It carries the industry-standard code DNMG431-M3 (ISO: DNMG150404-M3) and features a CVD-applied Duratomic multilayer coating of TiCN, Al2O3, and Cr for high wear resistance. The 55-degree diamond (D-shape) geometry with a negative rake and neutral hand provides four usable cutting edges per insert. An inscribed circle of 0.5 inches and a corner radius of 0.0157 inches (1\/64 inch) make it well suited for finishing and medium machining passes. Machinists and CNC operators working in job shops and production environments will find this insert in high-volume steel and cast iron applications.\u003c\/p\u003e\n\u003cp\u003eThis insert targets external and internal turning operations including facing, boring, back turning, and standard OD turning. Its grade characteristics are optimized for steel (P), stainless steel (M), and cast iron (K) workpiece materials, ranging from high wear resistance to moderate toughness across those material groups. The M3 chip breaker geometry supports both finishing and medium machining operations, making it adaptable across varying depth-of-cut requirements in a single setup. Compatible holding methods include clamp, pin, and lever lock toolholders designed for DNMG-style inserts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD Duratomic multilayer coating (TiCN, Al2O3, Cr) for extended tool life in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape with negative rake and neutral hand for versatile toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eFour usable cutting edges per insert, reducing per-edge tooling cost\u003c\/li\u003e\n  \u003cli\u003eM3 chip breaker supports finishing and medium machining operations\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.5945 inches accommodates a wide range of turning passes\u003c\/li\u003e\n  \u003cli\u003eComplies with both ANSI and ISO insert standards (DNMG431 and DNMG150404)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in DNMG-style toolholders that accept clamp, pin, or lever lock holding methods.

Inspect the insert pocket and shim for wear or debris before seating a new insert, as a contaminated pocket will cause premature edge failure. Use the toolholder manufacturer's recommended clamping torque procedure for DNMG lever lock, pin, or clamp-style holders. Verify insert orientation and hand designation against the toolholder spec sheet before engaging the first cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DNMG431\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DNMG150404-M3\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: TK1501\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, Cr (CVD Duratomic)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: M3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: K10, K20, K30\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0157 inches (1\/64 inch, 0.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 1.2204 inches (15.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1874 inches (3\/16 inch, 4.76 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.5000 inches (15.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2028 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.5945 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\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\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered, Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Pin, Lever Lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Back Turning, Boring, Facing, Turning\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Finishing, Medium Machining\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron (K), Steel (P), Stainless Steel (M)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package (MOQ: 10)\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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 03062791\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563473404210,"sku":"03062791","price":319.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1e2833b56ec9460f90e4e0610cc3894b_5c00ed14-fd40-43a0-9968-4ac80cd4680b.jpg?v=1786498196","url":"https:\/\/voomisupply.com\/products\/seco-03062791-turning-insert-dnmg431-m3-tk1501-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
