Manufactured in the VNMG331-M3 series, this insert features a 35-degree diamond (rhombic) shape with a negative rake and zero-degree relief angle, making it suited for finishing and medium machining operations. The TK1501 grade uses a CVD-applied Duratomic multilayer coating of TiCN, Al2O3, and Cr, which delivers high wear resistance across steel, stainless steel, and cast iron workpieces. With four usable cutting edges and a neutral hand orientation, this insert provides consistent performance and cost efficiency per edge for production turning environments. It is installed and managed by machinists, CNC operators, and toolroom technicians.\u003c\/p\u003e\n\u003cp\u003eThis insert is applied in back turning, facing, profiling, and general turning operations. The M3 chip breaker geometry is optimized for finishing to medium material removal rates, handling steel (P), stainless steel (M), and cast iron (K) workpiece materials with high to moderate wear resistance and toughness. The 1\/64-inch corner radius and chamfered, honed cutting edge style support surface finish quality and edge stability at typical production feeds and speeds for ISO P, M, and K material groups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e35-degree diamond (V) insert shape with negative rake and negative side clearance for rigid tool holding\u003c\/li\u003e\n  \u003cli\u003eCVD Duratomic multilayer coating: TiCN, Al2O3, and Cr for extended tool life on steel, stainless steel, and cast iron\u003c\/li\u003e\n  \u003cli\u003eM3 chip breaker geometry supports finishing and medium machining operations\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert for maximum value and reduced tooling cost per edge\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation for flexible toolholder compatibility\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp, pin, and lever-lock insert holding methods\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and production insert for VNMG-style turning toolholders accepting a 3\/8-inch inscribed circle insert with a 0.1500-inch hole diameter.

Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and manufacturer-specified clamping hardware for the lever-lock, pin, or clamp toolholder in use. Inspect the toolholder pocket and seating surface for chips or wear before seating the new insert to ensure proper edge height and runout.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: VNMG331\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: VNMG160404\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: VNMG-M3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TK1501\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\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\u003eInsert Shape\u003c\/strong\u003e: V - Diamond (Rhombic) 35 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: M3 (Finishing and Medium Machining)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0157 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 1.3070 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/16 inch (0.1874 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.6142 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Chamfered and 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: Cast Iron (K), Steel (P), Stainless Steel (M)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: K10, K20, K30\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: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 03062816\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51564066111794,"sku":"03062816","price":56.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a3af3982ee0944b2619e6ebfe0a03354_ccb6b283-27ea-4573-b75a-5728bf8bd8f3.jpg?v=1786510009","url":"https:\/\/voomisupply.com\/products\/seco-03062816-turning-insert-vnmg331-m3-tk1501-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
