Seco 03094146 Turning Insert DNMP431-MF2 TP3501 Carbide

Product Description

The SECO 03094146 is a DNMP431-MF2 series solid carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. It carries a TP3501 grade designation with a CVD-applied Duratomic multilayer coating of TiCN, Al2O3, and Cr, engineered to extend tool life under demanding cutting conditions. The insert features a 55-degree diamond shape, a neutral hand orientation, a 0.5 inch inscribed circle, and a 1/64 inch corner radius. With four available cutting edges and an MF2 chip breaker geometry, it delivers consistent chip control during finish and semi-finish operations on steel and stainless steel workpieces.

This insert is suited for medium to heavy turning applications in production and job-shop environments. Its primary target material is steel, with secondary suitability for stainless steel, aligning with ISO material codes P and M. Rated material grades include P20, P30, and P40. The MF2 chip breaker geometry supports back turning, boring, facing, and standard longitudinal turning. It is typically installed by machinists and CNC operators on toolholders accepting DNMP-style inserts with clamp, pin, or lever lock holding methods.
