Universal grade AH725 for steel and stainless steels
Triangular 60° insert with 0.4 mm corner radius
ISO-compatible with cylindrical hole and countersink

Durable grade for consistent chip control and process security

The AH725 grade combines a PVD-coated carbide substrate with an optimised structure that promotes stable chip formation and reliable edge integrity in a wide range of steels, including stainless steels. This universality reduces tool inventory by covering many common workpiece materials, while the PVD layer improves resistance to abrasive and adhesive wear. The result is longer stable life in interrupted cuts and variable material batches, which supports predictable cycle times and reduces unexpected stoppages. The insert designation TPMT130304-PSS AH725 signals a standardised geometry for straightforward replacement in ISO holders.

Precision geometry and ISO compatibility for repeatable seating

The triangular shape with a 60° included angle and a 0.4 mm corner radius provides a balanced combination of strength and cutting edge accessibility, making it suitable for both finishing and light roughing passes. The insert thickness of 3.18 mm and the central cylindrical hole with a one-sided countersink (40°–60°) ensure secure clamping and repeatable positioning in compatible holders. Compatibility depends on form, clearance angle, tolerance class, mounting method, size and thickness, so pairing the insert with a matching shim, clamping set and replacement screws is vital for achieving repeatable accuracy and surface finish.

Chipbreaker design and application benefits for productivity

The PSS chipbreaker is tailored for external and internal turning operations where chip control and unclogged evacuation are essential, particularly in compact tooling setups and where process reliability is critical. By promoting predictable chip shapes and evacuation, the chipbreaker reduces the risk of re-cutting and tooling damage, which lowers downtime and tooling costs over time. For workshops seeking a practical balance between productivity and tool life, this insert supports shorter setup times, fewer tool changes and consistent part quality when used with an appropriate holder and clamping system.

FAQ

What materials is this insert designed for?
This insert in grade AH725 is engineered for machining a broad spectrum of steels and stainless steels, offering dependable performance where material mixes occur.

How does the PSS chipbreaker affect machining?
The PSS chipbreaker shapes and breaks chips reliably during turning, improving evacuation and reducing the likelihood of re-cutting or tool damage in confined tool geometries.

Which holders and accessories are required for correct use?
Correct seating requires an ISO-compatible turning holder, a matching shim or clamping set and the recommended replacement screw; compatibility is determined by form, clearance angle, tolerance class, size and thickness.

Is the insert suitable for finishing passes?
Yes; the 0.4 mm corner radius and 60° geometry allow controlled finishing cuts while still providing adequate edge strength for light roughing where required.

How does the AH725 grade contribute to process stability?
AH725 combines a robust carbide substrate with a PVD layer to resist abrasion and edge chipping, leading to consistent tool life and higher process reliability in varied production environments.
