TPMT 090204 NS9530 — Tungaloy indexable turning insert for finish turning, 60° triangle

TPMT 090204 NS9530 is a triangular ISO indexable insert designed for finish turning applications, providing a sharp cutting edge and stable performance on continuous cuts.

• ISO triangular insert size 09
• Uncoated cermet finishing grade NS9530
• 11° relief angle for low cutting forces
• Central hole with countersink for secure clamping

Precision finishing for demanding turning tasks

The insert is engineered as a finish-grade uncoated cermet to deliver exceptionally low cutting forces and a sharp edge geometry. This combination reduces vibration at small depths of cut and improves surface integrity on steel components. The construction supports continuous cutting conditions where consistent surface finish and dimensional stability are priorities. Compatibility with ISO-designated holders assures repeatable clamping and predictable performance in production environments.

Designed for reliable clamping and repeatability

The triangular form with a central cylindrical hole and one-sided countersink (40°–60°) provides secure and reproducible seating in compatible toolholders. Compatibility is determined by the insert shape, relief angle, tolerance class, attachment method, size and thickness, so selection of the correct holder or boring bar is essential for optimal results. The 2.38 mm plate thickness and the defined tolerance class help maintain rigidity in the tool assembly, supporting consistent chip formation under steady feed conditions.

Optimised geometry and chip control for improved productivity

A single-sided chipbreaker and a corner radius of 0.4 mm balance edge strength with the capacity to produce fine, easily managed chips during finishing cuts. The 11° relief angle reduces rubbing and minimises cutting forces, which is particularly beneficial when machining steels on medium- to high-stiffness setups. The result is reduced tool wear and a higher likelihood of meeting tight surface roughness specifications without frequent edge dressing.

Application guidance and selection rationale

The NS9530 grade is suitable as a finishing sort for steels where a sharp edge and high surface quality are required; it is optimised for continuous cutting and small depths of cut rather than interrupted operations. When replacing or specifying inserts, verify holder compatibility with the ISO designation and the insert’s geometric data — size 09, 60° included angle, 2.38 mm thickness, and the central hole configuration — to ensure accurate seating and clamping. Proper selection enhances process stability and maximises the productive life of the cutting edge.

FAQ

What materials is this insert intended for?
The NS9530 finishing grade is formulated for steel machining; the TPMT 090204 NS9530 insert excels in producing high surface quality on continuous steel turning operations.

Which toolholders fit this ISO insert?
ISO-compatible turning holders and boring bars designed for triangular TPMT 090204 inserts with size 09, 2.38 mm thickness and a central hole with countersink will provide correct seating and clamping.

What cutting conditions suit the NS9530 grade?
NS9530 is optimised for continuous cutting and small depths of cut where a sharp edge and low cutting forces improve surface finish and dimensional control.

How does the 0.4 mm corner radius affect the finish?
A 0.4 mm corner radius offers a balance between edge strength and fine surface generation, yielding better finish quality while maintaining sufficient edge durability for finishing passes.

Is this insert suitable for interrupted cuts?
The insert is primarily intended for continuous turning; interrupted cuts may demand a different grade or geometry better suited to impact resistance.
