It features a 1\/2 inch diameter with a 0.02 inch corner radius, a 3 inch length of cut, and a 6 inch overall length, making it well suited for deep-pocket and extended-reach applications. The micrograin carbide substrate is coated with TiCN (Titanium Carbonitride) for improved wear resistance and tool life in ferrous and non-ferrous materials. With 4 right-hand spiral flutes and centercutting capability, it handles both plunge and peripheral cutting. This tool is installed and operated by machinists, tool-and-die makers, and CNC programmers working in job shop and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in vertical machining centers, CNC knee mills, and similar machine tool setups where extended reach into deep cavities or tall workpiece features is required. The extra-long length type and 1\/2 inch shank diameter make it compatible with standard ER and end mill holders. The corner radius geometry reduces stress concentration at the cutting edge, extending tool life in slotting, profiling, and finishing passes on steel, stainless, cast iron, and similar materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention in demanding cuts\u003c\/li\u003e\n\u003cli\u003eTiCN coating improves hardness and wear resistance compared to uncoated carbide\u003c\/li\u003e\n\u003cli\u003e0.02 inch corner radius reduces edge chipping and improves surface finish at part corners\u003c\/li\u003e\n\u003cli\u003e4 right-hand spiral flutes with centercutting capability for plunge entry\u003c\/li\u003e\n\u003cli\u003eExtra-long 6 inch overall length with 3 inch length of cut for deep-reach applications\u003c\/li\u003e\n\u003cli\u003eSingle-end design with right-hand cutting direction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard addition for CNC machining centers and manual mills using 1\/2 inch end mill holders or collet chucks accepting a 1\/2 inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by qualified machinists following standard toolholding procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank to the recommended minimum engagement depth in the holder and torque set screws or collet nuts per the holder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut, as excessive runout accelerates edge wear on carbide tooling.\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\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches (1.6250 inches decimal per attribute data)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.02 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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: TiCN\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\u003eLength Type\u003c\/strong\u003e: Extra Long\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\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus or minus 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\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: 12183319\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738724892978,"sku":"12183319","price":255.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d5702321fcb73c1d329c3cbaaf21c1a_baa8a54c-a772-470c-9c1c-712501a85b1c.jpg?v=1788803467","url":"https:\/\/voomisupply.com\/products\/accupro-12183319-corner-radius-end-mill-1-2-in-4-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
