TNMG 160408 NS520 Drehen — TNMG turning insert, cermet, 0.8 mm radius — Tungaloy

The TNMG160408 NS520 is a triangular, ISO‑standard turning insert designed for fine to light finishing of steel, prioritising surface quality and dimensional stability.

• ISO‑standard triangular insert for turning
• Cermet grade NS520 for fine finishing
• 0.8 mm corner radius for consistent edges
• Double‑sided geometry with cylindrical hole

High-precision finishing with measurable results

The insert delivers a clear focus on surface finish and repeatable part accuracy, making it suitable where tight tolerances matter. Its NS520 cutting grade is a coated cermet composition optimised for finishing passes on steel; this results in a stable wear pattern and predictable regrinding intervals. When used in a correctly specified holder, the insert’s geometry and 60° triangle form ensure reproducible engagement conditions, which supports efficient process planning and shorter cycle time variability.

Longer effective tool life through optimised materials

The combination of a cermet cutting edge and a carbide substrate brings the advantage of improved wear behaviour during light cuts. The grade emphasises uniform abrasion resistance, which reduces the risk of catastrophic flank wear and allows extended usage between indexings. As a result, batch processes benefit from fewer tool changes and more stable surface‑quality trends, contributing to lower machine downtime and improved overall equipment effectiveness.

Smooth integration into existing turning systems

Compatibility is determined by insert form, clearance angle, tolerance class, fixing method, size and thickness; this insert matches ISO holder standards and fits common external holders or boring bars. The 0° clearance angle and 4.76 mm thickness enable a secure clamp, while the cylindrical hole provides stable assembly and repeatable seating. This predictable mechanical interface simplifies inventory management and reduces set‑up time when swapping inserts between machines.

Application focus and practical advantages

Designed primarily for external and internal turning, the insert performs best in finishing to light machining of steel where surface appearance and dimension are priorities. The double‑sided chipbreaker supports controlled chip formation under finishing conditions, lowering the likelihood of surface damage from poor chip evacuation. Selecting the NS520 sort is particularly advantageous when consistent finish and low burr formation are required across medium‑run production.

FAQ

What types of machining is this insert designed for?
The TNMG160408 NS520 insert is specified for external and internal turning with a focus on finishing and light machining of steel.

How does the NS520 grade affect tool life and finish?
The NS520 cermet grade promotes uniform wear and high surface quality, extending effective tool life in finishing operations compared with uncoated grades.

Is the insert compatible with standard ISO holders?
Compatibility depends on form, clearance, tolerance and fastening, but the TNMG160408 follows ISO dimensions and fits commonly used external holders and boring bars that accept TNMG inserts.

What is the significance of the 0.8 mm corner radius?
A 0.8 mm corner radius balances edge strength and finish quality, reducing vulnerability to chipping while maintaining a fine surface texture on the workpiece.

Can this insert be indexed for multiple edges?
Yes, the double‑sided triangular geometry provides multiple usable cutting edges, increasing the number of indexings before replacement.
