Manufactured to grade S40T and coated via CVD with a TiCN, Al2O3, and TiN multilayer stack, this insert delivers wear resistance and thermal stability in demanding cutting environments. The insert carries an inscribed circle of 6.80 mm, a thickness of 3.59 mm, and a 0.80 mm corner radius. It features a positive rake angle of 20 degrees and an ML chip breaker geometry optimized for light to medium cutting depths. ANSI and ISO codes are both R390-11 T3 08E-ML S40T. Installation is by screw-holding method.\u003c\/p\u003e\u003cp\u003eThis insert is suited for shoulder milling applications in ISO material groups M (stainless steel) and S (superalloys and titanium). The R390 series platform is widely used in both roughing and semi-finishing passes where controlled chip evacuation and edge security are required. The ML chip breaker geometry is particularly effective at moderate feed rates when workpiece surface finish and tool life consistency are priorities. This is a single-sided, right-hand insert with two cutting edges per insert, which is standard for indexable screw-lock toolholders in the R390 and M-32 cutter series families.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for thermal resistance and flank wear control\u003c\/li\u003e\n\u003cli\u003ePositive rake angle of 20 degrees reduces cutting forces on difficult-to-machine alloys\u003c\/li\u003e\n\u003cli\u003eML chip breaker geometry engineered for stainless steel, superalloys, and titanium\u003c\/li\u003e\n\u003cli\u003e0.80 mm corner radius (1\/32 inch) balances edge strength and surface finish\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut: 10.00 mm (0.3937 inches)\u003c\/li\u003e\n\u003cli\u003eTwo cutting edges per insert; single-sided, right-hand orientation\u003c\/li\u003e\n\u003cli\u003eScrew-lock holding method for secure seating in indexable toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with R390 and M-32 cutter series toolholders.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct Torx or hex key for the clamping screw as specified by the toolholder manufacturer, and do not over-tighten or substitute fasteners. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert to ensure proper contact and runout.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: S40T\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\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiN (CVD)\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\u003eCorner Radius\u003c\/strong\u003e: 0.80 mm (0.0315 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\u003eMaximum Depth of Cut\u003c\/strong\u003e: 10.00 mm (0.3937 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 20 degrees positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting 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\u003eChip Breaker\u003c\/strong\u003e: ML\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHolding 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: Stainless Steel, Superalloys, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M40, S35\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\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\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: 5853479\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51752073855282,"sku":"5853479","price":506.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2ab91d54c657f8d2460e90f55358be6e_b5991b05-b2f6-4009-96f5-43832106cecc.jpg?v=1788925660","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5853479-milling-insert-s40t-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
