With a 5\/16 inch (0.3125 inch) diameter and six flutes, it delivers aggressive material removal while maintaining a fine surface finish. The AlTiN+ coating provides thermal resistance and extended tool life in elevated cutting temperatures. A variable helix angle of 36 and 40 degrees, combined with variable index geometry, reduces chatter and harmonics during cuts. This single-end tool is center-cutting and right-hand cutting with a right-hand helical flute direction. It is sized for use in CNC machining centers and manual mills by machinists and tool-and-die professionals.\u003c\/p\u003e\u003cp\u003eThis end mill is optimized for high-temperature alloys (material code S), including nickel-based superalloys, titanium, and similar difficult-to-machine materials. The straight shank and fractional inch sizing make it compatible with standard collet systems. The 7\/16 inch length of cut and 2 inch overall length suit cavity milling, profiling, and contour work in aerospace, medical, and industrial part manufacturing. It does not feature coolant-through capability or a chipbreaker, and extended reach is not applicable to this configuration.\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-heat resistance and extended tool life\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 rates and improves finish quality\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows plunge entry into workpieces\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand helical flute direction for standard CNC spindle use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with high-temperature alloys (ACCUPRO material code S), including titanium and nickel-based superalloys.

Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank to the minimum recommended engagement depth for the holder type in use. Follow machine tool manufacturer guidelines and applicable shop safety procedures when setting feeds, speeds, and depth of cut for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter (mm)\u003c\/strong\u003e: 7.94 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: 7\/16 inch (0.4375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (mm)\u003c\/strong\u003e: 11.11 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter (mm)\u003c\/strong\u003e: 7.94 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (mm)\u003c\/strong\u003e: 50.8 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\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 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\u003eSingle or Double End\u003c\/strong\u003e: Single\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: 0.07 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: 72056708\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51782801129778,"sku":"72056708","price":79.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_33a90b4d-c7b9-4e59-9346-d47eb20686b6.jpg?v=1789182041","url":"https:\/\/voomisupply.com\/products\/accupro-72056708-ball-end-mill-5-16-inch-6-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
