Manufactured from solid carbide with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, this insert delivers wear resistance and thermal protection across a broad range of cutting conditions. The neutral hand orientation and 0.0469 inch (1.19 mm) corner radius make it suitable for general-purpose profiling and facing. It carries manufacturer grade 4425, optimized primarily for steel and cast iron machining. Each insert provides 8 usable cutting edges, reducing per-edge tooling cost. Licensed machinists and CNC programmers select this insert for production turning where consistent tool life and surface finish are required.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in medium to heavy turning applications on steel and cast iron workpieces in both residential shop and industrial production environments. The PM chip breaker geometry is engineered for positive chip control during continuous and interrupted cuts. The ISO code SNMG 15 06 12-PM 4425 and catalog designation SNMG 543-PM 4425 allow direct cross-reference to compatible SANDVIK COROMANT toolholders designed for SNMG insert pockets. Installation is performed by machinists and tooling technicians on turning centers configured for 5\/8 inch inscribed circle inserts.\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 heat management\u003c\/li\u003e\n  \u003cli\u003e8 cutting edges per insert for extended tool life value\u003c\/li\u003e\n  \u003cli\u003ePM chip breaker geometry for controlled chip formation in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation for flexible toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eSquare insert shape (SNMG) with 0 degree relief angle and tolerance code M\u003c\/li\u003e\n  \u003cli\u003eClamp and screw holding method for secure seating in compatible toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with SANDVIK COROMANT T-Max P series toolholders designed for SNMG inserts with a 5\/8 inch inscribed circle.

Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torx or hex key specified by the toolholder manufacturer when tightening the clamp or screw to avoid cracking the insert. Inspect the insert pocket for chips or debris before seating a new insert to ensure proper support and accurate edge positioning.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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\u003eSeries\u003c\/strong\u003e: T-Max P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiN (CVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 5\/8 inch (0.6250 inch \/ 15.88 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0469 inch (1.19 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/4 inch (0.2500 inch \/ 6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2500 inch (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHolding 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\u003eISO Code\u003c\/strong\u003e: SNMG 15 06 12-PM 4425\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.13 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 5.08 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.53 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\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: 7860720\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51744809779506,"sku":"7860720","price":401.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ac08c078189278acf1f613cf6bc825c0_42ceb0e4-3b26-4282-b4b5-fe2c39f58364.jpg?v=1788860756","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7860720-turning-insert-snmg543-pm-4425","provider":"Voomi Supply","version":"1.0","type":"link"}
