TPGT090204 NS9530 Tungaloy turning insert — triangular finishing insert for precision turning

The TPGT090204 NS9530 Tungaloy turning insert is an ISO‑format, triangular indexable insert designed for finishing operations in steel, offering a sharp cutting edge and low cutting forces for improved surface quality.

• Cermet grade NS9530 for superior finishing
• Sharp edge geometry for low cutting forces
• Triangular 60° form with 0.4 mm corner radius
• Cylindrical hole with single‑side countersink

Consistent finishing with a cermet cutting edge

The uncoated cermet grade NS9530 is optimised for finish turning of steel, where a sharp cutting edge and low cutting forces are essential. This composition promotes a fine surface finish and reduced burr formation during continuous cuts and small depths of cut. Compared with general‑purpose grades, the finishing grade lowers the tendency to form built‑up edge, which helps to keep tolerances stable and reduces downstream rework.

Secure seating and stable cutting geometry

A repeatable tool‑holder interface is essential for accurate turning. The triangular 60° geometry, combined with an 11° clearance angle and a nominal corner radius of 0.4 mm, provides predictable contact conditions and reliable edge strength during finishing passes. The insert is supplied with a cylindrical hole and a single‑side countersink (40°–60°), ensuring positive clamping and consistent axial position in compatible holders and boring bars. The plate thickness of 2.38 mm contributes to rigidity without compromising accessibility in confined setups.

Application scope and process benefits

Designed for both external and internal turning, the single‑sided chipbreaker on this insert supports chip control in continuous finishing cuts on steel. By selecting the NS9530 finishing grade and matching the chipbreaker to the workpiece and machining parameters, process planners can expect improved first‑pass quality and reduced secondary operations. The standard ISO format and size designation facilitate inventory management within an ISO system, allowing straightforward replacement and minimal machine downtime.

FAQ

What materials is this insert intended for?
The NS9530 uncoated cermet finishing grade is intended primarily for finishing operations in steel; the TPGT090204 NS9530 insert performs best where low cutting forces and a sharp edge are required.

How does the 0.4 mm corner radius affect the surface finish?
A 0.4 mm corner radius on the TPGT090204 NS9530 provides a balance between edge strength and a fine surface finish, reducing vibration while maintaining good profile accuracy.

Is the insert compatible with standard ISO triangular holders?
Yes, the TPGT090204 format follows the ISO geometry for triangular inserts; the cylindrical hole and countersink allow secure clamping in holders designed for this designation.

What benefit does the uncoated cermet grade NS9530 bring to finishing?
The NS9530 cermet offers a sharp edge and stable cutting behaviour for continuous finishing cuts, which leads to improved surface quality and fewer secondary finishing steps.

Which chipbreaker should be selected for interrupted cuts?
For interrupted or unstable cuts, a chipbreaker and grade combination different from the finishing NS9530 is usually advised; for continuous finishing the single‑sided chipbreaker on this insert provides good chip control.
