It features a 1\/4 inch mill diameter, a 3\/4 inch length of cut, and a 0.03 inch corner radius that reduces stress concentrations at the tool tip and extends part life. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. A TiCN coating increases surface hardness and wear resistance, making this end mill well suited for harder workpiece materials. The 2-flute configuration is ideal for slotting and profiling in materials where chip clearance is a priority. This tool is installed and used by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is commonly used in CNC machining centers and manual milling machines for slotting, profiling, and contouring operations in ferrous and non-ferrous metals. Its single-end, centercutting design allows it to plunge directly into material, expanding its range of tool paths. The right-hand flute direction and right-hand cutting orientation are standard for conventional milling setups. The micrograin carbide substrate provides a fine grain structure that supports sharp cutting edges and dimensional consistency across a production run.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.03 inch corner radius reduces edge chipping and stress risers on finished parts\u003c\/li\u003e\n  \u003cli\u003eTiCN coating improves wear resistance and performance in harder materials\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes chip evacuation and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate delivers consistent edge sharpness and tool life\u003c\/li\u003e\n  \u003cli\u003eSingle-end, 2-flute configuration optimized for slotting and profiling applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard shank end mill with a 1\/4 inch shank diameter, compatible with ER collet chucks, end mill holders, and milling machine spindles accepting 1\/4 inch round shanks in CNC and manual milling setups.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists using a collet chuck or end mill holder sized to the 1\/4 inch shank diameter. Ensure the spindle and machine are fully powered down and locked out before changing tooling. Secure the shank to the full recommended engagement depth in the holder to minimize runout and prevent pullout during cutting. Inspect the collet or holder for wear before use, as excessive runout will reduce tool life and surface finish quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 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 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 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\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\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus or minus 0.0015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0025 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: 0.12 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: 12181341\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51740809462066,"sku":"12181341","price":49.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ad95099ac3cdbd2a62f3a6374c947e22.jpg?v=1788827542","url":"https:\/\/voomisupply.com\/products\/accupro-12181341-corner-radius-end-mill-1-4-in-2-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
