Identified by ISO code TNMG 22 04 04-PM 4415, this insert features a 60-degree triangular shape with a neutral hand orientation and a 0.4 mm corner radius. The carbide substrate carries a CVD-applied multilayer coating of Al2O3, TiN, and TiCN under manufacturer grade 4415, delivering wear resistance and thermal stability at the cutting edge. Six usable cutting edges per insert maximize tooling economy.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for medium to roughing turning passes on steel and cast iron workpieces in both residential shop and industrial production environments. The PM chip breaker geometry is optimized for continuous and interrupted cuts in steel (ISO P) with secondary suitability in cast iron (ISO K). Typical applications include shaft turning, facing, and profiling where consistent chip control and edge life are required. Installation is performed by qualified machinists or toolroom technicians as part of a standard insert changeout procedure.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTriangular 60-degree insert shape with 6 usable cutting edges for extended tooling economy\u003c\/li\u003e\n  \u003cli\u003eCVD multilayer coating: Al2O3, TiN, and TiCN for high wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003ePM chip breaker geometry engineered for reliable chip control in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation for flexible use in right-hand and left-hand toolholders\u003c\/li\u003e\n  \u003cli\u003e0.4 mm corner radius balances surface finish quality with edge strength\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and screw insert-holding methods\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement insert for SANDVIK COROMANT T-Max P series toolholders accepting TNMG-style inserts with a 0.5-inch inscribed circle.

Use the appropriate torx or hex key as specified by the toolholder manufacturer when tightening the clamping screw; do not exceed the toolholder manufacturer's recommended torque. Inspect the insert seat and shim for wear or debris before seating the new insert. Confirm edge index direction matches the intended cutting hand before resuming operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: TNMG 22 04 04-PM 4415\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees)\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: 4415\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: Al2O3, TiN, TiCN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.4 mm (0.0156 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (0.500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\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: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees (Clearance Code N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\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: 5.08 inches (L) x 2.13 inches (W) x 0.54 inches (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.54 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: 7860575\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51750714212658,"sku":"7860575","price":308.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/204843ac804f13c04178ce9e794403eb_7a89fe7b-398c-4864-b3df-dbb19ce1a9c1.jpg?v=1788918903","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7860575-turning-insert-tnmg431-pm-4415","provider":"Voomi Supply","version":"1.0","type":"link"}
