TNMG 160408 AT9530 — Indexable turning insert for finishing by Tungaloy

The TNMG160408 AT9530 is an ISO indexable insert intended for finishing and light turning of steel, optimised to deliver improved surface quality and steady wear behaviour.

• Coated cermet grade AT9530 for fine finishing
• ISO TNMG160408 triangular insert, 60° cutting angle
• Double-sided chipbreaker with cylindrical hole

High-precision finishing from a cermet grade designed for surface quality

The insert’s coated cermet composition, identified as AT9530, is engineered specifically for finishing and light machining of steel. Cermet combines ceramic hardness with metallic toughness, which reduces built-up edge formation and supports a consistent surface finish during finishing passes. The controlled wear characteristics of the grade mean more predictable change intervals and less variation in part quality over a production run, aiding process stability and repeatable component finish.

Easy integration into ISO TNMG tool systems for reliable setup

As an ISO 160408 format, the triangular insert fits holders and tool posts that match the TNMG form and size; compatibility is determined by holder shape, clearance angle, tolerance class, fastening method, size and thickness. The standardised geometry simplifies tool procurement and replacement logistics. Specified dimensions (16 mm inscribed circle, 4.76 mm thickness) and the 0° clearance angle make the part straightforward to verify against existing fixtures and reduce setup uncertainty in small-batch and serial operations.

Geometry and chip control that reduce downtime and improve part finish

The insert features a 0.8 mm corner radius and a 60° triangle form, balancing edge strength with the ability to produce fine surface textures in finishing cuts. The double-sided chipbreaker enables two usable cutting edges per pocket, and the cylindrical hole secures consistent clamping and repeatable seating. Together these design elements lower indexing frequency and help maintain consistent cutting conditions, which benefits throughput and lowers total process cost per part.

Recommended use cases and selection guidance for turning operations

This grade and geometry are best applied to final passes and light stock removal where surface quality and dimensional consistency are priorities. Select the chipbreaker and grade to match the workpiece material and machine/tooling stiffness; for less rigid setups, favour stable clamping and conservative feeds to exploit the AT9530’s wear characteristics. For internal and external turning where a fine finish is required, this insert offers a cost-effective way to achieve consistent results with minimal process variation.

FAQ

What applications are best for this insert?
The TNMG160408 AT9530 indexable turning insert is intended for finishing and light turning of steel, where a high-quality surface finish and uniform wear are required.

Which holders are compatible with ISO 160408 inserts?
Compatibility depends on holder form, clearance angle, tolerance class, fastening and plate thickness; match the holder to the ISO TNMG form and the insert’s 4.76 mm thickness.

How does the AT9530 grade affect tool life?
The AT9530 coated cermet is formulated for steady wear and improved surface finish, so it tends to produce predictable wear patterns and consistent component quality over extended runs.

How many usable edges are available per insert?
With a double-sided chipbreaker and triangular geometry, the insert offers multiple indexing positions; exact edge count depends on the holder and mounting method.

What does the 0.8 mm corner radius influence in turning?
A 0.8 mm corner radius balances corner strength and finish capability, helping to achieve smooth surfaces while maintaining an adequately robust cutting edge.
