TCMT 110204 NS9530 — ISO triangular indexable insert for finishing turning, Tungaloy

The TCMT110204 NS9530 is an ISO-standard triangular indexable insert optimised for finishing operations on steel, offering a sharp cutting edge and low cutting forces for continuous cuts and small depths of cut.

• ISO triangular insert, 60° geometry
• Uncoated cermet NS9530 for finishing
• Sharp cutting edge, low cutting forces
• Cylindrical hole with countersink for secure clamping

Precision finishing tailored to steel turning

The uncoated cermet grade NS9530 is specified for fine finishing on steel, delivering a sharp cutting edge that reduces cutting forces and improves surface quality during continuous cuts and small depths of cut. This material selection aims to balance edge retention and surface integrity: the cermet substrate provides the sharpness required for light passes while maintaining dimensional stability. For workshops seeking consistent surface finish, the result is a predictable part quality with fewer rework cycles and reduced secondary operations.

Secure clamping and simple holder compatibility

Compatibility with toolholders is determined by form, rake angle, tolerance class, fixation, size and thickness. The insert’s cylindrical hole with a one-sided countersink (40°–60°) ensures rigid and repeatable clamping in standard ISO seats, while the 2.38 mm thickness and 11-size designation fit common external holders and boring bars. The 0.4 mm corner radius offers a compromise between edge strength and finishing quality; when paired with the 7° relief angle, it helps to reduce rubbing and minimise built-up edge on long-running operations.

Reliable productivity with a finishing-focused geometry

The single-sided chipbreaker and triangular outline provide straightforward indexing and modest chip control suitable for finishing passes. As part of a conventional system—insert, compatible external holder or boring bar, and the appropriate shim/clamp set—the component integrates smoothly into existing tool inventories. The design supports efficient process flow by enabling quick indexing and repeatable set-up, which contributes to reduced machine downtime and consistent component tolerances when machining rotational parts.

FAQ

Which materials is this insert suitable for?
The NS9530 uncoated cermet is designed primarily for finishing on steel; its sharp cutting edge and low cutting forces make the insert particularly suitable for steel finishing operations.

How does the insert secure to the holder?
The insert uses a cylindrical hole with a one-sided countersink (40°–60°) to ensure secure clamping in ISO-compatible holders, providing repeatable seating and stable cutting conditions.

Is this insert suitable for internal and external turning?
Yes, the triangular form and standard ISO designation allow use in both external and internal turning applications when paired with the appropriate holder or boring bar.

What cutting conditions are recommended for the NS9530 grade?
This grade is optimised for finishing with continuous cuts and small depths of cut; its characteristics favour low cutting forces and high surface quality rather than heavy roughing passes.

How does the 0.4 mm corner radius affect the finish?
A 0.4 mm corner radius balances tool edge strength and surface quality: it helps maintain a sharp profile for fine finishes while offering sufficient robustness against minor vibrations.
