TNMG160404 NS520 Tungaloy turning insert — ISO triangular insert, finishing/light turning

The TNMG160404 NS520 Tungaloy insert is an ISO‑format triangular indexable insert designed for finishing to light turning of steel, offering stable cut behaviour and consistent surface quality in production environments

• ISO‑standard triangular insert
• Cermet grade NS520 for finishing
• 0.4 mm corner radius for accuracy
• Double‑sided chipbreaker design

Consistent surface quality and wear behaviour for finishing

The TNMG‑type triangular insert delivers reliable surface finish and repeatable size control thanks to the cermet grade NS520. The composition and coating of this grade favour low, even wear and reduced built‑up edge in finishing operations, which leads to fewer unplanned tool changes and steadier part quality. For operations where dimensional stability and a fine finish are priorities, the combination of a small 0.4 mm corner radius and refined edge preparation supports predictable results across series production.

Secure clamping and geometry that supports process reliability

Compatibility with the chosen clamping system is governed by form, clearance angle, tolerance class, fastening and plate dimensions; the insert features a cylindrical hole for positive, repeatable seating. The 60° geometry of the triangular shape gives three usable cutting edges per index and contributes to productivity in medium‑to‑light turning. The double‑sided chipbreaker enhances chip control during finishing passes, reducing interruptions and helping to maintain a stable cutting process even when feed rates vary slightly.

Application scope and handling guidance for efficient machining

Intended primarily for finishing to light turning of steel, this insert performs best with moderate cutting parameters that emphasise surface integrity and tool life. The NS520 grade supports fine tolerance work and uniform flank wear; operators are advised to select a holder and clamping set that match the plate thickness and size to exploit the insert’s performance. Where cycle stability and consistent part appearance matter, pairing the insert with a rigid holder and optimised coolant strategy will help achieve predictable, high‑quality production runs.

FAQ

What materials is this insert suitable for?
The TNMG160404 NS520 Tungaloy insert is formulated as a cermet grade primarily for finishing to light turning of steel, offering improved surface finish and uniform wear.

How many cutting edges are available per insert?
Thanks to the triangular 60° geometry, the insert provides three usable cutting edges; the double‑sided design supports economical indexing.

What is the corner radius and why does it matter?
The insert has a 0.4 mm corner radius, which balances edge strength with the ability to produce fine surface finishes and maintain dimensional accuracy during finishing passes.

Does the insert require a specific clamping style?
The insert uses a cylindrical hole and must be paired with a suitable holder and clamping set; compatibility depends on form, clearance, tolerance class, fastening, size and thickness as per ISO standards.
