TNGA 160404 NS520 Tungaloy turning insert — ISO triangular insert, 60° geometry

The TNGA160404 NS520 Tungaloy insert is an ISO-standard triangular indexable insert designed for turning, optimised for finishing and light machining of steel with a focus on surface quality and steady wear behaviour

• ISO-standard triangular insert, 60° geometry
• Cermet grade NS520 for fine finishing
• 0.4 mm corner radius for tight tolerances
• Compatible with external holders and boring bars

Predictable finishing with a cermet grade built for surface quality

The NS520 grade is a cermet or coated cermet formulation developed for finishing to light machining of steel, emphasising surface finish and dimensional accuracy. Compared with general-purpose carbide grades, a cermet cutting edge produces finer surface structure and promotes even wear, which reduces rework and inspection cycles. The triangular insert’s 60° included angle and 0° relief help maintain a stable cutting geometry during small-depth finishing passes. For shops prioritising reproducible part quality, this insert delivers repeatable results while lowering the frequency of insert changes.

System compatibility and straightforward integration on CNC lathes

Compatibility with a toolholder depends on several defined parameters: shape, relief angle, tolerance class, fastening method, size and thickness. The ISO designation and the triangular form make the insert compatible with a wide range of external holders and boring bars when the holder matches the 16 mm size and 4.76 mm thickness. The insert is supplied with a cylindrical centre hole, enabling secure clamping in standard pockets; a matching underlay or clamp set and replacement screws complete the system. Integrators benefit from clear interchangeability: select a holder and clamping kit that correspond to the ISO geometry to ensure safe and accurate seating.

Practical shop-floor advantages: precision, economy and handling

A 0.4 mm corner radius is effective for tight tolerances and fine finishes without compromising edge life, which supports longer uninterrupted production runs and lower tooling spend per part. The absence of an integral chipbreaker means chip control must be matched to the workpiece and cutting conditions — choosing the correct chip-control geometry and process parameters reduces cycle time and scrap. The insert’s carbide substrate provides the mechanical support needed for finishing passes while the NS520 surface characteristics help maintain a stable cutting edge. For small-batch and high-precision turning, this combination offers a balance of productivity and process security.

FAQ

What materials is the TNGA160404 NS520 best suited for?
The TNGA160404 NS520 insert is optimised for finishing and light machining of steel; the NS520 cermet grade emphasises surface quality and steady wear when turning steel components.

How is compatibility with toolholders determined?
Compatibility depends on form, relief angle, tolerance class, fastening, size and thickness; ensure the holder matches the 16 mm size, 4.76 mm thickness and ISO triangular geometry of the insert.

Does the insert include a chipbreaker?
This variant is supplied without an integrated chipbreaker (ohne); chip control should be achieved through holder geometry, cutting parameters or an alternative chip-control insert design.

Can the insert be used for heavy roughing operations?
The TNGA160404 NS520 is intended for finishing to light machining rather than heavy roughing; for heavy cuts a grade and geometry designed for higher forces and chip evacuation should be selected.

What advantages does the NS520 grade provide on the shop floor?
NS520’s cermet characteristics deliver improved surface finish and uniform wear, which supports consistent part accuracy and fewer insert changes during finishing cycles.
