With a 1 inch cutting diameter, 1.75 inches length of cut, and a 0.06 inch corner radius, this single-end tool delivers controlled edge geometry that reduces stress concentrations and extends tool life in hardened and abrasive workpiece materials. The AlTiN coating provides high-temperature resistance and improved wear performance, making it well suited for dry or semi-dry machining of ferrous alloys, stainless steels, and hardened steels. This tool is installed and operated by machinists and CNC programmers working in precision machining shops.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual milling machines where corner radius profiles are required in pockets, slots, or contoured surfaces. The centercutting design allows for plunge entry, giving operators flexibility in toolpath strategies. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action across a range of ferrous and non-ferrous materials. The 1 inch shank diameter ensures rigid tool holding in standard milling chucks and collet systems sized for that shank.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1 inch cutting diameter with 1.75 inches length of cut for deep pocket and slot applications\u003c\/li\u003e\n  \u003cli\u003e0.06 inch corner radius reduces stress risers and improves part surface finish at floor-to-wall transitions\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides high heat resistance for extended tool life in ferrous and hardened materials\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate delivers rigidity and wear resistance across demanding materials\u003c\/li\u003e\n  \u003cli\u003e40-degree right-hand helix promotes aggressive chip evacuation and smooth cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003e2-flute configuration balances chip clearance with edge strength in slotting and side milling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tool for CNC machining centers and manual milling machines accepting a 1 inch shank diameter end mill holder, collet chuck, or hydraulic chuck.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed by qualified machinists or CNC setup technicians. Power down and lock out the spindle before inserting or removing the end mill from its holder. Ensure the shank is fully seated to the minimum insertion depth recommended by the tool holder manufacturer and that all set screws or collet nuts are torqued according to the holder manufacturer specifications. Verify spindle speed and feed rate parameters against the tool manufacturer cutting data before engaging the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.06 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus or minus 0.0015 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002500 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inch\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\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\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\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: 12176842\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739501396274,"sku":"12176842","price":523.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b434d05aadfa4be69972585d459d195_00bde4fe-6601-470c-a599-c2606af2f067.jpg?v=1788815314","url":"https:\/\/voomisupply.com\/products\/accupro-12176842-corner-radius-end-mill-1-in-2-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
