Part of the CoroMill 390 series, it features a 5\/8-inch cutting diameter and a maximum depth of cut of 10.01 mm (0.394 inches). The tool body is constructed from steel and uses a cylindrical shank measuring 5\/8 inch in diameter. With a maximum spindle speed of 31,000 RPM and through-coolant capability, this end mill is suited for high-speed, thermally demanding cuts where chip evacuation and tool life are critical. It accepts standard R390-11.. indexable inserts secured by screw clamping, making insert replacement straightforward in production environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is designed for CNC machining centers used in aerospace, automotive, die-and-mold, and general metalworking operations. The 90-degree lead angle produces true square shoulders, making it well suited for slotting, side milling, and ramping operations. The 2-flute configuration with through-coolant support is appropriate for both roughing and semi-finishing passes. Machinists and CNC operators working with ferrous and non-ferrous materials will find this tool compatible with typical vertical and horizontal machining center setups requiring a 5\/8-inch straight-shank toolholder.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8-inch cutting diameter with a 90-degree lead angle for true square-shoulder milling\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 10.01 mm (0.394 inches) for productive material removal\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design for improved chip evacuation and thermal control at high RPM\u003c\/li\u003e\n  \u003cli\u003eAccepts 2 indexable R390-11.. inserts with screw-clamping retention\u003c\/li\u003e\n  \u003cli\u003eRamping-capable end mill type for versatile toolpath strategies\u003c\/li\u003e\n  \u003cli\u003eSteel tool body with cylindrical shank for rigid, precise toolholder engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to accept R390-11.. series indexable inserts.

Power down and lock out the machine spindle before mounting or changing inserts or the tool body. Use a torque wrench appropriate for insert screws to avoid under- or over-tightening, and verify through-coolant passages are clear before engaging the spindle. Confirm shank engagement depth meets toolholder manufacturer minimums before running at elevated RPM.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 5\/8 inch (0.625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 10.01 mm (0.394 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 144.78 mm (5.7 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch (0.625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 4.325 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 1.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutter Inserts\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Compatibility\u003c\/strong\u003e: R390-11..\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 31,000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Type\u003c\/strong\u003e: Ramping\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Number\u003c\/strong\u003e: RA390-016O16L-11L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroMill 390\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.71 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: 5739309\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51729494180146,"sku":"5739309","price":544.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/23d7517d68e51d64ec7a2e27dd0f9e88.jpg?v=1788705272","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5739309-square-shoulder-end-mill-5-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
