TPMT 090204 NS9530 — Tungaloy turning insert, ISO triangular, fine finishing

TPMT090204 NS9530 Tungaloy is an ISO-standard triangular indexable insert designed for turning operations where low cutting forces and superior surface finish are required.

• Cermet grade NS9530 for fine finishing
• ISO TPMT 090204 triangular insert design
• Sharp cutting edge for low cutting forces
• Cylindrical hole with chamfer for secure clamping

Exceptional finish and reduced cutting forces for steel turning

The uncoated cermet NS9530 is formulated for finishing applications on steel, delivering a sharp cutting edge that reduces cutting forces and promotes an improved surface finish. Lower cutting forces lead to reduced spindle load and can delay flank wear, which helps to maintain dimensional accuracy during continuous turning. The combination of the material properties and geometry is aimed at small depths of cut and stable, uninterrupted cutting, so operators can expect predictable surface quality on turned components.

Reliable seating and simplified tool selection for productivity

Built to ISO dimensions, compatibility depends on form, relief angle 11°, tolerance class, attachment type, size and thickness; this makes selection straightforward and reduces setup time. The triangular form and the cylindrical hole with single-sided countersink (40°–60°) provide secure clamping with standard holders and boring bars. Clear ISO coding and standardised geometry mean interchangeability across tool systems, so machining centres and lathes benefit from reduced tooling complexity and faster changeovers.

Geometry tuned for stability and consistent chip control

The insert’s geometry combines a 60° included angle with a 0.4 mm corner radius and a plate thickness of 2.38 mm, offering a balance between edge strength and the fine cutting action required for finishing. The one-sided chipbreaker supports controlled chip formation in continuous cuts, reducing the likelihood of built-up edge and improving repeatable surface quality. These parameters help maintain component tolerances and reduce the need for secondary finishing operations.

System integration and expected operational behaviour

As part of a tooling system the insert pairs with a matching external holder or boring bar, plus underlay/shim sets and replacement screws as required. The modular setup supports quick insert indexing and easy maintenance, which contributes to steady production flow and predictable tool-life planning. For demanding finishing tasks, the ISO triangular format and grade selection help to maximise productivity while conserving machine resources.

FAQ

Is this insert suitable for finishing steel components?
Yes. The TPMT090204 NS9530 insert is a finishing grade optimised for steel, offering a sharp cutting edge and low cutting forces that support improved surface quality in finishing passes.

What holders are compatible with this ISO insert?
Compatibility is determined by holder form, relief angle, tolerance class, attachment and thickness; standard TPMT-compatible external holders and boring bars will accept the TPMT090204 geometry when dimensions and clamping match.

Does the insert have a chipbreaker and what is its effect?
The plate includes a one-sided chipbreaker designed to promote controlled chip formation during continuous cuts, which helps to avoid built-up edge and stabilise surface finish.

How does the 0.4 mm corner radius affect machining?
A 0.4 mm radius provides a compromise between a fine cutting action for finishing and sufficient edge strength to resist edge chipping, helping to maintain dimensional accuracy on turned parts.

Are spare screws and underlay required for mounting?
A typical system setup comprises the ISO insert, a matching external holder or boring bar, underlay/shim set and replacement screws; these components ensure secure clamping and repeatable positioning.
