TPMT090204 NS9530 Tungaloy turning insert — uncoated cermet, 60° triangular

The TPMT090204 NS9530 is an ISO triangular indexable insert for turning, engineered as a finishing grade for continuous cuts in steels.

• Uncoated cermet grade NS9530 finish
• Sharp cutting edge for superior surface finish
• 0.4 mm corner radius, 60° triangular geometry
• Cylindrical hole with single‑side countersink

High-performance finishing for steel components

Built for finishing applications, this ISO turning insert delivers low cutting forces and an exceptionally fine surface thanks to the uncoated cermet composition and a deliberately sharp cutting edge. The NS9530 grade is formulated to promote stable chip formation and reduced built‑up edge during continuous turning, which translates into fewer rework cycles and consistent component quality. As a result, machining windows can be focused on achieving surface integrity and dimensional accuracy rather than compensating for tool limitations.

Precise geometry and secure clamping for repeatable results

The insert’s 60° triangular geometry and 0.4 mm corner radius provide a reliable balance between edge strength and finish capability, while the 11° clearance angle supports smooth chip flow. Compatibility with ISO holders depends on form, clearance angle, tolerance class, fastening method, size and thickness; the standardised design ensures straightforward replacement in existing tool systems. The central cylindrical hole with a single‑side countersink (40°–60°) guarantees stable clamping and repeatable seating, reducing vibration and enabling more consistent finish across batches.

Process benefits and recommended uses in production

Designed primarily for turning steels with small depths of cut and continuous feeds, this grade excels where surface quality is the priority. The combination of low cutting forces and an optimised chipbreaker on one side reduces tool deflection and helps maintain tight tolerances on external and internal diameters. In practice, selecting this insert for finishing passes minimises downstream polishing and inspection time, supporting faster throughput and predictable cycle times in production environments.

FAQ

What materials is this insert suitable for?
The NS9530 grade is intended for finishing in steels; the uncoated cermet composition provides low cutting forces and good surface quality when used for turning operations.

How does the 0.4 mm corner radius affect finishing?
A 0.4 mm corner radius offers a balance between edge strength and fine finish capability, reducing chatter and improving surface integrity during finishing cuts.

Is this insert compatible with standard ISO holders?
Compatibility depends on holder form, clearance angle, tolerance class, fastening and size; the insert follows ISO dimensions to facilitate replacement in matching external holders or boring bars.

What advantages does the uncoated cermet NS9530 provide over coated grades?
Uncoated cermet like NS9530 provides a very sharp initial cutting edge and lower cutting forces, which is beneficial for continuous finishing passes where surface finish is the priority.

Can this insert be used for internal turning as well as external turning?
Yes; the geometry and clamping design support both external and internal turning applications provided the correct holder or boring bar is selected.
