TNMG160404 NS520 Tungaloy — Indexable Turning Insert, Cermet, 0.4 R

A TNMG160404 indexable turning insert designed for finishing to light machining of steel, offering high surface quality and dimensional stability

• ISO‑norm TNMG 160404 form
• NS520 cermet for fine surface finish
• 0.4 mm corner radius for precision
• Double‑sided with cylindrical centre hole

Consistent finishing for improved part quality

The NS520 grade is a cermet developed for finishing to light machining of steel, delivering a balance between hardness and toughness that promotes a stable cutting edge and even wear. Thanks to the combination of the grade and a cemented carbide substrate, the insert sustains a controlled wear pattern which supports repeatable dimensional accuracy and a superior surface finish on turned parts. This behaviour reduces rework and supports predictable cycle times in serial production.

Fast set‑up and reliable compatibility in ISO systems

The insert follows the ISO TNMG geometry, easing interchange in standard holders; compatibility is determined by form, 0° relief angle, tolerance class, fastening, size and thickness. The triangular 60° cutting angle provides a familiar cutting geometry for general turning operations while the double‑sided design doubles the available cutting edges before replacement. The cylindrical hole allows stable clamping and simple indexation, so changeovers are straightforward and tool inventory remains lean.

Productivity through predictable tool life and chip control

With a 0.4 mm corner radius and a chipbreaker designed for light finishing, the grade supports reliable chip control and consistent cutting forces, which helps maintain spindle and workpiece stability. The insert’s specification is oriented to steady wear progression rather than aggressive metal removal, making it particularly suitable when surface quality and tolerance are priorities in the machining process. The result is improved uptime and lower overall cost per part in applications where finishing performance matters.

FAQ

What materials is this insert suited for?
The TNMG160404 NS520 insert is optimised for steel finishing and light machining; the NS520 cermet grade focuses on surface quality and uniform wear when machining steel.

Is the insert compatible with standard ISO TNMG holders?
Compatibility is determined by geometry, relief angle, tolerance class, fastening, size and thickness; the TNMG160404 follows the ISO form and fits holders designed for TNMG 160404 inserts.

How does the double‑sided design affect service life?
A double‑sided configuration provides two usable edges per side, extending the number of indexings and improving overall life before replacement of the insert.

What advantages does the NS520 grade deliver in finishing operations?
NS520 offers a fine balance of hardness and toughness for finishing, promoting a consistent cutting edge, improved surface finish and predictable dimensional control in finishing passes.
