This square-shaped carbide insert carries ISO designation SNMG 12 04 04-PM 4425 and features a multilayer CVD coating of TiCN, Al2O3, and TiN over a grade 4425 carbide substrate. The PM chip breaker geometry is engineered for finishing and medium turning on steel and cast iron. With 8 cutting edges per insert and a neutral hand configuration, this insert delivers efficient edge utilization in production turning environments. Licensed machinists and CNC operators working in job shops, production floors, and maintenance machining departments are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning steel and cast iron workpieces in both roughing and medium-duty applications. The grade 4425 substrate and CVD multilayer coating provide wear resistance and thermal stability during continuous and interrupted cuts on P-group steels and K-group cast irons. The PM chip breaker controls chip formation across a range of feed rates, making this insert appropriate for general-purpose turning on component diameters where consistent surface finish and predictable tool life are required. It seats in standard SNMG 432 or compatible toolholders using clamp or screw holding methods.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMultilayer CVD coating: TiCN, Al2O3, TiN for thermal and wear resistance\u003c\/li\u003e\n  \u003cli\u003eGrade 4425 carbide substrate optimized for steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e8 cutting edges per insert for maximum edge utilization\u003c\/li\u003e\n  \u003cli\u003ePM chip breaker geometry for controlled chip formation in medium turning\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation for use in standard right-hand and left-hand holders\u003c\/li\u003e\n  \u003cli\u003eSquare insert shape with 0 degrees relief angle; clamp and screw compatible mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with toolholders designed for SNMG-style inserts using clamp or screw holding methods.

Power down and lock out the machine before changing inserts. Inspect the insert pocket and clamping hardware for debris or wear before seating a new insert. Follow the toolholder manufacturer torque specifications for clamping screws; do not overtighten, as this can fracture the carbide. Index to a fresh cutting edge rather than flipping worn edges back into the cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: SNMG 12 04 04-PM 4425\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square\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: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiN (CVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PM\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: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (0.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (4.76 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2030 inches (5.16 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\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\u003eClearance Code\u003c\/strong\u003e: N\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\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: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 7860716\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51731022283058,"sku":"7860716","price":36.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ac08c078189278acf1f613cf6bc825c0_d265ccc9-d14a-430c-8031-4bfa675997fe.jpg?v=1788725974","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7860716-turning-insert-snmg431-pm-4425","provider":"Voomi Supply","version":"1.0","type":"link"}
