TNGG 160404 NS520 Tungaloy – ISO turning insert for finishing applications, triangular 60° geometry

The TNGG160404 NS520 Tungaloy is an ISO‑standard triangular insert designed for external and internal turning, focused on finishing and light machining of steel where surface quality and dimensional accuracy are priorities.

• ISO triangular insert, 60° geometry
• Cermet grade NS520 for fine finishing
• Double-sided chipbreaker, cylindrical hole
• 0.4 mm corner radius, 4.76 mm plate thickness

Consistent finishing with a cermet grade optimised for surface quality

The cermet composition used in this grade combines high hardness and thermal stability to deliver a fine surface finish and limited crater wear during finishing passes. Designed as a cermet or coated cermet insert, the grade NS520 emphasises dimensional accuracy and uniform wear, which reduces the need for frequent rework and supports predictable part tolerances. For shops prioritising repeatable finishes on steels, the material choice and cutting edge geometry translate into measurable improvements in process stability.

Secure clamping and repeatable geometry for reliable process control

The triangular shape with a 60° included angle provides versatile seating in standard holders, while the cylindrical hole and one‑piece indexable design ensure stable clamping and straightforward indexing. With a 0° relief angle, a 0.4 mm corner radius and a plate thickness of 4.76 mm, the insert supports controlled engagement and consistent tool overhang limits. Compatibility with a given holder will depend on form, relief angle, tolerance class, clamping arrangement, size and thickness; attention to these parameters ensures repeatable set‑ups and consistent cycle‑time results.

Practical advantages in workshop operation and system integration

The double‑sided chipbreaker reduces tool cost per edge by offering two usable cutting faces and promotes predictable chip formation for light to finishing cuts. Typical use is in external and internal turning where high surface quality and steady wear behaviour are required. The complete system comprises the insert together with a matching external holder or boring bar, a seat/clamping set and replacement screws, permitting rapid reconditioning of assemblies. If uncertain whether this insert matches specific tooling or process parameters, Metav Werkzeuge provides technical guidance by email or telephone to align grade and chipbreaker selection with the component material and machining strategy.

FAQ

What materials is this insert suited for?
The TNGG160404 NS520 insert is specified for finishing and light machining of steel, with the NS520 cermet grade focusing on surface quality and dimensional stability.

How is the insert clamped and indexed?
Clamping relies on the cylindrical hole and the seat geometry of the chosen holder; the triangular 60° format and double‑sided chipbreaker permit safe indexing to the second cutting edge when required.

Which cutting tasks benefit most from this grade and geometry?
The combination of cermet NS520 and a fine corner radius is best for finishing passes where consistent surface finish and tight tolerances are important.

What should be checked for holder compatibility?
Ensure the holder matches the insert form, relief angle (0°), tolerance class, clamping method, size (16 mm) and thickness (4.76 mm) to guarantee correct seating and repeatable results.
