With a 1\/2 inch cutting diameter and a 0.02 inch corner radius, it produces controlled edge breaks and radius profiles on ferrous and non-ferrous workpieces. Seven flutes and a 37-degree helix angle promote efficient chip evacuation and surface finish quality at elevated feed rates. The AlTiN coating extends tool life in high-heat cutting environments including hardened steels and stainless alloys. Machinists and CNC operators in job shops, aerospace, and general precision machining install this tool in standard 1\/2 inch toolholders.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for side milling, slotting, and profiling operations where a corner radius is required to reduce stress concentrations at part edges. The centercutting geometry allows plunge entry, and the right-hand spiral flute direction is compatible with conventional CNC machining center setups. With a 1-1\/4 inch length of cut and a 3 inch overall length, it handles moderate-depth cavities and contoured profiles in production and prototype environments alike. The variable index flute spacing helps suppress chatter during aggressive cuts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.02 inch corner radius for consistent edge breaking and radius profiling\u003c\/li\u003e\n\u003cli\u003e7-flute geometry supports high feed rates and improved surface finish\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides oxidation resistance and extended tool life in high-temperature cuts\u003c\/li\u003e\n\u003cli\u003e37-degree helix angle promotes smooth chip flow and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eVariable index flute spacing reduces harmonic chatter during heavy milling passes\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate delivers rigidity and wear resistance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling choice for CNC machining centers and manual mills using 1\/2 inch collets, end mill holders, or hydraulic chucks requiring a single-end corner radius end mill.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Ensure the spindle is fully powered down and the machine is in an e-stop or lockout state before changing tooling. Seat the 1\/2 inch shank fully into the holder and torque the retention mechanism per the toolholder manufacturer specification. Verify runout with a dial indicator before beginning the cut cycle, and confirm feed and speed parameters match the workpiece material and depth of cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.020 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.002500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00150 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.307 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: 12178711\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51750192283954,"sku":"12178711","price":128.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/786a81714161e31a4b602a9258e29ae9.jpg?v=1788914225","url":"https:\/\/voomisupply.com\/products\/accupro-12178711-corner-radius-end-mill-1-2-in-7-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
