It carries the ANSI\/ISO designation R390-17 04 08E-ML 2040 and features a multilayer CVD coating of TiCrN, Al2O3, and TiN for extended tool life and heat resistance. The insert has a parallelogram shape with a positive rake angle and a corner-rounded cutting edge, offering two usable cutting edges per insert. It measures 0.6181 inches in length, 0.3780 inches in inscribed circle diameter, and 0.1875 inches thick, with a corner radius of 0.0315 inches.\u003c\/p\u003e\u003cp\u003eThis insert is suited for machining steel, stainless steel, superalloys, and titanium, corresponding to material grade designations P45, M40, and S30. It is intended for use in the R390 cutter series and is appropriate for both roughing and semi-finishing passes. The ML chip breaker geometry helps manage chip control across these demanding workpiece materials. The maximum depth of cut is 0.6181 inches (15.70 mm). Typical applications include aerospace component machining, general job shop milling, and production environments where consistent insert performance across difficult alloys is required. The insert is held in place by a screw clamping method.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with CVD-applied TiCrN, Al2O3, and TiN multilayer coating for thermal and wear resistance\u003c\/li\u003e\n\u003cli\u003eR390 series designation with insert size code 170408 and ANSI\/ISO code R390-17 04 08E-ML 2040\u003c\/li\u003e\n\u003cli\u003eParallelogram shape, right-hand cut, positive rake, corner-rounded edge with 0.0315-inch corner radius\u003c\/li\u003e\n\u003cli\u003eTwo cutting edges per single-sided insert for cost-effective tool management\u003c\/li\u003e\n\u003cli\u003eML chip breaker geometry suited for steel, stainless steel, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.6181 inches (15.70 mm)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with the Sandvik Coromant R390 cutter series.

The machine spindle must be fully stopped and the tool secured before seating or replacing inserts. Inspect the insert pocket and clamping screw for wear or debris before installing a new insert. Follow the toolholder manufacturer torque guidance for the clamping screw to avoid seat damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: R390\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Parallelogram\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 2040\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P45; M40; S30\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCrN, Al2O3, TiN (CVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Corner Rounded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: ML\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 170408\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI\/ISO Code\u003c\/strong\u003e: R390-17 04 08E-ML 2040\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.6181 inches (15.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle Diameter\u003c\/strong\u003e: 0.3780 inches (9.60 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 inches (4.76 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches (0.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1614 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.6181 inches (15.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSided\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: R390\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 5745604\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51755082383666,"sku":"5745604","price":579.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2ab91d54c657f8d2460e90f55358be6e_1dc661c4-1ec9-4901-b768-0165effd3303.jpg?v=1788950944","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5745604-milling-insert-2040-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
