Identified by ISO code DNMG 11 04 04-PM 4425, this insert features a 55-degree diamond shape with a neutral hand orientation and a 0.40 mm (0.0156 inch) corner radius. The substrate is solid carbide with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN — a coating stack engineered to resist crater wear and flank wear in continuous and interrupted cuts. It is installed by machinists and CNC turning specialists in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is intended primarily for turning steel (ISO P workpiece material) and secondarily for cast iron (ISO K). The PM chip breaker geometry is suited to light-to-medium roughing and finishing passes where chip control and surface finish consistency are critical. With four available cutting edges per insert, it offers a cost-effective edge count for high-volume turning applications. It fits clamp and screw holding methods on compatible toolholders sized for DNMG inserts with a 3\/8-inch inscribed circle.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e55-degree diamond insert shape (Shape Code D) for versatile turning approaches\u003c\/li\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, TiN — high wear and heat resistance\u003c\/li\u003e\n\u003cli\u003eManufacturer grade 4425 optimized for steel and cast iron workpiece materials\u003c\/li\u003e\n\u003cli\u003ePM chip breaker for reliable chip control in light-to-medium cutting passes\u003c\/li\u003e\n\u003cli\u003eFour cutting edges per insert for extended tooling value\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with both left- and right-hand toolholder setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement turning insert for DNMG-style toolholders accepting a 3\/8-inch inscribed circle insert with clamp or screw holding.

Always power down and lock out the machine before indexing or replacing inserts. Use the correct torque driver and seating procedure specified by the toolholder manufacturer to ensure proper insert clamping and prevent micro-movement during cutting. Inspect the insert pocket and clamp for wear or debris before seating a new edge.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DNMG 11 04 04-PM 4425\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DNMG\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 Hand\u003c\/strong\u003e: Neutral\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\u003eCorner Radius\u003c\/strong\u003e: 0.40 mm (0.0156 inch)\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\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inch \/ 4.76 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.150 inch (3.81 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle (Clearance Code N)\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\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 P)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron (ISO K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.54 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3.74 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.43 inches\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: 7860704\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51737807913266,"sku":"7860704","price":305.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d835e570594324a5742c7ece6712fd3d_c8de8455-e1ba-4833-b105-5dff0d2fe91f.jpg?v=1788793802","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7860704-dnmg331-pm-4425-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
