Product Description
The SECO 03096606 is a solid carbide turning insert in the VNMG series, designed for precision metal cutting in CNC and manual turning applications. It carries the industry standard designation VNMG331-MF3 and ISO code VNMG160404-MF3, with a manufacturer grade of TP3501 and a Duratomic CVD coating of TiCN, Al2O3, and Cr. The 35-degree diamond insert shape with a chamfered and honed cutting edge delivers controlled chip formation across a wide range of material grades. The MF3 chip breaker geometry supports medium finishing cuts. With 4 usable cutting edges and a neutral hand orientation, this insert offers consistent performance and efficient edge utilization in production turning environments.
This insert is rated for primary use on steel (ISO material code P, grades P20, P30, P40) and secondary use on stainless steel (ISO material code M). Typical applications include back turning, facing, profiling, and general turning operations. The VNMG form factor suits standard toolholders using clamp, pin, or lever lock holding methods. It is a practical choice for machinists running medium to high production volumes on steel and stainless components where surface finish and dimensional accuracy are critical.

Compatibility
Designed for use in VNMG-style toolholders accepting a 3/8-inch inscribed circle insert. Compatible holding methods include clamp, pin, and lever lock systems. Intended for steel (P20, P30, P40) and stainless steel workpiece materials. Multi-use capable for back turning, facing, profiling, and turning operations.
Installation Notes
Installation is performed by machinists or toolroom technicians following standard insert indexing procedures for VNMG toolholders. Ensure the machine is powered down and the spindle is fully stopped before indexing or replacing inserts. Seat the insert firmly against the toolholder pocket and verify the clamping mechanism is fully engaged before resuming cuts. Follow the toolholder manufacturer’s torque guidance for screw-lock or lever-lock systems.
