VNMG 120408 NS9530 — Turning insert VNMG120408E-TSF by Tungaloy

The VNMG120408E-TSF NS9530 is an ISO‑standard turning insert crafted for fine finishing of steel, offering a sharp cutting edge and optimised chip control for continuous cuts.

Fine finishing cermet grade NS9530
Sharp cutting edge for low cutting forces
ISO VNMG120408 format, rhombic 35°
Corner radius 0.8 mm for superior surface quality

Consistent fine finishing for steel components

The uncoated cermet grade NS9530 is formulated for finishing cuts on steel, where a sharp cutting edge and low cutting forces translate directly into improved part quality. As an ISO‑compatibility insert in the VNMG family, the indexable design maintains repeatable positioning and predictable wear. For continuous cutting and small depth‑of‑cut operations, this grade reduces the need for extensive secondary finishing, thus shortening overall process time and supporting higher first‑pass yields.

Predictable tool set‑up and chip control

Designed in the VNMG120408 format with a TSF chipbreaker, the insert matches common holders by form, free angle and thickness, making integration straightforward. The rhombic plate with a 35° cutting angle and a corner radius 0.8 mm ensures dimensional stability and a consistent contact geometry. The cylindrical hole and 4.76 mm plate thickness provide secure clamping; selecting the correct holder and clamp set secures repeatable cutting performance and reduces vibration, which benefits surface finish and tool life.

Productivity gains and process reliability

Lower cutting forces achieved by this finishing grade lead to reduced spindle load and less elastic deflection of the workpiece and toolholder, which improves tolerance adherence in series production. The NS9530 grade is particularly effective when small, continuous material removals are required, offering a balance of surface quality and economical consumption. These attributes contribute to a predictable machining routine and support leaner downstream operations, yielding measurable gains in throughput and component quality.

Practical application and handling notes

Suitable for both external and internal turning, the insert is optimised for finishing passes and small cross‑sections. For best results, pair the insert with a holder matched to VNMG120408 geometry and use feed and speed settings aligned with fine finishing recommendations for steel; the TSF chipbreaker aids smooth chip evacuation in stable cutting scenarios. If there is uncertainty about holder compatibility or cutting data, Metav Werkzeuge can supply guidance on holder selection, clamping sets and replacement screws to ensure a complete system setup.

FAQ

Is this insert suitable for finishing steel?
Yes. The VNMG120408E-TSF NS9530 is a finishing grade cermet specifically developed for steel finishing, offering a sharp cutting edge and low cutting forces for improved surface quality.

Which holders are compatible with this VNMG format?
Compatibility depends on form, free angle, tolerance class, fastening method, size and thickness; the VNMG120408 geometry matches standard VNMG holders when those parameters are aligned.

What does the TSF chipbreaker do?
The TSF chipbreaker is designed for controlled chip formation during continuous cuts and small depths of cut, which helps maintain stable cutting conditions with the NS9530 grade.

How does the corner radius affect the surface finish?
A corner radius of 0.8 mm balances edge strength and finish quality: it supports a smoother surface while retaining adequate edge stability for finishing passes.

Which SKU should be ordered for this insert?
Order using the dealer SKU 6750976-Tungaloy or the manufacturer article number 6750976 for the VNMG120408E-TSF NS9530 insert.
