Carrying the ANSI and ISO designation R390-11 T3 10M-KH 3330, this insert features a parallelogram shape with a positive rake angle of 9 degrees and a 90-degree included angle. The cutting edge geometry is corner-rounded with a 1.00 mm corner radius, and the insert measures 11.00 mm wide and 3.97 mm thick. A CVD-applied multilayer coating of TiCN, Al2O3, and TiN in manufacturer grade 3330 provides wear resistance and thermal stability suited to interrupted and continuous cutting operations in cast iron.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for milling cast iron workpieces in production machining environments. It fits R390 and M-32 cutter bodies and is held in place by a screw. With a maximum depth of cut of 10.00 mm (0.3937 inches), the KH chip breaker geometry is optimized for cast iron applications where controlled chip evacuation and edge security are priorities. The right-hand cutting orientation and single-sided design make setup straightforward for machinists running standard R390 tooling on CNC milling equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with CVD multilayer TiCN, Al2O3, and TiN coating for extended tool life in cast iron\u003c\/li\u003e\n  \u003cli\u003eKH chip breaker geometry designed specifically for cast iron primary workpiece material\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle (9 degrees) reduces cutting forces and heat generation at the edge\u003c\/li\u003e\n  \u003cli\u003eCorner-rounded cutting edge with 1.00 mm corner radius for smooth surface finish and edge stability\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 10.00 mm suits a wide range of shoulder milling pass depths\u003c\/li\u003e\n  \u003cli\u003eCompatible with R390 and M-32 cutter series for broad toolholder interchangeability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with M-32 and R390 series milling cutter bodies.

Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate Torx or hex key as specified by the cutter body manufacturer to secure the clamping screw — do not overtighten or use impact tools on insert screws. Inspect the pocket seat and clamping screw for damage before installing a fresh insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: R390-11 T3 10M-KH 3330\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: R390-11 T3 10M-KH 3330\u003c\/li\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\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 3330\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiN (CVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 11.00 mm (0.2677 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3.97 mm (0.1413 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1.00 mm (0.0394 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 10.00 mm (0.3937 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.2677 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1102 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 21 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 9 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 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\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: KH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: M-32, R390\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.74 inches L x 1.54 inches W x 0.43 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 6428045\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51728491970866,"sku":"6428045","price":308.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9be111ff8ff2e8b41f4cc39f12226e2.jpg?v=1788692086","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-6428045-milling-insert-r390-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
