Carrying a CVD-applied tri-layer coating of TiCN, Al2O3, and TiN, this insert delivers wear resistance and thermal stability across demanding cutting conditions. The parallelogram insert shape with a positive 20-degree rake angle reduces cutting forces and promotes clean chip evacuation. With an inscribed circle of 6.80 mm, a thickness of 3.59 mm, and a corner radius of 0.80 mm, this insert is sized to the R390-11T308 insert size code. It is held in place by a screw and is rated for a maximum depth of cut of 10.00 mm. Installation and application are handled by machinists and CNC tooling technicians.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for milling steel, cast iron, and hard materials, corresponding to ISO material groups P, K, and H. Typical applications include shoulder milling and face milling operations on machining centers where consistent tool life and dimensional accuracy are required. The PM chip breaker geometry supports stable cutting in both roughing and semi-finishing passes on steel and cast iron workpieces. The insert is compatible with the M-32 and R390 cutter series. Right-hand cutting orientation is standard for this part.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD tri-layer coating: TiCN, Al2O3, and TiN for wear resistance and thermal protection\u003c\/li\u003e\n  \u003cli\u003ePositive 20-degree rake angle reduces cutting forces on steel and cast iron\u003c\/li\u003e\n  \u003cli\u003ePM chip breaker geometry supports roughing and semi-finishing applications\u003c\/li\u003e\n  \u003cli\u003eCorner-rounded cutting edge style with 0.80 mm corner radius\u003c\/li\u003e\n  \u003cli\u003eSingle-sided insert with 2 cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eScrew-clamp holding method for secure, repeatable positioning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with the R390 and M-32 cutter series.

Power down and lock out the machine spindle before changing inserts. Use the appropriate Torx or hex key specified by the toolholder manufacturer when tightening the clamping screw  -  do not overtighten. Inspect the insert pocket seat and clamping screw condition before seating a new insert to ensure proper contact 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: 4220\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 Size Code\u003c\/strong\u003e: 11T308\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI \/ ISO Code\u003c\/strong\u003e: R390-11 T3 08M-PM 4220\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: TiCN, Al2O3, TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: 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\u003eRake Angle\u003c\/strong\u003e: 20 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Corner Rounded\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\u003eInscribed Circle\u003c\/strong\u003e: 6.80 mm (0.2677 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3.59 mm (0.1413 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 10.00 mm (0.3937 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 6.80 mm (0.2677 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.11 mm (0.1102 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\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P20, H25\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\u003eHolding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\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\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: 5745675\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51741837328690,"sku":"5745675","price":367.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/38ecf10af004d4d2005ddc0bc549caf7_6c6c63f2-a799-4f52-b56a-83dcd2bff38c.jpg?v=1788833747","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5745675-milling-insert-4220-r390","provider":"Voomi Supply","version":"1.0","type":"link"}
