TPGT 090204 NS9530 indexable insert for turning — Tungaloy, triangle, finishing grade

The TPGT090204 NS9530 is an ISO-standard triangle indexable insert engineered for precision finishing of steel in both external and internal turning applications.

• Triangle ISO geometry, size 09
• Uncoated cermet NS9530 finishing grade
• 0.4 mm corner radius for fine edges
• 11° clearance and 60° included angle

Consistent finishing performance with low cutting forces

The insert delivers a stable finishing performance thanks to the uncoated cermet composition NS9530, which combines a sharp cutting edge with low cutting forces. This results in improved surface quality and reduced vibration during continuous cutting and light depth-of-cut operations. The chemical and microstructural characteristics of the cermet ensure edge integrity at finishing feed rates, so the machining process becomes more predictable and repeatable for high-quality components.

Geometry and clamping designed for compatibility and process reliability

ISO standardisation of the insert ensures compatibility by form, relief angle and tolerance class with a wide range of holders. The triangle geometry and 60° included angle permit three usable cutting edges per insert, while the cylindrical hole with one-sided countersink (40°–60°) secures repeatable seating and clamping. Specifying the correct holder profile and the matching clamp or adaptor guarantees correct seating and reliable chip evacuation for consistent cycle times.

Fine edge control and secure cutting for surface-critical parts

A 0.4 mm corner radius paired with 11° clearance supports a sharp effective cutting edge with controlled edge strength—especially beneficial for finishing steels where surface integrity matters. The single-sided chipbreaker is optimised for small depths of cut, promoting manageable chip forms and avoiding edge loading that could compromise finish. The 2.38 mm insert thickness contributes to rigidity and stability at the cutting zone, aiding dimensional accuracy on delicate finishing passes.

Selection guidance and system considerations for efficient planning

When integrating this insert into production, select the chipbreaker and grade to suit workpiece material, machining stability and feed strategy; the NS9530 grade is intended for finishing of steel with continuous cuts and small feed rates. Compatibility depends on holder shape, free clearance angle, size and thickness; confirm these parameters with component tolerances and the chosen toolholder.

FAQ

Which workpiece materials is this insert suited for?
The TPGT090204 NS9530 insert is designed primarily for finishing steel, with the uncoated cermet NS9530 grade providing a sharp edge and low cutting forces ideal for continuous cuts and small depths of cut.

What are the key geometric specifications of the insert?
The insert features a triangle geometry with a 60° included angle, a 0.4 mm corner radius, 2.38 mm thickness and size 09, specified to match ISO holders and clamps for secure seating.

Is the cutting material coated?
No, this is an uncoated cermet grade (NS9530), chosen for its ability to produce high-quality surface finishes with reduced cutting forces in finishing operations.

How does the hole and countersink affect mounting?
The cylindrical hole with a one-sided countersink (40°–60°) ensures repeatable positioning and reliable clamp engagement; compatibility still depends on holder form, tolerance and clearance, so matching to the toolholder is essential.

For which turning operations is this insert recommended?
This indexable insert suits precision finishing in both external and internal turning, especially where continuous cutting and small feeds are used to achieve superior surface finish.
