TPMT090202 AH6225 — ISO turning insert, triangular, 0.2 mm radius — Tungaloy

The TPMT090202 AH6225 is a triangular ISO insert designed for general turning, optimised for machining stainless steels with a sharp, durable cutting edge.

• ISO‑compliant triangular insert
• PVD‑coated AH6225 carbide grade
• 0.2 mm corner radius for fine finish
• With hole and countersink for secure clamping

Consistent cutting performance for stainless steels

The PVD‑coated carbide composition and the AH6225 grade combine to deliver a balance of sharpness and edge stability suited to stainless steels in medium machining. The coating improves wear resistance and helps maintain a consistent cutting edge under varying conditions, which reduces frequency of insert changes and supports predictable cycle times. The single‑sided chipbreaker controls chip formation, lowering the risk of long, tangled swarf and improving surface finish on external and internal turning operations.

Secure design for repeatable positioning and surface quality

A triangular geometry with a 60° included angle and corner radius 0.2 mm provides reliable strength while enabling good surface quality on finishing passes. The insert is 2.38 mm thick and features an 11° clearance angle, ensuring proper contact with the workpiece and preventing rubbing under typical turning feeds. The hole with cylindrical bore plus single‑side countersink (40°–60°) facilitates positive clamping in ISO holders and boring bars, minimising movement and improving repeatability across indexed edges.

Practical system benefits and application guidance

The insert is part of an ISO system: combine it with the appropriate external holder or boring bar, a matching shim/clamp set and the correct replacement screws to achieve optimal clamping and tool life. Selection of grade and chipbreaker should reflect workpiece material and process stability; AH6225 is recommended as a universal option for rostfreie Stähle (stainless steels) in environments requiring both a sharp cutting action and a robust edge. This approach reduces setup time and supports efficient production workflows while maintaining component quality.

FAQ

What materials is this insert suitable for?
The TPMT090202 AH6225 insert is designed primarily for stainless steels and performs well in medium turning operations where a balance of sharpness and edge stability is required.

How does the chipbreaker affect machining?
The single‑sided chipbreaker on the TPMT090202 AH6225 controls chip shape and evacuation, improving surface finish and reducing the risk of entangled swarf in turning applications.

Which clamping systems are compatible with this insert?
The insert's cylindrical hole with a single‑side countersink (40°–60°) is intended for ISO‑compliant external holders or boring bars using the standard shim/clamp and screw set listed in the system setup.

What are the key dimensions to check for holder compatibility?
Check the size (09), thickness (2.38 mm), included angle (60°) and clearance angle (11°) to ensure compatibility with the intended ISO holder and tolerance class.

Can this insert be used for internal as well as external turning?
Yes; the ISO triangular form and chip control make the TPMT090202 AH6225 suitable for both external and internal turning when mounted in an appropriate boring bar or holder.
