TPMT 130308 AH6225 Wendeplatten - Tungaloy

Take advantage of the combination of a PVD‑coated carbide grade (AH6225) and a sharp yet stable cutting edge for reliable medium‑duty turning in stainless steels; compatibility with ISO holders ensures straightforward integration into existing tool systems — order directly via Metav Werkzeuge or consult our specialists for application guidance.

TPMT130308 AH6225 – ISO triangular turning insert, PVD‑coated carbide by Tungaloy (0.8 mm radius, 60°)

A TPMT130308‑PM AH6225 indexable turning insert designed for external and internal turning, optimised for machining stainless steels and adaptable to a wide range of shopfloor conditions

• PVD‑coated carbide AH6225 for rostfreier Stahl
• 0.8 mm nose radius for precise form control
• 60° triangular geometry for versatile turning
• Compatible with ISO holders and clamping systems
• Cylindrical hole with single‑side countersink 40°–60°

Proven grade and coating for consistent stainless‑steel results

The combination of a PVD‑coated surface and the AH6225 carbide grade yields a cutting edge that balances sharpness with robustness. This composition is tailored for machining stainless steels, providing improved wear resistance and thermal stability compared with uncoated grades. For production environments with variable cutting parameters, this mix reduces edge chipping and supports reproducible surface quality. The result is less frequent index changes and a steadier process window for serial turning operations.

Geometry and system compatibility that simplify tool planning

With a 60° triangular form, 0.8 mm nose radius and 11° clearance, the insert offers a familiar geometry that fits standard ISO toolholders when matched by form, tolerance class, clamping and thickness. The plate thickness of 3.18 mm and the 13 mm size make the component mechanically robust while remaining suitable for compact holders and boring bars. The cylindrical hole with a single‑side countersink (40°–60°) secures reliable clamping and repeatable seating, minimising runout and improving repeatability across production batches.

Practical benefits in everyday turning and tool management

Integrated into a system consisting of the insert, a compatible external holder or boring bar, a shim/clamping kit and replacement screws, this solution streamlines tool change and inventory management. The PM chipbreaker geometry supports medium cutting depths and helps to control chip formation in ductile, work‑hardening stainless grades. For workshop planners, the main advantages are predictable tool life, stable chip control and reduced downtime — factors that contribute to consistent part quality and cost efficiency over time.

FAQ

What materials is this insert suitable for?
The TPMT130308‑PM AH6225 is formulated primarily for rostfreier Stahl (stainless steels); the AH6225 grade and PVD coating are optimised for such alloys and for conditions requiring a sharp, stable cutting edge.

How does the PM chipbreaker influence performance?
The PM chipbreaker supports medium cutting depths and promotes stable chip formation during turning, which helps to avoid entanglement and improves surface finish when machining stainless steels with the TPMT130308 insert.

Which toolholders are compatible with this insert?
Compatibility depends on matching the ISO form, clearance angle, tolerance class, clamping method, size and thickness; when those parameters align, the TPMT130308‑PM fits standard ISO external holders and boring bars.

What is the benefit of the cylindrical hole with a countersink?
The cylindrical hole with a single‑side countersink (40°–60°) enables secure clamping and consistent seating, reducing runout and ensuring repeatable positioning for the TPMT130308 family.

Can this insert be used for internal turning?
Yes, the geometry and size make the insert suitable for both external and internal turning applications, provided a compatible boring bar or internal holder is used.
