With a 5\/16-inch (0.3125 inches) mill diameter and six flutes, it delivers smooth cutting action and efficient chip evacuation. The AlTiN+ coating provides thermal resistance and extended tool life in high-temperature alloy applications. Variable helix and variable index geometry reduce harmonics and chatter during aggressive cuts. This tool is single-end, right-hand cut, and center-cutting, making it suitable for both plunge and peripheral milling operations. Machinists and tool-and-die professionals select this end mill for tight-tolerance work in aerospace, defense, and energy sector components.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling high-temperature alloys (Material Code: S), including nickel-based superalloys, titanium, and similar difficult-to-machine materials. Typical applications include profiling, slotting, and contouring in CNC machining centers. The 3\/4-inch length of cut and 2-1\/2-inch overall length make it appropriate for medium-depth passes in both roughing and finishing operations. The 0.0200-inch corner radius adds edge strength and reduces the risk of chipping at the cutting edge, which is critical when working in tough materials with high cutting forces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard and high-temp alloys\u003c\/li\u003e\n  \u003cli\u003eAlTiN+ coating for elevated thermal resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003eVariable helix and variable index geometry reduce vibration and chatter\u003c\/li\u003e\n  \u003cli\u003e0.0200-inch corner radius protects the cutting edge and improves surface finish\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting design allows direct plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eSix-flute configuration provides higher feed rates and superior finish quality\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers with standard straight-shank toolholders accepting a 5\/16-inch (0.3125-inch) shank diameter.

Ensure the toolholder is clean and within runout tolerance before seating the shank to the correct insertion depth. Verify spindle speed, feed rate, and depth of cut parameters are set for solid carbide tooling in high-temperature alloy material before running. Do not use this tool on manual mills without confirming the machine has sufficient rigidity and spindle precision for carbide end mills.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches (2.5000 inches)\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\u003eCorner Radius\u003c\/strong\u003e: 0.0200 inches (0.51 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\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\u003eHelix Style\u003c\/strong\u003e: Variable\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\u003eExtended Reach\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\u003eWeight\u003c\/strong\u003e: 0.09 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 72064843\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51733570650418,"sku":"72064843","price":69.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_0e221d23-c55c-4095-a65e-8c3e4e5187b9.jpg?v=1788756448","url":"https:\/\/voomisupply.com\/products\/accupro-72064843-corner-radius-end-mill-5-16-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
