It features a 0.06 inch corner radius that reduces stress concentration at the cutting edge and extends tool life in aggressive material removal applications. With a 4-inch overall length, a 1\/2 inch diameter, and a 1 inch length of cut, this is a long-series end mill suited for reaching into pockets and stepped features. The TiCN coating provides increased surface hardness and wear resistance compared to uncoated carbide. Machining professionals and tool-and-die shops rely on this geometry for semi-finish and finish passes where edge integrity matters.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in CNC machining centers handling ferrous alloys, hardened steels, stainless, and similar demanding workpiece materials. The single-end, centercutting design supports both peripheral and plunge cuts, making it practical for profiling, slotting, and pocket milling. The 40-degree helix promotes efficient chip evacuation and smooth cutting action. It is well suited to vertical and horizontal machining centers running at production feeds and speeds where coating durability and dimensional consistency are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.06 inch corner radius reduces edge chipping and improves corner strength in milled features\u003c\/li\u003e\n  \u003cli\u003eTiCN coating delivers elevated surface hardness and reduced friction for extended tool life\u003c\/li\u003e\n  \u003cli\u003eSolid micrograin carbide substrate supports precision tolerances and rigidity at depth\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes aggressive chip evacuation and reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eLong-series 4 inch overall length provides reach into deep pockets and stepped workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/2 inch shank end mill compatible with ER collet chucks, end mill holders, and hydraulic toolholders sized for 1\/2 inch straight shanks on CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the controller is in a safe state before changing tooling. Seat the shank fully into the holder to the recommended engagement depth and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator after clamping, as excessive runout accelerates wear on coated carbide end mills and degrades dimensional accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0600 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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute 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: 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\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: 0.1 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: 12183568\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":67581908386098,"sku":"12183568","price":145.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a44a9782eb7691dc0f9c665552c8b238.jpg?v=1790409974","url":"https:\/\/voomisupply.com\/products\/accupro-12183568-corner-radius-end-mill-1-2-in-4-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
