It features a 3\/8 inch diameter with a 0.01 inch corner radius, producing controlled edge breaks and smooth transitions on workpiece corners. The two-flute, right-hand spiral geometry promotes chip evacuation, while the AlTiN coating improves heat resistance and tool life at elevated cutting speeds. With a 7\/8 inch length of cut and 2.5 inch overall length, this single-end, centercutting tool is suited for slotting, profiling, and plunge operations. It is installed and operated by machinists and tool-and-die professionals on CNC milling machines and manual knee mills.\u003c\/p\u003e\u003cp\u003eThis end mill is used in job shops, production machining environments, and toolroom applications where consistent corner geometry is required. The micrograin solid carbide substrate supports tight tolerances and wear resistance on ferrous and non-ferrous materials. Its centercutting design allows direct plunge entry without pre-drilling. The AlTiN coating makes it well suited for dry or semi-dry cutting on alloy steels, stainless steels, cast iron, and hardened materials where thermal load is a concern.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN coating for elevated heat resistance and extended tool life in ferrous machining\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and tight dimensional tolerance\u003c\/li\u003e\n\u003cli\u003e0.01 inch corner radius reduces stress concentration at workpiece corners\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry supports direct plunge milling without pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand spiral flute direction for standard CNC spindle compatibility\u003c\/li\u003e\n\u003cli\u003eSingle-end design with 3\/8 inch shank for direct collet or end mill holder mounting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard 3\/8 inch shank corner radius end mill for use in collet chucks, end mill holders, and shrink-fit toolholders sized for 3\/8 inch straight shanks on CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed by qualified machinists following standard toolroom practices. Ensure the spindle is fully stopped and machine power is locked out before loading or removing the end mill from the holder. Use a properly sized collet or end mill holder and verify runout with a dial indicator before committing to a production setup. Cutting parameters including speed, feed, and depth of cut should be determined based on workpiece material, machine rigidity, and coolant strategy.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.01 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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\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\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\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\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\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 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: 12181423\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51753225978162,"sku":"12181423","price":77.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c7d91bb7b995ae97753a294edaed9daa.jpg?v=1788934105","url":"https:\/\/voomisupply.com\/products\/accupro-12181423-corner-radius-end-mill-3-8-in-2-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
