Seco 02787010 Turning Insert DNMG431-FF2 TP1030 Cermet

Product Description

The SECO 02787010 is a DNMG431-FF2 series cermet turning insert with a TP1030 manufacturer grade and multilayer PVD TiAlSiN coating. It features a 55-degree diamond insert shape with a neutral hand orientation and a negative rake geometry. The inscribed circle measures 0.5 inches, the corner radius is 0.0157 inches, and the insert thickness is 0.1874 inches. The FF2 chip breaker geometry is designed for controlled chip formation during finish and semi-finish turning operations. Four cutting edges are available per insert, making it a cost-effective option for high-volume machining environments. This insert is suited for machinists and CNC operators working with steel and stainless steel workpieces.

This insert is intended for use in turning applications on CNC lathes and manual turning centers. It is rated primarily for steel (ISO material code P) and secondarily for stainless steel (ISO material code M), corresponding to material grades P10 and P15. Applicable operations include turning, facing, boring, and back turning. The FF2 chip breaker designation indicates suitability for finishing to light roughing passes on these materials. The insert is held by clamp, pin, or lever lock toolholders compatible with the DNMG insert style.

Compatibility

Designed for use in DNMG-style toolholders that accept clamp, pin, or lever lock holding methods. Compatible with turning, facing, boring, and back turning operations on steel and stainless steel workpieces. Industry standard number DNMG431-FF2; ISO equivalent DNMG150404-FF2.

Installation Notes

Installation is performed by a machinist or CNC tooling technician. Power down and de-energize the machine before changing inserts. Seat the insert fully in the pocket and confirm the holding mechanism — clamp, pin, or lever lock — is properly engaged before resuming operation. Follow the toolholder manufacturer guidelines for torque and seating procedures; do not force an insert that does not seat cleanly, as this can damage the pocket or the cutting edge.
