It carries a multilayer TiCN, Al2O3, and TiN CVD-style coating that delivers high wear resistance while maintaining adequate toughness against the demanding cutting conditions of austenitic and similar stainless grades. The insert measures 15.5 mm in length with a 0.5-inch inscribed circle and a 1\/32-inch corner radius. It features a 55-degree diamond (rhombic) geometry, a negative side clearance, and a neutral hand orientation, making it suitable for a range of straight turning toolholders. CNC machinists and toolroom technicians working on turning centers and lathes typically select this grade.\u003c\/p\u003e\u003cp\u003eThis insert is intended for finishing passes on stainless steel components in both production and job-shop environments. Its MF chip breaker geometry is optimized to control chips at light-to-moderate depths of cut, making it well suited for achieving tight surface finishes on tubular or shaft-type parts common in food processing, chemical, medical, and general industrial applications. The maximum depth of cut is 14.70 mm, supporting a range of finishing stock-removal scenarios. The insert accommodates both clamp and pin holding methods, providing flexibility across compatible toolholder configurations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMultilayer TiCN, Al2O3, and TiN coating for high wear resistance on stainless steel\u003c\/li\u003e\n\u003cli\u003eMF chip breaker geometry engineered for finishing operations with controlled chip formation\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape (ANSI code DNMG442) with 4 usable cutting edges\u003c\/li\u003e\n\u003cli\u003eNegative side clearance and neutral hand orientation for broad toolholder compatibility\u003c\/li\u003e\n\u003cli\u003e1\/32-inch corner radius balances edge strength and surface finish quality\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 14.70 mm suitable for finishing pass applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in toolholders accepting DNMG442 (ISO DNMG 15 06 08) style inserts with clamp or pin holding methods.

Use the appropriate torque wrench and clamping hardware specified by the toolholder manufacturer — do not over-tighten the clamp screw, as this can crack the insert or distort the seat. Inspect the toolholder pocket and seat for chips or wear before seating a new insert. Always verify tool offset data in the CNC control after indexing or replacing an insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DNMG442\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DNMG 15 06 08-MF 2015\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: D - Diamond (Rhombic) 55 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 2015\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: MF (Finishing)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.6102 inches (15.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.25 inches (6.35 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches (0.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2032 inches (5.16 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.5787 inches (14.70 mm)\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 Holding Method\u003c\/strong\u003e: Clamp, Pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel (ISO Code M)\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: 5.08 inches L x 2.13 inches W x 0.53 inches H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 5731725\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51730913296690,"sku":"5731725","price":429.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c66652ec499836f0fbf73603904f452d_6d42b3c1-329a-429e-a736-f279b34d8b8c.jpg?v=1788724705","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5731725-turning-insert-dnmg442mf-2015","provider":"Voomi Supply","version":"1.0","type":"link"}
