With a 3\/8 inch (0.3750 inch) mill diameter and 6 helical flutes, it delivers smooth cutting action and efficient chip evacuation. The AlTiN+ coating provides thermal resistance and wear protection, making it well suited for cutting high-temperature alloys and other difficult-to-machine materials. The variable helix and variable index geometry reduce chatter and vibration during aggressive cuts, improving surface finish and tool life. This is a single-end, centercutting tool with right-hand cut and right-hand flute direction.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for CNC machining centers and manual milling machines used in aerospace, defense, and industrial manufacturing applications where high-temp alloy workpieces are common. It is part of the ACCUPRO HS series, which targets shops running difficult materials that demand coated solid carbide tooling. Machinists and tool-and-die professionals specify this tool for profiling, contouring, slotting, and plunging operations in nickel-based superalloys, titanium, and similar S-code materials.\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 for high-temperature performance and extended tool life\u003c\/li\u003e\n\u003cli\u003eVariable helix (36 and 40 degrees) and variable index geometry to reduce chatter\u003c\/li\u003e\n\u003cli\u003e6-flute design for high feed rates and improved surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003eSingle-end, straight shank with 3\/8 inch shank diameter matching mill diameter\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and direct-fit tooling option for CNC milling applications requiring a 3\/8 inch straight shank ball end mill in fractional inch tooling systems.

Ensure the tool holder and spindle are clean and free of debris before seating the tool. Confirm runout with a dial indicator before production cuts, as excessive runout accelerates wear on carbide tooling. Follow the machine manufacturer and tooling supplier recommended speeds and feeds for the specific workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (mm)\u003c\/strong\u003e: 9.53 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: 2.0000 inches (50.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3750 inches (9.53 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\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\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\u003eShank Type\u003c\/strong\u003e: Straight\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\u003eChipbreaker\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: 0.21 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: 72080385\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51753038414130,"sku":"72080385","price":111.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_3cb85bc3-3012-4e41-9b48-a4d68a0a2095.jpg?v=1788932335","url":"https:\/\/voomisupply.com\/products\/accupro-72080385-ball-end-mill-3-8-in-6-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
