VNMG 160412 NS9530 — Turning insert (uncoated cermet, 35°) by Tungaloy

The VNMG160412 NS9530 is an ISO‑standard indexable turning insert designed for fine finishing of steel components in continuous‑cut applications.

• ISO‑standard rhombic 16 mm insert
• Uncoated cermet NS9530 for fine finishing
• Cylindrical hole and double‑sided chipbreaker
• Low cutting forces and high surface quality

Achieve finer surfaces with lower cutting forces

The uncoated cermet grade NS9530 provides a sharp cutting edge and reduced adhesion tendencies, resulting in low cutting forces and an improved finish on steel. As a finishing grade it is tailored for small depths of cut and continuous feeds, where the combination of edge stability and chip control produces consistent surface integrity. The fine microstructure of the cermet helps to maintain edge geometry over longer cycles, reducing the need for frequent index changes and supporting predictable machining throughput.

Consistent fit and simple integration into ISO systems

Supplied as an ISO‑standard insert, compatibility with toolholders is determined by form, relief angle, tolerance class, fastening method, size and thickness. The rhombic VNMG160412 form and the cylindrical hole make it suitable for a broad range of external holders and boring bars; the specified 0° relief angle and the 35° lead orientation ensure correct seating and cutting geometry. When selecting a holder, match the insert geometry and thickness to maintain clamping accuracy and minimise vibration for best surface results.

Stable chip formation and repeatable productivity

A double‑sided chipbreaker and the robust cermet substrate support predictable chip evacuation and stable chip formation during finishing cuts. This reduces the risk of built‑up edge and improves process stability, particularly in continuous cut scenarios. The insert’s sharp edge and material behaviour favour low cutting forces, which in turn helps to extend tool life and maintain part tolerances across long production runs.

Practical recommendations for finishing steel

For finishing operations on steel, use modest feed rates and shallow depths of cut to exploit the NS9530 grade’s strengths: superior surface quality and edge stability. The insert is intended for finishing rather than heavy roughing; pair the insert with a suitably rigid holder and ensure proper clamping torque on the mounting screw. The system build typically comprises the ISO insert, a matching external holder or boring bar, a shim/clamping set and replacement screws to guarantee repeatable clamping accuracy.

FAQ

How does the NS9530 grade differ from conventional carbide grades?
The NS9530 uncoated cermet grade focuses on a very sharp edge and low cutting forces, which delivers improved surface finish and longer edge life in finishing cuts compared with some conventional carbide grades.

Is the VNMG160412 suitable for external and internal turning?
Yes, the VNMG160412 insert is designed for both external and internal turning applications when paired with an appropriate holder or boring bar that matches its geometry and clamping method.

How many usable cutting edges does this insert provide?
The insert is double‑sided; depending on orientation and indexing practice, multiple edges can be used before replacement, offering cost‑effective utilisation of the plate.

What cutting conditions are recommended for finishing steel with this insert?
Use shallow depths of cut and moderate feed rates for continuous cuts to exploit the grade’s low cutting forces and to achieve the best surface quality and dimensional control.

Can this insert be used for interrupted cuts or roughing operations?
The VNMG160412 NS9530 is optimised for finishing and continuous cuts; interrupted heavy roughing is not ideal for this grade and may reduce edge life or performance.
