TPMT 16T304 AH6225 — Turning insert, PVD‑coated carbide, 60° (Tungaloy)

The TPMT 16T304 AH6225 is an ISO‑standard triangular turning insert designed for external and internal turning of stainless steels, offering a balance of sharp cutting action and edge stability for medium machining and variable conditions.

• PVD-coated carbide grade AH6225
• Optimised for stainless steel turning
• 60° triangular geometry for versatility
• 0.4 mm corner radius for consistent edge life

High‑performance grade for reliable stainless steel machining

The PVD‑coated AH6225 grade combines a fine‑tuned coating process with a tough carbide substrate to provide a sharp yet stable cutting edge in demanding conditions. Designed as a universal solution for stainless steels, the grade delivers predictable wear behaviour during medium cutting operations and when conditions change, reducing the need for frequent tool changes. The balanced edge form supports consistent dimensional accuracy and contributes to extended tool life, which in turn helps maintain throughput on production lines.

ISO compatibility and secure clamping for simple integration

The insert follows ISO geometry and is compatible with standard indexable holders when matched by form, relief angle, tolerance class, fastening method, size and thickness. The triangular 60° shape and the cylindrical hole with one‑sided countersink (40°–60°) enable reliable seating and repeatable location in a wide range of external and internal turning holders. With a free angle of 11°, a plate thickness of 3.97 mm and a nominal size of 16 mm, the component integrates cleanly into existing setups, reducing setup time and simplifying inventory management for common ISO tool systems.

Consistent chip control, edge stability and economical uptime

Equipped with the PSS chipbreaker and a 0.4 mm corner radius, the insert delivers manageable chip formation and a robust cutting edge that withstands intermittent forces. These characteristics help produce a fine surface finish while limiting edge chipping under medium cutting conditions. The combination of chip control and grade stability improves process reliability and lowers overall machining costs by extending indexable life and reducing scrap rates, making the solution suitable for batch production or continuous turning operations.

FAQ

What materials is this insert designed for?
The TPMT16T304‑PSS AH6225 from Tungaloy is optimised for machining stainless steels, offering a grade and coating combination tailored for reliable performance in those alloys.

Which toolholders are compatible with this insert?
Compatibility depends on matching the ISO triangular form, relief angle, tolerance class, fastening and plate thickness; the insert fits standard ISO holders sized for a 16 mm triangular insert and the required clamping geometry.

How does the 0.4 mm corner radius affect performance?
A 0.4 mm corner radius provides a strong cutting edge that balances edge life and surface finish, helping to resist chipping while producing consistent component quality with moderate cutting parameters.

What chip control can be expected?
The PSS chipbreaker combined with the AH6225 grade delivers controlled chips for typical turning operations, aiding evacuation and improving surface condition under medium machining conditions.

What are the identifying product codes for ordering?
Order using the article number 6829896 or the manufacturer SKU TUN6829896; the product is listed as TPMT16T304‑PSS AH6225 (SKU 6829896‑Tungaloy).
