With a 1\/2 inch mill diameter, a 1-1\/2 inch length of cut, and a 1\/8 inch (0.1250 inch) corner radius, this tool delivers controlled edge geometry that reduces stress concentrations and extends tool life in hardened and abrasive workpiece materials. The 40-degree helix angle promotes efficient chip evacuation, while the AlTiN coating provides thermal resistance and surface hardness at elevated cutting temperatures. The micrograin carbide substrate supports tight tolerances and consistent performance across production runs. This is a single-end, centercutting tool suitable for plunge entry and full-profile milling operations.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling operations in job shops, aerospace, die and mold, and general precision machining environments. The extra-long 6 inch overall length allows reach into deep pockets and cavities where standard-length tools cannot access. Right-hand cut and right-hand flute spiral are standard for conventional CNC vertical and horizontal machining centers. The centercutting geometry supports helical interpolation and direct plunge entry without a pre-drilled pilot hole. Machinists and CNC operators working with ferrous alloys, hardened steels, stainless, and titanium alloys will find this coating and substrate combination appropriate for those materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance in abrasive materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides high thermal hardness and oxidation resistance at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch corner radius reduces tool chipping and workpiece stress risers at milled edges\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes smooth chip flow and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge entry and helical ramping\u003c\/li\u003e\n  \u003cli\u003eExtra-long 6 inch OAL provides reach for deep cavity and pocket milling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide corner radius end mill for CNC machining centers accepting a 1\/2 inch straight shank toolholder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians using a compatible 1\/2 inch collet or end mill holder torqued to the toolholder manufacturer specifications. Ensure the machine spindle is fully stopped and locked before inserting or removing the tool. Inspect the shank and holder bore for chips or contamination before seating the tool, as debris can cause runout that shortens tool life. Follow the cutting tool manufacturer feed and speed recommendations for the specific workpiece material and coating combination.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/2 inches (0.0472 inch decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/8 inch (0.1250 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 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: 40 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\u003c\/strong\u003e: AlTiN\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\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\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002500 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00150 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 12183737\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51755787059506,"sku":"12183737","price":190.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3a08e4b4b74eeedfd4e81c393f42fc95.jpg?v=1788959688","url":"https:\/\/voomisupply.com\/products\/accupro-12183737-corner-radius-end-mill-1-2-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
