical approach for heat management in these materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN+ coating provides high thermal resistance for extended tool life in heat-generating alloys\u003c\/li\u003e\n\u003cli\u003eVariable helix (36-40 degrees) and variable index reduce vibration and chatter during aggressive cuts\u003c\/li\u003e\n\u003cli\u003eSix-flute helical design increases feed rates and improves finish compared to lower-flute-count tools\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows direct plunge milling without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction maintains rigidity and edge integrity in hard and abrasive workpiece materials\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with right-hand cut and right-hand flute direction for standard spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard 1\/2 inch bore toolholders on CNC machining centers.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the toolholder. Use a calibrated torque wrench when tightening collet nuts or set screws to the toolholder manufacturer specification. Verify runout with a dial indicator after installation before beginning any cutting operation, as excessive runout accelerates edge wear and reduces surface finish quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 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: 1.0000 inches (25.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches (12.70 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\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\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: 0.26 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: 72009962\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51751346929970,"sku":"72009962","price":114.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_7cccb565-d043-48b3-a6b0-375dee4f73ee.jpg?v=1788922980","url":"https:\/\/voomisupply.com\/products\/accupro-72009962-square-end-mill-1-2-in-6-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
