Cargo Carbide TNMG FW CO25S Carbide Turning Inserts are designed for CNC turning applications in steel where reliable cutting performance is required under challenging machining conditions. The TNMG-FW geometry is available in multiple sizes and is suitable for compatible negative turning tool holders.

The CO25S carbide grade is part of the Cargo Carbide steel-grade range and is recommended for suitable TNMG-FW applications. Cargo Carbide's published grade chart lists CO25S for TNMG-FW in 160404, 160408 and 160412 sizes.

TNMG-FW inserts feature a triangular negative configuration and are commonly used for CNC turning operations where a stable cutting edge and multiple usable cutting edges are beneficial. The FW chipbreaker/geometry is associated with finishing-oriented applications in comparable TNMG-FW tooling.

Cargo Carbide TNMG FW CO25S is suitable for manufacturers looking for a carbide turning insert for steel machining, including general CNC turning, semi-finishing, finishing and appropriate difficult or interrupted machining conditions.

The available nose-radius options allow the user to select the appropriate insert according to workpiece geometry, cutting depth, feed, machine rigidity and required surface finish.
