TNGG TNGG160402 NS9530 – Indexable turning insert with uncoated cermet and 0.2 mm nose radius, Tungaloy

TNGG160402 NS9530 is an ISO-standard triangular indexable insert designed for external and internal turning, optimised as a finishing grade for steels with continuous cuts.

• Uncoated cermet grade NS9530 for fine finishes
• 0.2 mm nose radius for precise contouring
• ISO triangular form TNGG160402 with hole
• Double-sided chipbreaker, suitable for continuous cuts

Consistent finishing with low cutting forces

The uncoated NS9530 grade delivers a combination of low cutting forces and high-quality surface finishes, making it suitable for finishing passes on steels where a sharp cutting edge is required. The small 0.2 mm nose radius reduces built-up edge and helps to preserve component tolerances while producing minimal vibration. For machining operations that prioritise surface integrity over heavy material removal, this insert provides a measurable advantage in process stability and repeatability.

Secure fit and straightforward holder compatibility

Compatibility is determined by the insert’s form, clearance angle, tolerance class, fastening and dimensions; the ISO geometry of this triangular plate ensures reliable seating in standard external holders or boring bars. The plate’s 4.76 mm thickness and 16 mm size meet ISO conventions, while the cylindrical hole and matching clamping sets or screws guarantee correct location and repeatable clamping force. This construction reduces set-up time and avoids misalignment that can compromise finish or insert life.

Material scope and machining performance

Although manufactured with a carbide backing for mechanical strength, the cutting grade is an uncoated cermet, optimised for steel finishing in continuous cutting conditions. The double-sided chipbreaker supports stable chip control during small depths of cut and continuous feed, helping to lower rework rates and improve throughput. The 60° insert geometry provides predictable corner behaviour and is suitable for both external profiling and internal turning tasks where a fine surface and tight dimensional control are required.

Practical advantages for workshop use

The indexable design allows economical rotation or replacement of cutting edges without regrinding, supporting consistent production runs and straightforward inventory management. Selecting the correct chipbreaker and grade in alignment with workpiece material and cutting parameters extends tool life and reduces downtime. Where tighter tolerances and fine surface quality are priorities, this finishing insert contributes directly to lower scrap rates and higher first-pass acceptance.

FAQ

What machining tasks is this insert best suited for?
The TNGG160402 NS9530 insert is optimised for finishing operations on steel in continuous cutting, offering low cutting forces and excellent surface quality.

How does the NS9530 grade affect tool life and finish?
The uncoated NS9530 cermet grade promotes a sharp cutting edge and low cutting forces, which typically results in superior surface finish and stable tool life in finishing applications.

Which holders are compatible with this triangular ISO insert?
Compatibility depends on holder form, clearance angle, tolerance class, fastening and size; the ISO TNGG form fits standard triangular turning holders and boring bars when matched correctly.

Can the insert be used for internal boring as well as external turning?
Yes, the triangular geometry and the 60° included angle make the insert suitable for both external profiling and internal turning tasks where a finishing grade is required.

What are the distinguishing geometric parameters to check before mounting?
Verify the 0.2 mm nose radius, 4.76 mm plate thickness, 16 mm size, 0° clearance angle, and the presence of a cylindrical locating hole to ensure proper fit and secure clamping.
