TNGG160402 NS520 – ISO turning insert, triangular 16 mm, Tungaloy

TNGG160402 NS520 is an ISO‑standard indexable insert developed for finishing to light turning of steel, offering high surface quality and consistent wear behaviour

• Cermet grade NS520 for finishing
• ISO-standard triangular 16 mm size
• 0.2 mm corner radius for precise edges
• Double-sided chipbreaker for economy

High-precision finishing and consistent surface quality

The NS520 grade is a cermet or coated cermet formulation optimised for finishing and light machining of steel, delivering improved surface quality and dimensional stability compared with conventional grades. The cutting edge geometry and substrate chemistry reduce built-up edge and promote even flank wear, which helps to maintain component tolerances over extended runs. This makes the insert particularly suited to applications where consistent cosmetic finish and repeatable form are decisive.

ISO compatibility and secure clamping in common tool systems

As an ISO‑standard insert, the plate’s compatibility is governed by its form, relief angle, tolerance class, fastening, size and thickness. The triangular 16 mm format with a 4.76 mm thickness and a 0° relief angle fits a wide range of external holders and boring bars designed for ISO turn‑insert systems. Typical system components comprise the insert itself, a matching external holder or boring bar, a shim/clamp set and replacement fixing screws, enabling secure clamping and repeatable seating for machining processes that demand low micro‑vibration and steady cutting conditions.

Efficient chip control and economical finishing cycles

The double-sided chipbreaker design supports predictable chip formation during finishing passes, aiding coolant access and reducing edge loading. With a 0.2 mm corner radius the insert balances rigidity and edge strength to allow fine finishing without sacrificing edge life. Together these features contribute to lower rework rates and improved process efficiency — an advantage in production environments where throughput and surface integrity both matter. The carbide substrate ensures the mechanical stability required for steady, repeatable cutting.

FAQ

Which machining tasks are best for this insert?
The TNGG160402 NS520 insert is designed for finishing to light turning of steel where high surface quality and dimensional consistency are required.

Can this grade be used for roughing operations?
NS520 is a cermet grade optimised for finishing and light machining; for heavy roughing a more robust grade should be selected.

How is compatibility with the toolholder ensured?
Compatibility depends on form, relief angle, tolerance class, fastening, size and thickness; the ISO format and the insert’s dimensions make it compatible with standard ISO external holders and boring bars when the holder is specified accordingly.

How many usable edges does the insert provide?
The triangular plate offers multiple indexable edges; the double‑sided chipbreaker further enhances economical edge usage and predictable wear.

Is this insert supplied with a coating?
The NS520 designation indicates a cermet or coated cermet formulation; the TNGG160402 NS520 plate uses a cermet substrate optimised for finishing steel.
