Sumitomo 3NUTPGA331 BN7000 – Turning Carbide Insert

The Sumitomo 3NUTPGA331 BN7000 turning carbide insert excels in finish machining operations on steel and hardened steel workpieces, thanks to its tin-coated PCBN substrate which provides a strong balance of wear resistance and toughness. This insert is well-suited for applications where a sharp, precise edge is required, and its 0.0156″ corner radius and 60-degree triangle shape help to minimize cutting forces and prevent edge breakdown. With a compact design featuring a 0.3750″ inscribed circle, the 3NUTPGA331 is ideal for turning operations that demand both accuracy and surface finish quality.

Buying Considerations

Single-pack option — useful for prototype runs or qualification before bulk commitment. Mid-tier pricing reflects Sumitomo’s production-grade tolerances rather than economy substrate.

Tip: Match this insert to a holder whose seat matches the ISO designation. If you’re unsure, send us the holder model and we’ll confirm compatibility before shipping.
