TCMT090204 NS9530 Tungaloy indexable insert for turning — triangular 60°, 0.4 mm radius

The TCMT090204 NS9530 is an ISO‑standard triangular indexable insert designed for finishing turning of steel, offering a sharp cutting edge, low cutting forces and a consistent surface finish.

• ISO‑standard triangular insert, 60° geometry
• Uncoated cermet grade NS9530 for fine finishing
• Sharp cutting edge for low cutting forces
• Cylindrical hole with single‑side countersink

Achieve superior surface finishes with low cutting forces

The uncoated cermet composition of the NS9530 grade is engineered for finishing operations on steel, delivering a sharp cutting edge that reduces built‑up edge and enables stable, continuous cutting. This results in a lower force requirement at the tool tip and an excellent surface finish on turned components. In practice, the combination of a fine‑grain cermet microstructure and the specified geometry supports small depth‑of‑cut finishing passes with minimal need for rework. The insert’s cutting edge stability reduces vibration and helps maintain repeatable dimensional accuracy across series production.

ISO compatibility for fast, reliable tool setups

The TCMT form follows ISO‑standard conventions so compatibility with holders is determined by geometry, clearance angle, tolerance class, fastening method, size and thickness. This standardisation simplifies tool selection and replacement: matching the 60° triangular geometry with the correct external holder or boring bar ensures secure clamping and predictable cutting orientation. For production environments, that predictability shortens set‑up time and reduces the variability between operators, contributing to a more efficient machining flow and higher first‑pass yields.

Secure mounting and finishing control for delicate operations

The insert features a cylindrical hole with single‑side countersink (40°–60°) which provides a reliable seating and repeatable clamping interface, helping to preserve the sharp cutting edge during index changes. The 0.4 mm corner radius offers a fine finishing radius suitable for profile detail and high surface quality, while the 2.38 mm plate thickness and size designation 09 support stable engagement in light finishing passes. For internal and external turning tasks, selecting the correct single‑sided chipbreaker and a holder matched to insert thickness ensures optimal chip control and consistent results, even on continuous cuts and small feeds.

Application focus and handling recommendations

Designed primarily for finishing turning of steel, the grade is best used where low cutting forces and high surface quality are priorities. While the NS9530 grade offers superior edge sharpness, it is optimised for continuous cuts and smaller depths of cut rather than heavy interrupted machining. For best performance, assemble the ISO‑standard insert into a compatible holder with the correct tolerance and clamping hardware, use appropriate cutting parameters for cermet materials, and consider coolant strategy according to the workpiece and holder stability. Tungaloy’s precision manufacturing ensures consistent edge geometry and productive tool life in serial operations.

FAQ

What materials is this insert suited for?
The TCMT090204 NS9530 insert is optimised for finishing the machining of steel, providing a sharp edge and low cutting forces for high‑quality surface finishes.

How does the NS9530 uncoated cermet grade behave compared with coated grades?
The uncoated cermet NS9530 emphasises edge sharpness and surface finish; unlike many coated grades, it is tailored for continuous finishing cuts and small feeds where minimal built‑up edge and fine surface quality matter most.

Which holder and clamping features are required for reliable use?
Compatibility depends on the holder matching the ISO triangular form, clearance angle, tolerance class, fastening type, size and thickness; the cylindrical hole with a single‑side countersink provides secure seating and repeatable clamping.

Can this insert be used for internal turning as well as external turning?
Yes; the insert is intended for both external and internal turning operations, with the chipbreaker and machining parameters chosen according to workpiece stability and required surface finish.

What cutting conditions are recommended for best results?
For finishing passes on steel, employ modest depths of cut and feeds appropriate for cermet grades, ensure stable clamping and use a holder that minimises overhang; coolant strategy should follow shop practice for the workpiece and machine stability.
