With a 1\/2 inch cutting diameter, 1 inch length of cut, and a 0.02 inch corner radius, this tool reduces stress concentrations at part corners and extends tool life in demanding applications. The 40-degree helix angle promotes smooth chip evacuation and reduces cutting forces. An AlTiN coating provides high heat resistance and wear protection, making this end mill well suited for dry or semi-dry machining at elevated speeds. Machinists and CNC operators in job shops, aerospace, and die-mold environments will find this a reliable choice for finishing and semi-finishing passes.\u003c\/p\u003e\n\u003cp\u003eThis end mill is used in vertical and horizontal machining centers for slotting, profiling, and contouring operations where a radiused corner is required on the finished workpiece. The single-end, centercutting design allows for plunge entry and versatile toolpath strategies. It is commonly applied in steel, stainless steel, cast iron, and titanium alloys. The 1\/2 inch shank diameter fits standard ER collet chucks, hydraulic chucks, and shrink-fit holders common in production CNC setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.02 inch corner radius reduces corner chipping and stress risers on finished parts\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating delivers high-temperature hardness and oxidation resistance for dry or minimal-coolant machining\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip evacuation and smooth cutting action\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for improved wear resistance and edge retention\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute spiral for use in standard CNC milling spindles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit solid carbide corner radius end mill for standard 1\/2 inch collet, hydraulic, or shrink-fit toolholding systems used in CNC vertical and horizontal machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool changer or spindle lock is engaged before inserting or removing the end mill. Verify the shank is seated to the correct gauge-line depth in the holder and that collet torque specifications for the toolholder manufacturer are followed. Inspect the cutting edges under magnification before use and do not run a chipped or worn 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\/2 inch (0.5000 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch (0.2500 inch decimal flute length per spec)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.02 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inch\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: AlTiN\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute 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\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00150 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\u003eWeight\u003c\/strong\u003e: 0.25 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: 12182608\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51747968418098,"sku":"12182608","price":105.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/11f4b2f7608f08b1063d1a8129c63970.jpg?v=1788887547","url":"https:\/\/voomisupply.com\/products\/accupro-12182608-corner-radius-end-mill-1-2-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
