Seco 03096372 DNMG432-M6 TP3501 Carbide Turning Insert

Product Description

The SECO 03096372 is a DNMG432-M6 carbide turning insert designed for precision metal-cutting operations on CNC lathes and turning centers. It carries the TP3501 manufacturer grade and features a CVD-applied Duratomic multilayer coating consisting of TiCN, Al2O3, and Cr, delivering thermal resistance and wear protection during continuous and interrupted cuts. The insert measures 1.2204 inches in length with a 0.5000-inch inscribed circle, a 0.1874-inch thickness, and a 0.0315-inch corner radius. With four available cutting edges, a negative rake geometry, and a honed cutting-edge style, it is suited for productive, cost-effective turning in steel and stainless steel applications.

This insert is primarily applied in steel machining (ISO material group P, grades P20, P30, P40) with secondary capability in stainless steel (ISO material group M). Supported operations include turning, facing, boring, and back turning, making it versatile across roughing and semi-finishing passes. The M6 chip breaker geometry manages chip flow effectively over a wide range of depths of cut, with a maximum depth of cut of 0.5787 inches. It is installed by licensed machinists and CNC operators in production turning environments where consistent tool life and surface finish are priorities.

Key Features

• Duratomic CVD multilayer coating (TiCN, Al2O3, Cr) for extended wear resistance in steel turning
• Four cutting edges per insert for reduced cost per edge
• M6 chip breaker optimized for turning, facing, boring, and back turning
• Negative rake, neutral hand geometry compatible with clamp, pin, and lever lock toolholders
• Honed cutting-edge style reduces microchipping on interrupted cuts
• Conforms to ANSI and ISO standards; ISO code DNMG150408-M6

Compatibility

Designed as an OEM-style replacement and standard-format insert for DNMG-M6 series toolholders that accept clamp, pin, or lever lock insert holding methods. Suitable for toolholders conforming to ANSI and ISO DNMG insert seating specifications.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Always bring the spindle to a full stop and engage machine lockout before indexing or replacing inserts. Verify that the insert seat and clamping components are clean and free of chips before seating the insert. Follow the toolholder manufacturer torque and clamping specifications for the specific clamp, pin, or lever lock system in use.
