This indexable carbide insert features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability during continuous and interrupted cuts. The insert has a 55-degree diamond shape, a 0.5000-inch inscribed circle, a 3\/16-inch thickness, and a 0.40 mm corner radius. It carries a neutral hand designation and is part of the T-Max P series. Machinists and CNC operators install this insert in compatible toolholders for production turning of steel and cast iron components.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning steel (ISO material group P) and cast iron (ISO material group K) in both roughing and finishing applications. The PM chip breaker geometry controls chip formation across a range of depths of cut and feed rates, making it appropriate for medium-duty turning on both manual and CNC turning machines. It is sold individually with a minimum order quantity of 10 units and is intended for professional machine shop use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape (Shape Code D) with 4 cutting edges\u003c\/li\u003e\n  \u003cli\u003ePM chip breaker geometry for controlled chip evacuation in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e0.40 mm corner radius for medium-finish turning applications\u003c\/li\u003e\n  \u003cli\u003eClamp and screw insert holding method for secure seating in toolholder\u003c\/li\u003e\n  \u003cli\u003eISO Code DNMG 15 04 04-PM 4415 for cross-reference and toolholder matching\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eThis insert is compatible with DNMG-style toolholders accepting a 0.5000-inch inscribed circle, 3\/16-inch thick diamond insert with clamp or screw holding. Primary workpiece materials are steel (ISO P) and cast iron (ISO K). ISO code DNMG 15 04 04-PM 4415 should be used to verify toolholder fitment.

Before indexing or replacing the insert, the machine must be powered off and the spindle fully stopped. Seat the insert firmly in the toolholder pocket and tighten the clamp or screw to the toolholder manufacturer's specified torque. Inspect the insert seat and clamp for wear or contamination before each insert change to ensure proper clamping and accurate tool geometry.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (55-degree included angle)\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\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1875 inch \/ 4.76 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.40 mm (0.0156 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\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: PM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4415\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\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\u003eHole Diameter\u003c\/strong\u003e: 0.2030 inch (5.16 mm)\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 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\u003eSeries\u003c\/strong\u003e: T-Max P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DNMG 15 04 04-PM 4415\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.08 inches length x 2.13 inches width x 0.53 inches height\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\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: 7859234\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51748284137778,"sku":"7859234","price":348.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d835e570594324a5742c7ece6712fd3d_2ae5cf64-0f89-4f47-af3a-21a886eaeedb.jpg?v=1788891735","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7859234-turning-insert-dnmg431-pm-4415","provider":"Voomi Supply","version":"1.0","type":"link"}
