Manufactured to ANSI and ISO standard R390-18 06 12M-MM 2030, this right-hand, single-sided insert features a parallelogram shape with a positive 5-degree rake angle and a corner-rounded cutting edge style. The PVD-applied TiAlN and TiN dual coating delivers wear resistance and thermal stability during demanding milling operations. With an inscribed circle of 11.00 mm, a thickness of 6.33 mm, and a corner radius of 1.20 mm, this insert is sized for the R390-18 toolholder platform. It is sold individually with a minimum order quantity of 10 pieces.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for milling steel, stainless steel, superalloys, and titanium across a range of industrial and precision machining applications. The MM chip breaker geometry supports consistent chip control in both roughing and finishing passes. Maximum depth of cut reaches 16.00 mm, making this insert suitable for shoulder milling and face milling operations on machining centers and mills where tight tolerances and surface finish are required. It is installed by machinists and CNC operators in job shops, production facilities, and aerospace or energy sector environments where difficult-to-machine materials are common.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD-applied TiAlN and TiN dual coating for wear resistance in high-temperature cutting\u003c\/li\u003e\n  \u003cli\u003ePositive 5-degree rake angle with corner-rounded cutting edge reduces cutting forces and edge chipping\u003c\/li\u003e\n  \u003cli\u003eMM chip breaker geometry promotes reliable chip evacuation across material grades P30, M25, and S20\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 16.00 mm suits both roughing and semi-finishing shoulder milling passes\u003c\/li\u003e\n  \u003cli\u003eScrew-lock insert holding method ensures secure seating and repeatable edge positioning\u003c\/li\u003e\n  \u003cli\u003eCompliant with ANSI and ISO standards; catalog code R390-18 06 12M-MM 2030 for direct cross-reference\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with M-40 and R390 series milling cutter bodies.

Ensure the machine spindle is fully stopped and locked out before seating or replacing inserts. Use the correct torx or hex key to drive the clamping screw to the toolholder manufacturer's specified seating procedure without over-torquing. Inspect the pocket seating surface for chips or contamination before installing a new insert to ensure proper edge height and runout.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 2030\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R390\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI \/ ISO Code\u003c\/strong\u003e: R390-18 06 12M-MM 2030\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Parallelogram\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: R390\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 180612\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: TiAlN and TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P30; M25; S20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel; Stainless Steel; Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MM\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\u003eSingle or Double Sided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 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\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1.20 mm (0.0472 inches)\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\u003eWidth\u003c\/strong\u003e: 11.00 mm (0.4331 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\u003eHole Diameter\u003c\/strong\u003e: 0.16 mm (0.1634 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.29 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI; ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 per package; minimum order quantity 10\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: 5745943\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51748708385074,"sku":"5745943","price":508.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b59d443bd7393c5430d33357af2f4b8a_64596531-e1dc-4909-bba7-93e02e03b237.jpg?v=1788897059","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5745943-r390-milling-insert-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
