It accepts two R390-17 series inserts held by screw clamp and is designed for 90-degree shoulder milling, ramping, and general square-shoulder profiling operations. The tool body is constructed from steel and features through-coolant capability for improved chip evacuation and insert life at elevated cutting speeds. With a 1-inch cutting diameter and a maximum depth of cut of 15.7 mm (0.618 inches), it is sized for mid-range roughing and finishing passes in ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for use in CNC machining centers in both production and job-shop environments. It is well suited for applications requiring true 90-degree walls, including face milling, shoulder milling, and ramping entries. The cylindrical shank measures 1 inch in diameter and 5.875 inches in length, making it compatible with standard ER or side-lock toolholders at that bore size. The 8-inch overall length provides clearance for deeper fixture setups. Maximum spindle speed is rated at 12,100 RPM. Licensed machinists, CNC programmers, and toolroom technicians are the primary users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCoroMill 390 platform with 90-degree lead angle for true square-shoulder cuts\u003c\/li\u003e\n  \u003cli\u003eAccepts two R390-17 series indexable inserts secured by screw clamp\u003c\/li\u003e\n  \u003cli\u003eThrough-coolant design aids chip removal and extends insert life\u003c\/li\u003e\n  \u003cli\u003eRamping-capable end mill type for plunge and ramp entry strategies\u003c\/li\u003e\n  \u003cli\u003eMaximum rated spindle speed of 12,100 RPM\u003c\/li\u003e\n  \u003cli\u003eSteel tool body for rigidity and vibration damping in heavy-duty cuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with R390-17 series indexable inserts.

Confirm toolholder bore size and projection length before assembly to avoid runout. Inserts must be seated cleanly and torqued to the insert screw specification published in the SANDVIK COROMANT CoroMill 390 tooling guide — do not estimate torque values. Through-coolant ports should be cleared and pressure-tested before returning the tool to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 15.7 mm (0.618 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 5.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 2.125 inches\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: R390-17\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: 12,100\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: RA390-025O25L-17L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.03 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: 5739326\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51750708937010,"sku":"5739326","price":590.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/23d7517d68e51d64ec7a2e27dd0f9e88_4e1e817a-a34e-4675-82c9-10842e182f8b.jpg?v=1788918800","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5739326-square-shoulder-end-mill-1-in","provider":"Voomi Supply","version":"1.0","type":"link"}
