It features a 1 inch mill diameter, a 3 inch length of cut, and a 1\/8 inch (0.1250 inch) corner radius that reduces stress concentration at the cutting edge and extends tool life. The 40-degree helix angle promotes smooth chip evacuation and reduces cutting forces. An AlTiN coating provides thermal resistance for demanding dry or semi-dry machining conditions. This tool is single-end, centercutting, and intended for use on CNC machining centers by skilled machinists or tool-and-die professionals.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slotting, profiling, and pocket milling operations where a radiused corner is required to meet part geometry or improve tool durability. The extra-long overall length of 6 inches accommodates deep-pocket and extended-reach applications common in mold making, die work, and aerospace component machining. The right-hand flute direction and right-hand cutting geometry are standard for conventional CNC spindle configurations. It is packaged as a single unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1 inch mill diameter with mill diameter tolerance of +0.000000 to -0.002500 inches for precise fit and repeatable results\u003c\/li\u003e\n\u003cli\u003e1\/8 inch corner radius (0.1250 inch) with corner radius tolerance of 0.00150 inches\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for high-temperature resistance and extended tool life in ferrous and hardened materials\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip evacuation and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eSolid carbide micrograin construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eExtra-long 6 inch overall length for deep-pocket and extended-reach applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement-style solid carbide corner radius end mill for standard 1 inch shank tool holders used on CNC vertical and horizontal machining centers requiring right-hand cutting, single-end geometry.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis end mill is installed by a machinist into a compatible 1 inch bore tool holder such as a collet chuck, end mill holder, or hydraulic chuck on a CNC machining center. Ensure the shank is fully seated and the tool holder is torqued to the machine manufacturer's specification before running. Verify runout at the tool tip before beginning a production cut. Always follow shop-floor lockout procedures when changing tooling in a live spindle.\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.1250 inches (1\/8 inch)\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\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\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\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\u003eWeight\u003c\/strong\u003e: 2 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: 12183179\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727508275506,"sku":"12183179","price":754.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a1c3dbc43ed21a4cd9dd85529fe3dc14.jpg?v=1788678686","url":"https:\/\/voomisupply.com\/products\/accupro-12183179-corner-radius-end-mill-1in-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
