TNMG160404 NS9530 Tungaloy turning insert — uncoated cermet, 0.4 mm corner radius

The TNMG160404 NS9530 is an ISO-indexed triangular turning insert designed for finishing operations on steel, combining a sharp cutting edge with a double-sided chipbreaker for stable chip formation.

• ISO‑standard triangular insert
• Uncoated cermet for fine finishes
• 0.4 mm corner radius for precision
• Double-sided chipbreaker for stable chips

Achieve superior surface finish with low cutting forces

The uncoated cermet grade NS9530 is engineered for finishing applications on steel, offering a sharp cutting edge that reduces cutting forces and produces consistently smooth surfaces. Because the material combines ceramic and metallic phases, it maintains edge integrity at the low to moderate cutting speeds typical of fine turning, making the insert particularly effective during continuous cuts and small depths of cut. The smaller 0.4 mm corner radius balances strength and edge precision, helping to minimise vibration and deliver repeatable surface roughness values with fewer passes.

Secure fitting and ISO compatibility for predictable setup

Compatibility with toolholders is governed by ISO parameters such as form, relief angle, tolerance class, fastening method, size and thickness. The triangular ISO designation and 0° relief angle allow straightforward pairing with standard external holders and boring bars; the insert is supplied with a cylindrical hole for reliable clamping. System setup typically comprises the ISO insert, a matching external holder or boring bar, a support pad/clamp set and replacement screws. Specification-based matching reduces setup time and ensures repeatable clamping force, which supports consistent cutting performance across batches.

Stable chip control and process reliability

The insert’s double-sided chipbreaker promotes predictable chip formation during finishing cuts, improving evacuation and reducing the risk of built-up edge. For turning operations where surface quality and dimensional accuracy matter, this combination of geometry and chip control provides process stability and helps extend the number of productive indexings per edge. The 60° included angle of the triangular form offers a balance between accessibility and cutting-edge strength, making it suitable for external and internal turning tasks that prioritise finish.

How the grade helps in practical use and selection

Selecting NS9530 means choosing a finishing-grade that performs best under continuous, low- to medium-feed conditions on steel. As a cermet, it provides improved wear resistance and thermal stability compared with conventional grades for similar cutting regimes. For users less familiar with the material class: cermet inserts are particularly effective when a fine surface finish is required and when cutting forces must be kept low. When integrating this insert into a tooling system, verify holder geometry and tolerance class to ensure the plate seats correctly; correct seating maximises the benefit of the sharp edge and chipbreaker geometry.

FAQ

What holders are compatible with this TNMG insert?
Compatibility depends on ISO form, relief angle, tolerance class, fastening and size; the TNMG160404 NS9530 fits standard ISO TNMG holders with matching geometry.

Is this insert suitable for roughing operations?
The NS9530 grade is a finishing cermet optimised for low cutting forces and fine surface quality, so it is not designed for heavy roughing tasks.

Which materials can be machined with this grade?
This insert is intended primarily for steel finishing; it achieves best results on continuous cuts and small depths of cut in steel components.

How does the double-sided chipbreaker help in turning?
The double-sided chipbreaker on this triangular insert improves chip control during finishing, promoting stable evacuation and reducing the risk of built‑up edge.

How many usable edges does the insert provide?
Being double-sided and triangular, the insert offers multiple indexable cutting edges; effective life depends on cutting conditions and correct clamping.
