TPMT090204 AH6225 Tungaloy insert — ISO triangular turning insert, PVD-coated carbide, 11° clearance

A TPMT090204 AH6225 triangular turning insert designed for external and internal turning, optimised for stainless steels and medium cutting conditions

• PVD-coated carbide AH6225 for stainless steel
• ISO triangular insert, size 09, 2.38 mm thick
• Sharp yet stable cutting edge for medium cutting
• Cylindrical hole with 40°–60° countersink

Consistent cutting performance and material suitability

The insert delivers reliable machining when working with stainless steels, thanks to the PVD-coated surface and the AH6225 grade. The coating stabilises the cutting edge under fluctuating temperatures and varied cutting forces, while the carbide substrate supports repeatable performance. As a consequence, the component life becomes more predictable and the number of tool changes is reduced, supporting smoother production cycles and lower process interruptions.

Easy integration into ISO tooling systems

Designed to ISO dimensions, the insert offers quick interchangeability with matching turning holders and boring bars. The ISO conformity and triangular geometry (size 09) ensure straightforward replacement and alignment, while the 11° clearance promotes reliable chip flow and prevents rubbing. The cylindrical hole with one-sided countersink (40°–60°) secures the insert firmly in the clamp, reducing setup time and improving positional repeatability in batch production.

Practical application tips for turning operations

Suitable for both external and internal turning, the insert features a 0.4 mm corner radius and a 2.38 mm thickness that balance strength and finishing capability. The single-sided chipbreaker is tuned for medium cutting parameters, helping to form stable chips under typical lathe feeds and speeds. For unstable setups or interrupted cuts, selecting a holder with higher rigidity and adjusting cutting parameters will extend tool life and maintain surface quality.

Operational advantages that support productivity

Using this grade and form promotes greater productivity through steadier cutting behaviour and improved chip control, reducing downtime caused by tool failures. The insert’s combination of a sharp geometry and a robust substrate contributes to long-term process stability, while the universal AH6225 grade keeps stock handling simpler across mixed stainless-steel work. Overall, the solution is cost-effective for shops seeking dependable, repeatable turning performance.

FAQ

What materials is this insert best suited for?
The TPMT090204 AH6225 insert is formulated primarily for stainless steels, offering a balance of sharpness and edge stability for medium cutting conditions.

Will this insert fit existing ISO triangular holders?
Yes. The TPMT090204 follows ISO dimensions and secures with a cylindrical hole and countersink, making it compatible with matching ISO triangular holders when the holder’s form and tolerance class correspond.

What corner radius and thickness does the insert offer?
This insert has a 0.4 mm corner radius and a 2.38 mm plate thickness, suitable for a mix of finishing and general turning tasks.

How does the AH6225 grade affect chip formation?
The AH6225 PVD-coated grade promotes stable chip formation under variable conditions, improving chip control and reducing the likelihood of built-up edge on stainless-steel workpieces.

Is the insert single- or double-sided?
The design is single-sided with a one-sided chipbreaker; the TPMT090204 AH6225 insert provides a defined cutting edge on its active side for targeted performance.
