TPMT 130304 NS9530 turning insert – triangular 13 mm, uncoated cermet, Tungaloy

TPMT130304-23 NS9530 is an ISO‑standard turning insert designed for finishing operations on Stahl, combining a sharp cutting edge with a low cutting force geometry

• ISO‑standard triangular insert 13 mm
• Uncoated cermet grade NS9530 for finishing
• 0.4 mm corner radius and 11° clearance
• Cylindrical hole + single countersink 40°–60°

High-efficiency finishing for demanding turning operations

The NS9530 grade is an uncoated cermet developed for fine finishing of Stahl. Its formulation produces a sharp cutting edge and low cutting forces, which directly reduce burr formation and the need for rework. For continuous cutting and small depths of cut the result is a noticeable improvement in surface integrity and a reduction in cycle time. The insert’s geometry supports consistent chip formation and promotes predictable tool behaviour under stable machining conditions.

Geometry and machining stability that simplify process planning

With a triangular form and a nominal size of 13 mm, this ISO insert features a 0.4 mm corner radius and an 11° clearance angle, yielding a 60° included angle that suits fine finishing passes. The combination of these dimensions helps to maintain contact stability and minimise vibration when paired with a correctly specified holder or boring bar. Compatibility with the toolholder is governed by shape, clearance, tolerance class, clamping method, size and thickness; the ISO-standard design facilitates straightforward selection of matching holders.

Clear advantages from material and chip control

As an uncoated cermet grade, the insert favours low friction at the cutting edge and delivers excellent surface finish on Stahl at modest cutting speeds. The integrated chipbreaker style (designated 23) supports predictable chip formation during continuous cuts, which reduces the risk of built-up edge and helps maintain repeatable part quality. For operations prioritising cosmetic finish and tight dimensional tolerances, the cutting-material pairing and groove geometry of this insert provide both performance and process reliability.

System considerations and straightforward assembly

The insert forms part of an application system comprising an ISO insert, a compatible external holder or boring bar, a supporting shim/clamping set and replacement screws. The insert thickness of 3.18 mm, the cylindrical hole with a single‑side countersink (40°–60°) and the tolerance class must be checked against the chosen holder to ensure a secure clamping interface and correct rake/relief alignment. Selecting the proper clamping components improves repeatability and reduces downtime for index changes.

FAQ

What material is the TPMT130304-23 NS9530 best suited for?
The TPMT130304-23 NS9530 insert is optimised for finishing on Stahl, providing a sharp edge and low cutting forces for high-quality surface finishes.

How does the 0.4 mm corner radius affect part finish?
A 0.4 mm corner radius balances edge strength and surface quality: it reduces edge wear while producing a fine finish ideal for small-depth finishing passes.

Is the insert plated or uncoated?
The cutting grade is an uncoated cermet, chosen to provide a sharp edge and consistent surface results in continuous finishing operations.

What holder features are required for reliable clamping?
Reliable clamping requires a holder matching the insert form, clearance angle, tolerance class and thickness (3.18 mm); ensure the holder accepts a triangular 13 mm ISO insert and the specified clamping/shim set.

Can this insert be used for internal turning as well as external turning?
Yes, the ISO triangular geometry and chip control make the insert suitable for both external and internal turning applications, particularly where finishing and surface quality are priorities.
