It carries the ISO designation CNMG 12 04 12-PF 4425 and belongs to the T-Max P series. The insert is manufactured from solid carbide substrate with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, targeting wear resistance and thermal stability during continuous and interrupted steel and cast iron cutting. The 80-degree diamond shape provides a strong nose geometry, and the PF chip breaker is optimized for finishing and light roughing passes. With a 1\/2 inch (0.5000 inch) inscribed circle and a 1.19 mm (0.0469 inch) corner radius, this insert fits standard CNMG toolholders and delivers consistent edge performance across multiple cutting edges.\u003c\/p\u003e\u003cp\u003eThis insert is suited for production turning in residential shop, job shop, and industrial manufacturing environments. The grade 4425 is formulated for steel as the primary workpiece material (ISO material code P) and cast iron as the secondary workpiece material (ISO material code K). The PF chip breaker geometry handles finishing cuts where close tolerances and surface finish consistency are priorities. It is used by machinists and CNC operators on lathes requiring a neutral-hand, screw-and-clamp held insert in CNMG pocket toolholders. This insert is sold individually; minimum order quantity is 10 units per purchase.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating — TiCN, Al2O3, TiN — for wear resistance on steel and cast iron\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (Shape Code C) provides strong cutting geometry for turning operations\u003c\/li\u003e\n\u003cli\u003ePF chip breaker geometry optimized for finishing and light roughing applications\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with standard CNMG clamp and screw toolholder pockets\u003c\/li\u003e\n\u003cli\u003e4 cutting edges per insert for extended tool life and lower cost per edge\u003c\/li\u003e\n\u003cli\u003eTolerance Code M and Clearance Code N meet standard CNMG dimensional specifications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style indexable replacement for CNMG 12 04 12 pocket toolholders that accept clamp and screw insert holding. The ISO insert code CNMG 12 04 12-PF 4425 can be cross-referenced using the manufacturer catalog number CNMG 433-PF 4425 when sourcing equivalent toolholder fits.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC toolroom technicians. Power down and zero out the machine before indexing or replacing inserts. Use the appropriate torx or hex key as specified by the toolholder manufacturer to achieve proper seating torque on the clamp screw — do not over-torque or under-torque the clamping mechanism. Inspect the toolholder pocket for chips, debris, or wear before seating a new insert edge.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG 12 04 12-PF 4425\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degrees)\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: PF\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 (CVD Process)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (0.5000 inch \/ 12.70 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: 3\/16 inch (0.1875 inch \/ 4.76 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2030 inch (5.16 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\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\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\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\u003eSeries\u003c\/strong\u003e: T-Max P\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\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 7860792\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51749345689906,"sku":"7860792","price":256.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ea98c3751e8fce5f3b86e0fc4420a04b_983b0162-bce1-4fc7-b994-8e785fda9cc4.jpg?v=1788904772","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7860792-turning-insert-cnmg433-pf-4425","provider":"Voomi Supply","version":"1.0","type":"link"}
