It features a 5\/8 inch diameter with a 0.025 inch corner radius that reduces stress concentration at the cutting edge, extending tool life and improving surface finish on workpiece corners and slots. With 3 right-hand spiral flutes and a bright uncoated finish, this single-end, centercutting tool handles a 7\/8 inch length of cut at a 40-degree helix angle. The micrograin carbide construction provides hardness and wear resistance suited to demanding cutting conditions. Licensed machinists and CNC operators are the primary users of this tooling.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in vertical and horizontal machining centers, CNC mills, and manual knee mills where a corner radius profile is required. It is appropriate for slotting, profiling, and peripheral milling in ferrous and non-ferrous materials. The centercutting geometry allows plunge entry into the workpiece, adding versatility in multi-axis and 3D contouring operations. The 5\/8 inch shank diameter fits standard ER and straight-bore tool holders commonly found in production and job-shop environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.025 inch corner radius reduces edge chipping and improves corner surface finish\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction for high hardness and extended tool life\u003c\/li\u003e\n\u003cli\u003e3 right-hand spiral flutes with 40-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for a wide range of materials including aluminum and non-ferrous alloys\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with 3 inch overall length for reach in standard setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide corner radius end mill for standard 5\/8 inch straight-bore and collet-style tool holders used in CNC and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC tooling technicians. The machine spindle must be fully stopped and locked out before changing tooling. Confirm that the tool holder bore and collet size match the 5\/8 inch shank diameter before seating the end mill. Proper tool runout should be verified with a dial indicator after tightening to ensure accurate cuts and prevent premature tool wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/8 inch (0.8750 inches)\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: 5\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.025 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: +0.000200 \/ -0.000800 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -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\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\u003eMaterial\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: 0.6 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 12176627\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51742581489970,"sku":"12176627","price":162.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cf363aaa2817b44eab47232332bef16e.jpg?v=1788838181","url":"https:\/\/voomisupply.com\/products\/accupro-12176627-corner-radius-end-mill-5-8-in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
