Designed for external and internal turning operations, this insert features a 55-degree diamond (rhombic) shape, a neutral hand orientation, a 5\/8-inch inscribed circle, and a 3\/64-inch corner radius. Grade TP3501 targets moderate wear resistance combined with toughness, making it suitable for steel and stainless steel at P20, P30, and P40 material grades. Licensed machinists and CNC turning specialists are the primary installers of this insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered for roughing and medium machining operations on steel and stainless steel workpieces. Its M6 chip breaker geometry supports back turning, boring, facing, and general turning applications across a maximum depth of cut of 0.7008 inches. The four available cutting edges and negative rake geometry allow multiple indexed positions per insert, reducing per-edge tooling cost in production turning environments. It is suited to both light production and heavy-duty roughing passes on CNC lathes and turning centers using clamp, pin, or lever-lock holding methods.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDuratomic CVD coating (TiCN, Al2O3, Cr) for moderate wear resistance and toughness in steel and stainless applications\u003c\/li\u003e\n  \u003cli\u003eM6 chip breaker geometry optimized for roughing and medium machining\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert for extended tooling life and reduced cost per edge\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape with negative rake and negative side clearance for secure seating\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp, pin, and lever-lock holding systems\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style reduces microchipping at the insert tip\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in DNMG-series turning toolholders that accept a 5\/8-inch inscribed circle insert with clamp, pin, or lever-lock retention.

Always power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and manufacturer-specified clamp or lever-lock hardware for the toolholder to ensure proper seating of the insert. Inspect the insert pocket and seating surface for chips or debris before installing a new edge; a contaminated pocket can cause premature insert failure or dimensional deviation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DNMG543\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DNMG190612\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\u003eInscribed Circle\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 3\/64 inch (0.0472 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 1.5276 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.7008 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2500 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\u003eManufacturer Grade\u003c\/strong\u003e: TP3501\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, Cr (Duratomic CVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: M6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Roughing, Medium Machining\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\u003eCutting Edge Style\u003c\/strong\u003e: Honed\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\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P) - P20, P30, P40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel (M)\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: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Back Turning, Boring, Facing, Turning\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: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.33 inches L x 1.97 inches W x 0.47 inches H\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: 03100387\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51561815867698,"sku":"03100387","price":479.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c94cd731f445d0f93f6ad06e3a92b05_a37fbc60-7784-47e7-9c75-da07480e2ae3.jpg?v=1786469130","url":"https:\/\/voomisupply.com\/products\/seco-03100387-turning-insert-dnmg543-m6-tp3501-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
