TPGT090202 NS9530 triangular ISO turning insert, uncoated cermet, 0.2 mm radius — Tungaloy

A TPGT090202 NS9530 ISO triangular indexable insert engineered for finishing turning of steel, optimised for continuous cuts and high surface quality

• NS9530 uncoated cermet finishing grade
• 0.2 mm corner radius for fine surface quality
• 11° relief angle for low cutting forces
• Cylindrical hole with single-sided countersink

High-quality finishing with reduced cutting forces

The uncoated cermet NS9530 is designed as a finishing grade for steels, offering a sharp cutting edge and low cutting forces that contribute directly to improved surface quality and dimensional stability. As a consequence of the cermet composition, friction at the cutting zone is reduced compared with some coated grades, which benefits continuous cutting operations and small depths of cut. This insert is therefore suited to applications where a fine surface and consistent repeatability are required.

Reliable fit and secure clamping in ISO systems

The triangular ISO shape and the cylindrical hole with a one-sided countersink (40°–60°) ensure precise seat alignment and stable clamping in compatible holders. The 11° relief angle is matched to standard turning holders, which helps lower flank contact and reduces cutting forces during finishing passes. Designers and operators will appreciate the reproducible positioning that reduces setup variation and supports steady-cycle machining.

Geometry tailored for consistent surface finish

With a 0.2 mm corner radius, the insert balances edge strength and the ability to produce fine finishes on external and internal turning operations. The single-sided chipbreaker geometry is optimised for continuous chips and stable chip flow when matched to the material and cut parameters. Selecting this grade and geometry leads to fewer rework cycles and a higher first-pass yield in precision components.

Practical selection and process guidance

For turning steels with continuous cuts and modest depths of cut, this ISO triangular insert delivers the best results when used with a suitably rigid holder and correct feed speeds for finishing. The insert forms part of a system that includes the matching outer holder or boring bar, a shim/clamp set and replacement screws; ensuring the complete assembly meets tolerance and form requirements increases process reliability and tool life.

FAQ

What steels is this insert suited to? This TPGT090202 NS9530 insert is a finishing grade optimised for steels and delivers low cutting forces and high surface quality when used in continuous turning.

Can the insert be used for internal turning? Yes, the triangular ISO geometry of the insert supports both external and internal turning applications when mounted in an appropriate boring bar or holder.

How does the cylindrical hole with countersink improve performance? The cylindrical hole with a one-sided countersink (40°–60°) provides precise seating and secure clamping, which improves repeatability and reduces the risk of movement during finishing cuts.

Is the NS9530 grade coated? No, NS9530 is specified as an uncoated cermet finishing grade, chosen for a sharp edge and reduced friction on steel finishing operations.

Which chipformer is fitted to this insert? The insert is supplied with a single-sided chipbreaker, suited to stable, continuous chips typical of finishing passes in steels.
