It features a 5\/8 inch diameter with a 0.045 inch corner radius, a 1-1\/4 inch length of cut, and a 3-1\/2 inch overall length. The three-flute, right-hand spiral geometry is paired with an AlTiN (aluminum titanium nitride) coating, which provides heat resistance and extended tool life in ferrous and hardened materials. Micrograin carbide construction adds edge retention and rigidity. This end mill is center-cutting and single-end, making it suitable for plunge entry and side milling in a single setup.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC machining centers and manual mills for profiling, slotting, and contouring operations where a radiused corner is required to reduce stress concentrations or meet part drawing callouts. The AlTiN coating makes it well suited for dry or semi-dry cutting of alloy steels, stainless steels, cast iron, and hardened materials. It is installed by machinists and tool-and-die professionals in job shops, production facilities, and maintenance machining environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/8 inch mill diameter with 0.045 inch corner radius for reduced stress at part edges\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for heat resistance and extended tool life in ferrous and hardened materials\u003c\/li\u003e\n\u003cli\u003eThree-flute, right-hand spiral design for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with 5\/8 inch shank diameter for standard ER and side-lock holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting a 5\/8 inch shank end mill holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed with the machine in a full stop, lockout state. Secure the 5\/8 inch shank in a properly sized collet or side-lock holder and torque the retention hardware to the holder manufacturer's specification. Inspect the tool shank and holder bore for chips or contamination before seating. Verify runout with a dial indicator before the first cut, as excessive runout will reduce tool life and surface finish quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inches (0.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inches (2.0000 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.045 inches\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\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\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\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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: 0.5 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: 12182115\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51755356356914,"sku":"12182115","price":188.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7784cc2cafe9e33eca36c61715f1085f.jpg?v=1788954093","url":"https:\/\/voomisupply.com\/products\/accupro-12182115-corner-radius-end-mill-5-8-in-3-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
