Built from micrograin solid carbide and finished with an AlTiN (Aluminum Titanium Nitride) coating, this tool delivers high heat resistance and extended tool life in ferrous and hardened materials. The corner radius measures 0.015 inches, reducing stress concentration at the cutting edge and improving surface finish in profiling and contouring passes. It carries a 1\/2 inch cutting diameter, a 1 inch length of cut, and a 3 inch overall length. Installation and use are handled by machinists and CNC operators working in job shops, tool rooms, and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling operations requiring a controlled corner radius on finished part edges. The single-end, centercutting design supports both plunge and peripheral cutting. The right-hand flute direction and right-hand cutting orientation make it compatible with standard CNC machining centers and manual knee mills. The 3-flute configuration balances chip evacuation with surface finish, making it a practical choice for slotting, profiling, and pocketing in steel, stainless steel, cast iron, and similar materials where AlTiN coatings perform well.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.015 inch corner radius reduces edge chipping and improves part surface finish\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides high-temperature resistance and extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003e3-flute spiral geometry balances chip clearance with finish quality\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle compatibility\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 standard 1\/2 inch collet or end mill holders on CNC machining centers and manual mills requiring a corner radius cutting tool.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed and operated by machinists and CNC programmers. Secure the 1\/2 inch shank in a properly sized collet or end mill holder, ensuring the holder is clean and free of debris before tightening. Confirm spindle speed and feed rate are set according to the material being cut and the tool manufacturer guidelines for AlTiN-coated carbide tooling. Do not exceed the rated length of cut to avoid deflection or tool breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\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: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 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\u003eWeight\u003c\/strong\u003e: 0.28 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: 12182082\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738710802738,"sku":"12182082","price":126.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/04f09bd391ba4fad574cca95f9f0d88f.jpg?v=1788803205","url":"https:\/\/voomisupply.com\/products\/accupro-12182082-corner-radius-end-mill-1-2-in-3-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
