Seco 03062792 DNMG432-M3 TK1501 Turning Insert Carbide

Product Description

The SECO 03062792 is a solid carbide turning insert in the DNMG-M3 series, designed for precision metal removal on CNC and manual turning centers. It carries a CVD-applied Duratomic multilayer coating — TiCN, Al2O3, and Cr — that delivers high wear resistance across a broad range of cutting conditions. The insert features a 55-degree diamond (rhombic) shape, a neutral hand orientation, a 0.0315-inch corner radius, and four usable cutting edges. With the M3 chip breaker geometry, it handles both finishing and medium machining passes. Machinists and CNC programmers specify this insert for demanding applications where tool life and surface finish consistency are critical.

This insert is suited for turning, facing, boring, and back-turning operations on steel, stainless steel, and cast iron workpieces. The Duratomic coating classification positions it for high wear-resistance to moderate wear-resistance and toughness applications in P, M, and K material categories. The M3 chip breaker geometry broadens its usefulness across finishing and medium-stock-removal passes. It is compatible with toolholders that accept DNMG-style inserts using clamp, pin, or lever lock holding methods. This insert is sold individually but carries a minimum order quantity of 10 pieces.

Key Features

• CVD Duratomic multilayer coating: TiCN, Al2O3, and Cr for extended tool life on steel, stainless steel, and cast iron
• 55-degree diamond (D-shape) insert with negative rake and negative side clearance for robust edge support
• M3 chip breaker geometry rated for finishing and medium machining operations
• Four cutting edges per insert maximizing cost-per-edge value
• 0.0315-inch corner radius and chamfered, honed cutting edge style for controlled surface finish
• Compatible with clamp, pin, and lever lock toolholder styles; multi-use for turning, facing, boring, and back turning

Compatibility

Designed for use in DNMG-style toolholders accepting clamp, pin, or lever lock insert holding methods. ANSI insert code DNMG432; ISO insert code DNMG150408-M3. Suitable for primary workpiece materials coded P, M, and K: steel, stainless steel, and cast iron.

Installation Notes

Installation is performed by machining personnel or CNC toolroom technicians following standard insert-indexing procedures. Power down and lock out the machine spindle before seating or indexing the insert. Use the appropriate torque wrench or clamp screw driver specified by the toolholder manufacturer — do not overtighten the clamping screw, as this can fracture the carbide. Inspect the insert pocket and seating surface for chips or debris before seating a new edge.
