Identified by ISO code SNMG 12 04 08-PM 4425, this insert features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN for high wear resistance and thermal stability at the cutting edge. The PM chip breaker geometry promotes reliable chip control across a broad range of feed rates and depths of cut. With a neutral hand orientation and 8 usable cutting edges, this insert is suited for production turning in machine shops, job shops, and heavy manufacturing environments.\u003c\/p\u003e\u003cp\u003eThis insert is engineered primarily for turning steel and cast iron workpieces in both roughing and semi-finishing applications. The 0.79 mm corner radius and 12.70 mm inscribed circle make it appropriate for medium to heavy material removal passes. It is installed by machinists and CNC operators using clamp or screw holding methods in compatible SNMG-style toolholders. The PM chip breaker designation targets consistent chip evacuation during interrupted or continuous cuts on ferrous materials, including low-alloy steels, carbon steels, and gray or ductile cast iron.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for extended tool life on ferrous materials\u003c\/li\u003e\n\u003cli\u003ePM chip breaker geometry for reliable chip control across variable feed and depth conditions\u003c\/li\u003e\n\u003cli\u003e8 cutting edges per insert for cost-effective edge utilization\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with a wide range of SNMG toolholders\u003c\/li\u003e\n\u003cli\u003eSquare insert shape (S) with N clearance and M tolerance for consistent fit and dimensional accuracy\u003c\/li\u003e\n\u003cli\u003eClamp and screw holding method for secure seating under heavy cutting loads\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in SNMG-style turning toolholders that accept a 1\/2 inch inscribed circle, 3\/16 inch thick square insert.

Power down and lock out the machine spindle before seating or indexing the insert. Ensure the insert pocket and seating surface are clean and free of chips before clamping. Follow the toolholder manufacturer's specified clamping torque and seating procedure to avoid insert micro-fracture or poor seating.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: SNMG 12 04 08-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\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\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.500 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.79 mm (0.0313 inches)\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: 0.203 inches (5.16 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 8\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: N\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\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: T-Max P\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\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: 7860717\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51728827023666,"sku":"7860717","price":276.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ac08c078189278acf1f613cf6bc825c0.jpg?v=1788696464","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7860717-turning-insert-snmg432-pm-4425","provider":"Voomi Supply","version":"1.0","type":"link"}
