It features a 1 inch diameter with a 0.015 inch corner radius and a 2.25 inch length of cut, making it well suited for profiling, slotting, and peripheral milling operations where edge protection and extended tool life are priorities. The TiCN (Titanium Carbonitride) coating increases surface hardness and reduces friction, supporting higher cutting speeds and improved wear resistance. Weighing 1.89 pounds, this is a single-end, centercutting tool with a right-hand flute direction and right-hand cutting action.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC machining centers and manual mills across job shops, tool and die operations, aerospace component manufacturing, and general metalworking applications. The long-reach geometry, 5 inch overall length with a 1 inch shank diameter, allows access to deeper pockets and cavities where standard-length tools cannot reach. The 4-flute, spiral flute design provides a good balance of chip evacuation and surface finish quality. It is appropriate for ferrous and non-ferrous materials where TiCN coatings provide a performance advantage.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eTiCN coating improves hardness and extends tool life in high-speed applications\u003c\/li\u003e\n\u003cli\u003e0.015 inch corner radius protects cutting edge and reduces chipping at workpiece corners\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge milling operations\u003c\/li\u003e\n\u003cli\u003eLong-length geometry (5 inch OAL) provides extended reach into deep pockets\u003c\/li\u003e\n\u003cli\u003eRight-hand, 4-flute spiral configuration balances chip evacuation and finish quality\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide corner radius end mill compatible with standard 1 inch tool holders, collet chucks, and shrink-fit holders used on CNC machining centers and milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed by a qualified machinist with the spindle fully stopped and the machine in a safe, locked-out state. Ensure the shank is clean and seated fully in the tool holder before torquing to the holder manufacturer specifications. Verify runout after installation using a dial indicator before beginning a cut. Follow applicable shop safety standards and machine manufacturer guidelines when selecting speeds and feeds for this tool geometry and coating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\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 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\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: Long\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: +0.000000 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: 1.89 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: 12182979\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51747519103282,"sku":"12182979","price":595.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/266c4ed1cdb2ee1132e98e5730e58b03.jpg?v=1788881782","url":"https:\/\/voomisupply.com\/products\/accupro-12182979-corner-radius-end-mill-1in-4-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
