It features a 5\/8 inch diameter, a 1-1\/4 inch length of cut, and a 1\/32 inch (0.0313 inch) corner radius that protects the cutting edge and extends tool life in interrupted cuts. The TiAlN PVD multilayer coating resists heat and wear, making this tool well suited for both roughing and finishing operations. With 4 right-hand helical flutes at a 50-degree helix angle and centercutting capability, it handles full-slot and plunge entries. Licensed HVAC technicians, machinists, and tool-and-die professionals working in production environments are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis end mill is built for cutting steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It fits into standard straight-cylindrical toolholders with a 5\/8 inch shank diameter tolerance h6 and a mill diameter tolerance h9. The extra-long 4-1\/2 inch overall length allows reach into deep pockets, cavities, and contoured features where shorter tools cannot access. It is appropriate for CNC machining centers in both production and job-shop settings where consistent edge integrity and surface finish are required across a range of workpiece materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and edge retention in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD multilayer coating reduces thermal wear and oxidation at elevated cutting temperatures\u003c\/li\u003e\n  \u003cli\u003e1\/32 inch corner radius extends tool life by distributing cutting forces away from a sharp corner\u003c\/li\u003e\n  \u003cli\u003e50-degree high helix angle improves chip evacuation and surface finish\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables plunge milling and ramp entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eExtra-long 4-1\/2 inch OAL provides reach for deep pocket and contour applications\u003c\/li\u003e\n  \u003cli\u003eNormal pitch, single-end, right-hand cut with straight-cylindrical shank for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard straight-cylindrical toolholders accepting a 5\/8 inch shank.

Power down and lock out the spindle before inserting or removing the tool from the toolholder. Ensure the shank is fully seated and the toolholder collet or set screw is torqued to the toolholder manufacturer specification before running. Inspect the corner radius and cutting edges for chips or wear before each setup.\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 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: h9\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inch (1.6250 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.0313 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 50 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4-1\/2 inch (4.5000 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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: Helical\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 Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN PVD Multilayer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\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\u003ePitch\u003c\/strong\u003e: Normal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: RA216\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 1630\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.7 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: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5739990\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51749289066802,"sku":"5739990","price":859.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/470f5f59cd5accb68e89c750e2e797c0_7fa00bcd-3d1d-412c-a6a4-1b69e6b5bf1b.jpg?v=1788904102","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5739990-corner-radius-end-mill-5-8in-4-fl","provider":"Voomi Supply","version":"1.0","type":"link"}
