It features a 1\/8 inch diameter with a 0.03 inch corner radius and a TiCN (Titanium Carbonitride) coating that increases surface hardness and wear resistance for extended tool life. The 2-flute, single-end geometry with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Micrograin carbide construction provides the rigidity and edge retention needed for tight-tolerance work on hardened steels, stainless, and other demanding materials. This end mill is installed and operated by machinists, tool-and-die makers, and CNC programmers in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for finishing and semi-finishing passes where a radiused corner profile is required to reduce stress concentrations or meet part geometry specifications. The centercutting design allows plunge entry, making it useful for slot milling, pocket milling, and contour operations on vertical machining centers and CNC mills. The right-hand flute direction and right-hand cutting orientation are standard for conventional CNC spindle setups. With a 1\/2 inch length of cut and 1-1\/2 inch overall length, it is well matched to shallow-depth work in confined features and thin-wall components.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiCN coating provides increased hardness and wear resistance versus uncoated carbide\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate supports tight tolerances and sharp edge retention\u003c\/li\u003e\n  \u003cli\u003e0.03 inch corner radius reduces corner chipping and meets radiused-fillet part requirements\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes chip flow and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eSingle-end construction with right-hand cut and right-hand spiral flutes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use end mill compatible with standard 1\/8 inch collets and toolholders on CNC vertical machining centers, manual knee mills, and die-sinking setups requiring a corner radius end mill geometry.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or CNC operator. Secure the shank in a clean, properly sized 1\/8 inch collet or end mill holder, torquing to the toolholder manufacturer specification to prevent pullout. Verify runout with a dial indicator before beginning a production run. Always spin the spindle down to a complete stop before changing or measuring the tool.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0300 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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\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\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\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00150 inches\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\u003eWeight\u003c\/strong\u003e: 0.04 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: 12181264\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51740602138930,"sku":"12181264","price":30.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a3218100b70f626ee4e511d7d206af1.jpg?v=1788826134","url":"https:\/\/voomisupply.com\/products\/accupro-12181264-corner-radius-end-mill-1-8-in-2-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
