TPMT16T308-PS AT9530 triangular turning insert (16T308) for turning – Tungaloy

The TPMT16T308-PS AT9530 is an ISO-standard triangular turning insert engineered for finishing and light machining of steel, emphasising superior surface quality and uniform tool wear.

• ISO triangular insert TPMT 16T308 format
• Cermet grade AT9530 for fine finishing
• 0.8 mm corner radius for excellent surface
• Cylindrical hole with 40°–60° countersink

High-quality cermet for improved finish and consistency

The coated cermet grade AT9530 delivers a clear benefit where surface quality is paramount. Designed for finishing and light machining of steel, this grade combines a wear-resistant coating with a stable substrate to produce a uniform wear pattern and consistent component quality over time. The material selection reduces microchipping and promotes predictable tool life, which supports process planning and reduces unplanned downtime. The result is improved first-pass yield and fewer rework cycles.

Geometry engineered for secure clamping and predictable chips

The insert’s triangular geometry with a 60° included angle and 0.8 mm corner radius balances edge strength and fine finishing capability. A relief of 11° ensures correct cutting engagement while the 3.97 mm thickness contributes to mechanical stability in the holder. The part is supplied with a cylindrical hole and a single‑side countersink (40°–60°) that facilitates secure clamping in compatible toolholders. The PS chipbreaker supports controlled chip formation during finishing passes, making chip evacuation more reliable and reducing risk of surface damage.

Practical compatibility and recommended applications

This ISO-format insert is intended for both external and internal turning operations in steel when the priority is surface finish rather than heavy material removal. Compatibility with a holder depends on form, relief, tolerance class, clamping method, size and thickness, so matching these parameters in the tool system is essential for achieving the advertised performance. When paired with a suitable ISO TPMT-capable holder, the insert provides a stable cutting edge and predictable behaviour for short-series production and finishing cuts.

Productivity and machining advice

Using a coated cermet insert in finishing frequently reduces the need for secondary polishing and can shorten cycle times by delivering acceptable surface roughness in a single pass. The combination of AT9530 coating and a carbide substrate gives a balance between edge life and surface integrity; select cut parameters that favour moderate feeds and finishing speeds to exploit the grade’s strengths. For interrupted cuts or heavy roughing, consider a more robust grade optimised for higher stock removal.

FAQ

Which machining tasks suit this insert best?
The TPMT16T308-PS AT9530 is optimised for finishing and light machining of steel, where surface finish and consistent wear are priorities.

How does the 0.8 mm corner radius affect results?
A 0.8 mm corner radius on the TPMT16T308-PS AT9530 increases edge strength and promotes a smoother surface, making it well suited to fine finishing passes.

Which holder features are required for correct fit?
Compatibility requires a holder that matches the ISO 16T308 form, the insert’s 11° relief, 16 mm size and 3.97 mm thickness; secure clamping is achieved via the cylindrical hole with the specified countersink.

Is the insert suitable for internal turning operations?
Yes, the TPMT16T308-PS AT9530 can be used for both external and internal turning, provided the holder geometry supports the triangular ISO insert form.

What performance can be expected regarding wear and surface quality?
The coated AT9530 cermet grade offers uniform wear and is focused on producing high surface quality during finishing; for heavier stock removal, a different grade is recommended.
