Sumitomo 6NCWNGA432WG-BNC2125 – Turning Carbide Insert

The Sumitomo 6NCWNGA432WG-BNC2125 turning carbide insert excels in interrupted cutting operations on steel and hardened steel workpieces, thanks to its tin coating which provides a strong balance between wear resistance and toughness. This insert is well-suited for applications where a strong, sharp cutting edge is needed to handle the shock loads and vibration inherent in interrupted cuts. With its trigon 80-degree shape and 0.5000″ inscribed circle, the BNC2125 insert is a reliable choice for CNC operators working with demanding steel and hardened steel machining tasks.
