It carries the grade designation 4425 and features a CVD-applied multilayer coating of Al2O3, TiCN, and TiN for wear resistance and thermal stability. The insert has a 55-degree diamond shape (shape code D), a 3\/8-inch inscribed circle, and a 0.20 mm corner radius, making it well suited for finishing and semi-finishing passes. It is part of the CoroTurn 107 series and is held in place by a clamp or screw depending on the toolholder. Machinists and CNC operators install this insert in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is intended primarily for machining steel (ISO material code P) and secondarily for cast iron (ISO material code K). The neutral hand orientation makes it compatible with standard right-hand toolholders used in the CoroTurn 107 system. It is a single-piece insert with 2 cutting edges, a clearance code of C, and a tolerance code of M. Typical applications include longitudinal turning, facing, and profiling on low-alloy and carbon steels as well as grey cast iron components in medium-volume production runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: Al2O3, TiCN, and TiN for extended tool life on steel and cast iron\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape with 2 usable cutting edges per insert\u003c\/li\u003e\n\u003cli\u003e0.20 mm (0.0079 inch) corner radius for controlled surface finish on finishing passes\u003c\/li\u003e\n\u003cli\u003eManufacturer grade 4425 optimized for ISO P (steel) and ISO K (cast iron) workpiece materials\u003c\/li\u003e\n\u003cli\u003ePF chip breaker geometry for reliable chip control in light to medium cuts\u003c\/li\u003e\n\u003cli\u003ePart of the CoroTurn 107 series, compatible with clamp and screw holding methods\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CoroTurn 107 series toolholders that accept DCMT-style inserts with a 3\/8-inch inscribed circle.

The machine spindle must be stopped and the turret or toolholder fully secured before seating or indexing the insert. Use the appropriate torx or hex key to the toolholder manufacturer's specified procedure when tightening the clamp or screw. Inspect the insert pocket and seating surface for chips or debris before installing a new edge to ensure proper seating and repeatability.\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 degrees)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CoroTurn 107\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: Al2O3, TiCN, 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: PF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.20 mm (0.0079 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inch (0.1563 inch)\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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\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 Standard Number\u003c\/strong\u003e: DCMT 11 T3 02-PF 4425\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.44 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: 7861037\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51747715514674,"sku":"7861037","price":291.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c5d3c0cc177a56c61eca96f2c5a6af22_c6031d33-c56e-42b2-9423-2c7945a3a23d.jpg?v=1788884576","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7861037-turning-insert-dcmt-32-50-pf-4425","provider":"Voomi Supply","version":"1.0","type":"link"}
