TCMT 090202 NS9530 — ISO triangular indexable turning insert for finishing by Tungaloy

The TCMT090202 NS9530 is an ISO triangular indexable insert designed for finishing operations in steel turning, providing a fine cutting edge and low cutting forces for continuous, small-depth cuts.

• ISO triangular insert TCMT 090202 NS9530
• Uncoated cermet for superior surface finish
• Sharp cutting edge for low cutting forces
• Cylindrical hole with single-sided countersink

Achieve consistent finishing results with a dedicated cermet grade

This finishing grade is engineered around an uncoated cermet substrate that combines wear resistance with a keen, stable cutting edge. The result is reduced cutting forces and a markedly improved surface finish on steel components, especially in continuous cutting conditions and small depths of cut. For operators seeking predictable, repeatable results, the insert’s geometry supports stable cuts and minimises the need for subsequent polishing or rework.

Easy integration with ISO holder systems and secure clamping

Conforming to ISO standards, the insert integrates smoothly into established turning toolholders; compatibility is governed by form, clearance angle, tolerance class, mounting, size and thickness. Key dimensional details such as the 60° geometry, 0.2 mm corner radius and 2.38 mm plate thickness ensure reliable seating and consistent chip control. The cylindrical hole with a single-sided countersink (40°–60°) secures the insert with standard clamps and replacement screws, reducing setup time and enhancing process stability.

When this finishing grade is the right choice for process optimisation

Choose a cermet finishing grade when the priority is high surface quality at low cutting forces, for materials that respond well to continuous cuts. Compared with some coated grades, an uncoated cermet offers a sharper edge and lower tendency to built-up edge in finishing passes, which helps achieve tighter tolerances and superior part appearance. The single-sided chipbreaker suits applications where predictable chip formation and evacuation contribute directly to productivity and component quality.

FAQ

Is this insert compatible with standard ISO triangular turning holders?
The TCMT090202 NS9530 insert follows ISO geometry for triangular inserts and fits holders designed for a 60° TCMT 09 insert with the corresponding tolerance class and clamping arrangement.

What materials is this grade best suited to machine?
NS9530 is a finishing cermet grade optimised for steel; the TCMT090202 NS9530 delivers low cutting forces and high surface quality in continuous finishing cuts on steel.

How does the uncoated cermet compare to coated carbide for finishing?
An uncoated cermet like NS9530 offers a sharper edge and improved surface finish in finishing operations compared with many coated carbides, particularly where small depths of cut and continuous feeds are used.

What clamping and hole specification does the insert require?
The insert features a cylindrical hole with a single-sided countersink (40°–60°) and is intended to be secured with standard clamps and screws compatible with TCMT 09 geometry.

When should the 0.2 mm corner radius be preferred?
A 0.2 mm corner radius is recommended for fine finishing passes where a balance of edge strength and minimal tool mark is required to achieve the desired surface quality.
