TPMT 090204 AH6225 TPMT — Turning insert (ISO triangular, 60°) by Tungaloy

A TPMT 090204 AH6225 indexable turning insert for ISO-compliant external and internal turning, designed for medium machining of rostfreier Stahl.

• PVD-coated carbide AH6225
• Optimised for rostfreier Stahl
• 60° triangular insert geometry
• Cylindrical hole with single-side countersink

High-performance grade for rostfreier Stahl with consistent edge stability

The insert combines a PVD-coated carbide substrate with the universal AH6225 grade to deliver a balance of sharpness and edge strength suited to medium cutting conditions on rostfreier Stahl. The coating reduces built-up edge and improves wear resistance during interrupted cuts and variable conditions, while the carbide core maintains dimensional stability. This results in fewer tool changes and a more reliable cycle time for batch and single-piece production.

Geometry and edge design that improve process security

The 60° triangular form and a 0.4 mm corner radius provide a stable cutting edge for general turning tasks. The insert features a single-sided chipbreaker that is matched to the AH6225 grade to control chip formation and evacuation, reducing the risk of entanglement and improving surface finish. With an 11° relief angle, the geometry supports predictable cutting forces and repeatable tool performance across a range of feed and speed settings.

Secure clamping and straightforward machine integration

Designed as an ISO-format indexable insert, the item offers a cylindrical hole + single-side countersink (40°–60°) for positive location and reliable clamping in compatible holders. The 2.38 mm thickness and standard 09 size ensure mechanical stability during side forces typical of external turning. As part of a system consisting of the insert, matching external holder or boring bar, and clamping set, selection focuses on form, relief, tolerance class and size to guarantee compatibility and repeatable results.

FAQ

What materials is this insert best suited for?
The TPMT 090204 AH6225 insert is formulated for machining rostfreier Stahl; the AH6225 grade and PVD coating provide wear resistance and a controlled cutting edge for that material family.

How does the chipbreaker affect machining performance?
The single-sided chipbreaker on this insert promotes consistent chip control and evacuation, which helps to maintain surface quality and reduce the likelihood of chip-related interruptions when using the Tungaloy TPMT 090204 AH6225 indexable insert.

Is the insert compatible with standard ISO turning holders?
Yes — the insert follows ISO geometry for triangular inserts and the cylindrical hole with countersink ensures secure clamping in compatible external holders and boring bars when the holder matches form, clearance angle, tolerance and size.

What cutting edge features contribute to tool life?
The combination of PVD-coated carbide, a stable 0.4 mm corner radius and a designed cutting edge in the AH6225 grade increases resistance to chipping and wear, resulting in improved tool life under medium turning conditions.

Which part number should be used when ordering?
Order using the article number 6829887 or manufacturer SKU TUN6829887 for the Tungaloy TPMT 090204 AH6225 insert
