It measures 5\/8 inch in diameter with a 0.025 inch corner radius that reduces stress concentrations at the cutting edge and produces a controlled fillet on machined workpieces. The 7\/8 inch length of cut (LOC) and 3-flute right-hand spiral geometry balance chip evacuation with wall finish quality. Overall length is 3 inches. This end mill is installed and operated by machinists and CNC programmers in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis tool is suited for milling steel, stainless steel, cast iron, and high-temperature alloys where an AlTiN coating provides thermal resistance and hardness. The centercutting design allows plunge entry into the workpiece, making it practical for pocketing, slotting, and profiling operations. The 5\/8 inch shank diameter matches standard ER collet chucks, shrink-fit holders, and milling chucks common in vertical and horizontal machining centers. It is appropriate for both roughing and semi-finishing passes depending on depth of cut and material hardness.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating extends tool life in dry and high-speed machining applications\u003c\/li\u003e\n  \u003cli\u003e0.025 inch corner radius reduces edge chipping and produces consistent fillets\u003c\/li\u003e\n  \u003cli\u003e3-flute right-hand spiral geometry balances chip clearance and surface finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting design supports direct plunge entry for pocketing operations\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes smooth cutting action and reduced cutting forces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 5\/8 inch ER collet chucks, shrink-fit holders, or milling chucks on CNC vertical and horizontal machining centers that accept a 5\/8 inch shank diameter end mill.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes must be performed with the machine spindle fully stopped and the control in a safe state per shop lockout\/tagout procedures. Seat the shank fully into the holder to the recommended gauge depth before torquing the retention mechanism to the holder manufacturer specification. Inspect the corner radius and cutting edges for chipping or coating delamination before each use. Refer to the tool manufacturer feed and speed charts and the machining center operator manual for starting parameters.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 7\/8 inch (0.8750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.025 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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\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 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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0002 to -0.0008 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\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.0015 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.6 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: 12176628\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739439104306,"sku":"12176628","price":209.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6db82de34f9544f0857eb87749d5014e.jpg?v=1788814594","url":"https:\/\/voomisupply.com\/products\/accupro-12176628-corner-radius-end-mill-5-8-in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
