With a 5\/16 inch (0.3125 inch) mill diameter and six flutes, it delivers smooth cutting action and efficient chip evacuation. The AlTiN+ coating provides elevated heat resistance and extended tool life when working in high-temperature alloys and other abrasive materials. A 0.0200 inch corner radius reduces stress concentration at the cutting edge, helping to prevent chipping during aggressive cuts. This tool is intended for use by machinists and tooling professionals in precision machining environments.\u003c\/p\u003e\u003cp\u003eThis end mill is built for milling high-temperature alloys (material code S), including nickel-based superalloys, titanium, and similar hard-to-machine materials common in aerospace, medical, and power generation work. The 1 inch length of cut and 3 inch overall length suit a range of roughing and finishing passes. Variable helix and variable index geometry reduce harmonic vibration during cutting, which is especially useful in long-reach or tight-tolerance setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN+ coating for high heat resistance and extended tool life in abrasive materials\u003c\/li\u003e\n\u003cli\u003eVariable helix and variable index design reduces chatter and improves surface finish\u003c\/li\u003e\n\u003cli\u003e0.0200 inch corner radius protects the cutting edge and reduces stress risers\u003c\/li\u003e\n\u003cli\u003eSix-flute configuration supports higher feed rates and improved finish on ferrous and exotic alloys\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows plunge entry into workpiece\u003c\/li\u003e\n\u003cli\u003eSingle-end, right-hand cut with right-hand flute direction for standard CNC mill setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide end mill replacement for 5\/16 inch shank toolholders used in CNC machining centers and manual mills requiring a right-hand, single-end corner radius tool.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or tooling technicians. Ensure the spindle is fully stopped and the machine is in a safe lockout state before changing tooling. Seat the 5\/16 inch shank fully into a matching collet or end mill holder and torque the retention hardware per the toolholder manufacturer's specifications. Confirm runout with a dial indicator before beginning a cut, as excess runout accelerates wear on carbide tooling.\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 inch \/ 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\u003eLength of Cut\u003c\/strong\u003e: 1 inch (25.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches (76.20 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inch (0.3125 inch \/ 7.94 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0200 inch (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\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\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 (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: 0.11 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: 72066624\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51753199501618,"sku":"72066624","price":84.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_d2e48a5c-a9b5-4d33-829d-d9a5debdb1bc.jpg?v=1788933804","url":"https:\/\/voomisupply.com\/products\/accupro-72066624-corner-radius-end-mill-5-16-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
