It features a 1\/2 inch diameter with a 0.02 inch corner radius, four flutes, and an AlTiN coating that improves heat resistance and tool life during high-speed cutting. The extra-long configuration delivers a 3 inch length of cut and a 6 inch overall length, giving machinists extended reach for deep-cavity and shoulder milling operations. The micrograin carbide substrate supports tighter tolerances and harder workpiece materials. This tool is installed and operated by CNC machinists and tool-and-die professionals in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling ferrous metals, hardened steels, and high-temperature alloys where conventional coatings fall short. The single-end, centercutting design allows plunge entry as well as peripheral and slot cuts. The extra-long flute length makes it appropriate for deep-pocket work, tall workpiece profiles, and applications where a standard-length end mill cannot reach. Right-hand cutting and right-hand spiral flute direction are standard for conventional CNC vertical and horizontal machining center setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN coating provides oxidation resistance and extends tool life in dry and semi-dry cutting of ferrous materials\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate supports tight mill diameter tolerance of +0.000000 to -0.002500 inches\u003c\/li\u003e\n\u003cli\u003e0.02 inch corner radius reduces stress concentration at the cutting edge and improves surface finish at part edges\u003c\/li\u003e\n\u003cli\u003eExtra-long 3 inch length of cut (6 inch OAL) enables deep-cavity and extended-reach milling\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eFour-flute, right-hand spiral design balances chip evacuation with surface finish quality\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit tooling option for CNC machining centers and manual mills accepting a 1\/2 inch straight shank in standard ER, side-lock, or shrink-fit toolholders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank to the full recommended engagement depth in the toolholder and torque the retention mechanism per the toolholder manufacturer specifications. Confirm runout with a dial indicator before beginning a cut, as excessive runout accelerates edge wear and can cause premature tool failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\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: 3 inches (2.5000 inches decimal)\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\u003eCorner Radius\u003c\/strong\u003e: 0.0200 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\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\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\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\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\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\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\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.63 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: 12183328\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728469164338,"sku":"12183328","price":236.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/17b45df7b58c7ac907ee22515b4169e1_d5322483-8a3a-488d-a8a6-d24afa35a484.jpg?v=1788691700","url":"https:\/\/voomisupply.com\/products\/accupro-12183328-corner-radius-end-mill-1-2-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
