TPGH 090204 NS9530 Tungaloy — ISO turning indexable insert with W10 chipbreaker and 11° clearance

A TPGH 090204 NS9530 Tungaloy ISO-standard triangular insert designed for precision finishing in turning applications on steel.

• Uncoated cermet grade NS9530 for fine finishing
• Sharp cutting edge with low cutting forces
• ISO-standard triangular 09 size, 11° clearance
• 0.4 mm corner radius and W10 chipbreaker

Precision finishing performance for turning operations

The insert is engineered as a finishing grade to produce superior surface quality in continuous cutting on steel. Its uncoated cermet composition delivers a sharp, wear-resistant cutting edge that maintains profile integrity during extended runs, while the combination of low cutting forces and a tuned chipbreaker reduces vibration and heat generation. These properties result in consistent dimensional accuracy and reduced rework, making the insert a pragmatic choice where surface finish and repeatability are priorities. The technical specification supports stable machining at small depths of cut and modest feed rates typical for finishing passes.

Reliable compatibility and geometrical clarity

Supplied in an ISO-standard triangular format (09 size) with an included angle of 60°, the insert fits a wide range of external holders and boring bars when the holder’s form, clearance angle (11°), tolerance class, mounting arrangement, size and thickness are matched. The insert thickness of 2.38 mm, the 0.4 mm corner radius and the presence of a cylindrical hole with one-sided countersink (70°–90°) are decisive for seating and clamping stability. These well-defined geometric parameters simplify selector checks and reduce the time needed to confirm holder compatibility, enabling a faster set-up and more predictable process control.

Process advantages and application guidance

The NS9530 grade and W10 chipbreaker are tailored for continuous finishing cuts on steel, offering a balance between edge sharpness and wear resistance. The insert’s design reduces cutting forces, which helps to protect both the tool and the workpiece from chatter and thermal distortion. For best results, choose a matching holder and feed strategy consistent with finishing practice: shallow depths of cut, stable fixture, and reduced feed to exploit the cermet’s edge quality. Where interrupted cuts or heavy build-up occur, select a different chipbreaker or a more robust grade to maintain process security.

Integration into the tooling system and practical notes

As part of a standard ISO insert system, each component functions in concert: the indexable insert, a matched external holder or boring bar, and the appropriate clamping set and replacement screws form the complete tooling solution. The insert’s sharp cutting geometry and uncoated surface favour applications where surface appearance and tight tolerances are required. When ordering or specifying, reference the model series and article codes to ensure the correct variant is supplied; for complex applications, Metav Werkzeuge’s technical advisors can provide parameter recommendations and help with holder selection to optimise cycle time and component quality. The Tungaloy finishing insert is particularly effective where consistent surface integrity matters.

FAQ

Is this insert suitable for finishing operations on steel?
Yes. The NS9530 uncoated cermet grade of the TPGH 090204 NS9530 Tungaloy insert is designed as a finishing grade for steel, offering a sharp edge and low cutting forces for high surface quality.

Which holder characteristics determine compatibility with the insert?
Compatibility is determined by the holder’s form, clearance angle, tolerance class, mounting, size and thickness; the insert’s 11° clearance and 2.38 mm thickness are key reference values.

What does the W10 chipbreaker mean for chip control?
The W10 chipbreaker is tuned to provide controlled chip formation during continuous finishing cuts, reducing the risk of long, stringy chips and supporting stable machining performance.

Can the insert be used for internal and external turning?
Yes. The ISO triangular format and the insert’s geometry allow use in both external holders and appropriate boring bars for internal turning, provided the holder matches the insert’s dimensions and clamping style.

How should the 0.4 mm corner radius influence feed selection?
A 0.4 mm corner radius is small and suited to finishing feeds; selecting a moderate feed rate helps achieve the desired surface finish while avoiding excessive edge loading.
