It carries the ANSI insert code DCMT32.52 and ISO code DCMT11T308, featuring a 55-degree diamond (rhombic) shape with a 7-degree relief angle and a 0.79 mm (0.0313 inch) corner radius. The CVD-applied multilayer coating stack — TiCN, Al2O3, and TiN — delivers high wear resistance with moderate toughness, making it well suited for steel roughing and medium machining passes. This insert is part of the CoroTurn 107 series and is intended for installation by machinists and CNC tooling technicians.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered primarily for steel workpiece materials (ISO material group P), targeting applications that demand high wear resistance transitioning to moderate wear resistance and toughness. Typical use cases include roughing and medium machining passes on low-alloy and carbon steels in production turning environments. The UR chip breaker geometry is optimized to control chip flow across varying depths of cut and feed rates common in those operations. The insert fits holders using either clamp or screw mounting methods, consistent with standard CoroTurn 107 tooling setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for wear resistance and thermal stability\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape (DCMT) with positive side clearance for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eUR chip breaker geometry suited for roughing and medium machining operations\u003c\/li\u003e\n  \u003cli\u003e9.53 mm (0.375 inch) inscribed circle with 0.79 mm corner radius\u003c\/li\u003e\n  \u003cli\u003eInsert thickness of 3.97 mm (0.1563 inch); tolerance code M, clearance code C\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and screw insert holding methods\u003c\/li\u003e\n  \u003cli\u003eManufacturer grade 4425 — optimized for ISO P steel cutting applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement turning insert for SANDVIK COROMANT CoroTurn 107 series toolholders accepting DCMT32.52 (ANSI) or DCMT11T308 (ISO) inserts with clamp or screw holding.

Always power down and lock out the machine spindle before changing inserts. Seat the insert fully and evenly in the pocket before tightening the clamp or screw to the toolholder manufacturer's specified method; never force or tap an insert into position. Inspect the insert pocket and shim for wear or debris before seating a new insert to ensure proper support and accurate tool geometry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DCMT32.52\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DCMT11T308\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: D - Diamond (Rhombic) 55 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 9.53 mm (0.375 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.79 mm (0.0313 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3.97 mm (0.1563 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: UR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Roughing and Medium Machining\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4425\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\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (ISO P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp and Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\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\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 7860880\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51737618055474,"sku":"7860880","price":264.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2f1fb3a7c11d8215c9fd01bcf00e7bb8_390cef76-0d8f-41f3-90d0-59cd6d9ab453.jpg?v=1788791466","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7860880-turning-insert-dcmt32-52-ur-4425","provider":"Voomi Supply","version":"1.0","type":"link"}
