With a 3\/4-inch mill diameter, six flutes, and an AlTiN+ coating, this tool is built for machining high-temperature alloys and other hard-to-cut workpiece materials. The ball nose geometry enables contouring, profiling, and 3D surface work where a flat end mill cannot reach. Variable helix and variable index geometry reduce chatter and harmonic vibration, improving surface finish and tool life. It is used by machinists and tool-and-die professionals on CNC milling centers in aerospace, defense, and precision manufacturing environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for single-end use in high-temp alloy applications, designated by workpiece material code S. The 1.25-inch length of cut, 4-inch overall length, and straight 3\/4-inch shank make it compatible with standard ER and end mill holders on vertical and horizontal machining centers. The right-hand cutting and right-hand flute direction are standard for conventional CNC milling spindles. Center-cutting capability allows direct plunge entry. The HS series designation indicates a high-performance geometry targeting difficult alloys at elevated cutting speeds.\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 improves heat resistance and extends tool life in high-temp alloys\u003c\/li\u003e\n\u003cli\u003eVariable helix (36 and 40 degrees) and variable index reduce vibration and chatter\u003c\/li\u003e\n\u003cli\u003eSix-flute design increases feed rate potential and improves surface finish\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003eBall nose profile suited for 3D contouring and profiling operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard straight-shank end mill holders and ER collet chucks accepting a 3\/4-inch shank diameter.

Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Verify runout with a dial indicator after seating the tool to confirm proper holder engagement. Follow the tool manufacturer and machine builder guidelines for speeds, feeds, and depth of cut when programming for high-temp alloy applications.\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\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: 1.2500 inches (31.75 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: 4.0000 inches (101.60 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\u003eFlute Type\u003c\/strong\u003e: Helical\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\u003eCenter Cutting\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 (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: 0.77 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: 72038482\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729291641138,"sku":"72038482","price":352.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_c7cf7464-c573-428a-81eb-4114b7f05d39.jpg?v=1788702509","url":"https:\/\/voomisupply.com\/products\/accupro-72038482-ball-end-mill-3-4-inch-6-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
