TNMG inserts are the most widely used general-purpose negative-rake carbide turning inserts for standard CNC lathe operations. They are mainly designed for outer diameter turning, face turning and light chamfering on common industrial workpieces.

Featuring a stable 60-degree triangular geometry and multiple usable cutting edges, TNMG inserts handle both medium roughing and precision finishing tasks. They work reliably on carbon steel, alloy steel, stainless steel and regular cast iron, covering most routine mass-production turning jobs in mechanical parts, automotive components and hydraulic fittings.

Suitable for both continuous cutting and slight interrupted cuts, these versatile turning inserts deliver balanced wear resistance and stable surface quality on general CNC machining applications.
