With a 1\/2 inch mill diameter and a 5-flute configuration, it delivers efficient chip evacuation and smooth surface finishes on hardened materials. The 38-degree variable-index helix geometry reduces harmonics during cutting, while the AlCrTiN coating provides heat resistance and extended tool life in high-temperature applications. This end mill features a corner radius of 0.030 inches, which strengthens the cutting edge and reduces chipping compared to a sharp corner profile. It is a centercutting, single-end tool suited for plunge, slot, and peripheral milling operations across a range of ferrous and non-ferrous materials. Installation and use are performed by machining professionals operating CNC or manual milling equipment.\u003c\/p\u003e\n\u003cp\u003eThe 312237 is built for extended-reach applications, with an overall length of 6 inches and a reach length of 4.125 inches, making it well suited for deep-cavity, pocket, and mold-and-die work where standard-reach tools cannot access the workpiece. The neck diameter of 0.475 inches provides clearance relief in confined areas. The 5\/8 inch length of cut and 1\/2 inch shank diameter allow secure tool holding in standard ER or side-lock collet chucks. Right-hand cutting and right-hand flute direction make this tool compatible with conventional CNC spindle configurations. Micrograin carbide substrate supports the demands of high-speed, high-feed toolpaths common in aerospace, automotive, and precision die work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAlCrTiN coating for extended tool life and heat resistance in high-speed applications\u003c\/li\u003e\n  \u003cli\u003e5-flute, variable-index geometry reduces chatter and improves surface finish\u003c\/li\u003e\n  \u003cli\u003e0.030 inch corner radius strengthens cutting edge and reduces chipping\u003c\/li\u003e\n  \u003cli\u003eExtended reach of 4.125 inches with a reduced neck for deep-cavity access\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for rigidity and wear resistance\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 and manual mills using 1\/2 inch shank tool holders.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes should be performed by qualified machinists with the spindle fully stopped and the machine in a locked-out state. Ensure the tool holder is clean and free of debris before seating the 1\/2 inch shank to the correct insertion depth. Verify runout with a dial indicator after clamping, as excessive runout will accelerate wear on a 5-flute extended-reach tool. Follow the cutting tool manufacturer and machine builder guidelines for speeds, feeds, and coolant application appropriate to the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.500 inches\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: 0.625 inches\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: 0.500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.475 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 4.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.030 inches\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\u003c\/strong\u003e: AlCrTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003eVariable Index\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\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus 0.000000 \/ minus 0.001000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 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: 312237\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51751297286450,"sku":"312237","price":225.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/408483109b000e1d7d691b1ee97ad055.jpg?v=1788922722","url":"https:\/\/voomisupply.com\/products\/accupro-312237-corner-radius-end-mill-1-2-inch-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
