Built to Series HS standards, it features a 3\/4-inch diameter, a 1-inch length of cut, and a 0.060-inch corner radius that blends floor and wall transitions to reduce stress concentrations in the workpiece. The AlCrTiN coating delivers high heat resistance and extended tool life, particularly in ferrous alloys and hardened steels. With five flutes, a 38-degree helix angle, and variable index geometry, this end mill balances chip evacuation with surface finish quality. It is center-cutting and right-hand cutting with right-hand flute direction.\u003c\/p\u003e\u003cp\u003eThis end mill suits CNC machining centers running side milling, slotting, and finishing passes where corner integrity and tool longevity are priorities. The corner radius geometry is well-suited for die and mold work, aerospace components, and general precision part machining where sharp internal corners are not permissible. The 3\/4-inch shank mates directly to standard ER or end mill holders of the same bore. Overall length is 3 inches, keeping rigidity high in setups where tool deflection is a concern.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.060-inch corner radius reduces stress risers at workpiece transitions\u003c\/li\u003e\n\u003cli\u003eAlCrTiN coating for high-temperature wear resistance in ferrous and hard materials\u003c\/li\u003e\n\u003cli\u003e5-flute, variable index design balances material removal rate and surface finish\u003c\/li\u003e\n\u003cli\u003e38-degree helix angle promotes efficient chip flow and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable — suitable for plunge entry and ramp entry operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use end mill for CNC machining centers and manual mills accepting a 3\/4-inch shank end mill holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine in an e-stop or lockout\/tagout state. Use a properly sized collet or end mill holder torqued to the machine tool manufacturer's specification — do not overtighten or use worn holders, as runout directly affects tool life and surface finish. Inspect the cutting edges and coating condition before each use; chipped or worn edges on carbide end mills should not be run. Follow the tooling manufacturer's recommended speeds and feeds for the specific workpiece material and coating type.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\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 (76.2 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (19.05 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.060 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: AlCrTiN\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\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.001000 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 311773\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51747926475058,"sku":"311773","price":331.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1e8ea3a5c75e71bc32a6d5066605f437.jpg?v=1788887171","url":"https:\/\/voomisupply.com\/products\/accupro-311773-corner-radius-end-mill-3-4-in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
