It carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability at the cutting edge. The insert features a 55-degree diamond shape, a 3\/8 inch (9.53 mm) inscribed circle, a 1.19 mm (0.0469 inch) corner radius, and a PM chip breaker geometry. With 2 cutting edges per insert, it delivers efficient material removal on steel and cast iron workpieces. Licensed machinists and CNC operators install this insert as part of the CoroTurn 107 series tooling system.\u003c\/p\u003e\u003cp\u003eThis insert is part of the Sandvik Coromant CoroTurn 107 series, which is optimized for external turning of steel as the primary workpiece material (ISO material code P) and cast iron as a secondary workpiece material (ISO material code K). It is suited for both production and maintenance turning applications in industrial and job-shop environments. The neutral hand orientation makes it compatible with standard right-hand and left-hand CoroTurn 107 toolholders designed for DCMT-style inserts. The ISO designation for this insert is DCMT 11 T3 12-PM 4425, and the manufacturer catalog reference is DCMT 3(2.5)3-PM 4425.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for extended tool life on steel and cast iron\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape with 7-degree relief angle for positive clearance\u003c\/li\u003e\n\u003cli\u003e1.19 mm corner radius provides a balance between edge strength and surface finish\u003c\/li\u003e\n\u003cli\u003ePM chip breaker geometry engineered for reliable chip control in steel turning\u003c\/li\u003e\n\u003cli\u003e2 cutting edges per insert for cost-effective indexing\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation fits standard DCMT-style CoroTurn 107 toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Sandvik Coromant CoroTurn 107 series toolholders accepting DCMT-style inserts.

Use the appropriate Torx or hex key as specified by the toolholder manufacturer to seat the clamp or screw securely without overtightening. Verify seating of the insert in the pocket before resuming cuts. Machining professionals should follow applicable shop safety procedures and toolholder manufacturer guidelines for insert clamping.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DCMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (55-degree included angle)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4425\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\u003eChip Breaker\u003c\/strong\u003e: PM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inch \/ 9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1.19 mm (0.0469 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1563 inch (3.97 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inch (4.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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 Holding Method\u003c\/strong\u003e: Clamp, Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (ISO code P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron (ISO code K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DCMT 11 T3 12-PM 4425\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 11T3\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: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 7860820\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51755775983922,"sku":"7860820","price":276.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/955fc376a5a4427df423cdb94114c4f6_2a3e1041-9a5d-4122-ac57-64ea4f70e218.jpg?v=1788959556","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7860820-turning-insert-dcmt32-53-pm","provider":"Voomi Supply","version":"1.0","type":"link"}
