It features a parallelogram shape with a 90-degree included angle, positive 5-degree rake geometry, and a corner-rounded cutting edge style. The insert measures 11.00 mm in inscribed circle diameter and 6.33 mm thick, with a 0.80 mm corner radius. A CVD-applied multilayer coating of TiCrN, Al2O3, and TiN provides thermal and wear resistance across demanding cutting applications. Licensed machinists and toolroom technicians are the primary installers and operators.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for face and shoulder milling of steel, stainless steel, superalloys, and titanium in both production and job-shop environments. It carries material grade designations P45, M40, and S30, making it appropriate for a broad range of workpiece hardness and toughness levels. The ML chip breaker geometry is optimized for light to medium depth cuts, with a maximum depth of cut rated at 16.00 mm. It mounts via screw holding in compatible R390 and M-40 cutter bodies.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiCrN, Al2O3, TiN for high-temperature and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle of 5 degrees reduces cutting forces on difficult materials\u003c\/li\u003e\n  \u003cli\u003eML chip breaker optimized for light-to-medium depths of cut up to 16.00 mm\u003c\/li\u003e\n  \u003cli\u003eSingle-sided, right-hand insert with 2 cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eCorner-rounded cutting edge style extends tool life at entry and exit\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO standards; catalog designation R390-18 06 08H-ML 2040\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with R390 and M-40 series milling cutter bodies.

Ensure the cutter body is fully removed from the spindle and the machine is locked out before seating or replacing inserts. Use the appropriate Torx or hex key to torque the clamping screw to the cutter body manufacturer's specified value. Inspect the insert pocket and screw thread for wear or debris before fitting a new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert 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\u003eInsert Shape\u003c\/strong\u003e: Parallelogram\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style \/ Series\u003c\/strong\u003e: R390\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 180608\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCrN, Al2O3, TiN (CVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 11.00 mm (0.4331 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 6.33 mm (0.2492 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 15.40 mm (0.6063 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.80 mm (0.0315 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.16 mm (0.1634 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 16.00 mm (0.6299 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive, 5 degrees\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 Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\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\u003eSided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI\/ISO Code\u003c\/strong\u003e: R390-18 06 08H-ML 2040\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 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: 5745690\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51728041673010,"sku":"5745690","price":609.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b59d443bd7393c5430d33357af2f4b8a_2dc81845-78a7-4d01-9312-cfa021c2d0af.jpg?v=1788686823","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5745690-milling-insert-grade-2040-r390","provider":"Voomi Supply","version":"1.0","type":"link"}
