TPMT 16T304 AH6225 triangular ISO turning insert — Tungaloy

A TPMT 16T304 AH6225 ISO triangular turning insert engineered for external and internal turning in a wide range of stainless steels.

• ISO triangle insert, 60° geometry
• PVD-coated carbide AH6225 grade
• PS chipbreaker for controlled chips
• 0.4 mm corner radius for edge stability
• Cylindrical hole with 40°–60° countersink

Reliable edge life with a sharp, stable cutting geometry

The AH6225 grade is a PVD-coated carbide formulation designed to balance a keen cutting edge with wear resistance during medium turning operations. This combination reduces the frequency of edge changes and supports consistent dimensional accuracy over extended runs. The result is fewer interruptions for tool changeover and more predictable component quality. For those less familiar with coatings, PVD (physical vapour deposition) provides a thin, hard layer that improves abrasion resistance without compromising edge sharpness, making it suitable for varying stainless steel workpiece conditions.

Consistent chip control and surface finish from the PS chipbreaker

The integrated PS chipbreaker is tailored to produce short, manageable chips when machining stainless steels under typical turning parameters. Controlled chip formation reduces the risk of entanglement and protects the machined surface from damage, thereby lowering rework rates. The triangular 60° geometry and 0.4 mm corner radius contribute to predictable cutting forces, helping to maintain surface integrity and reduce vibration. When surface finish and process stability matter, matching chipbreaker and grade brings a clear efficiency gain in hourly output.

Straightforward integration into ISO tool systems for fast setup

The insert features a triangular plate form with a cylindrical hole and single-sided countersink (40°–60°) that accommodates common ISO-compatible holders. Compatibility to a holder depends on form, clearance angle (11°), tolerance class, clamping design, size and thickness; here the plate thickness is 3.97 mm and the nominal plate size is 16 mm. This design supports quick clamping and repeatable positioning, which shortens setup time and helps keep machine uptime high. If uncertainty exists about holder match or cutting data, a short consultation can clarify the correct clamping and cutting strategy.

FAQ

Is this insert suitable for machining stainless steels? The AH6225 grade on the TPMT16T304-PS insert is developed for stainless steels, offering a balance of edge sharpness and wear resistance for medium turning operations.

What does the PS chipbreaker deliver in practice? The PS chipbreaker on this insert promotes short, controlled chips and improved surface quality when paired with the appropriate cutting data for stainless steels, reducing the risk of chip-related interruptions.

Which toolholders are compatible with this insert? Compatibility depends on the holder's pocket form, clamping method, clearance angle and size; the TPMT16T304-PS fits ISO triangular 16 arrangements with a 3.97 mm plate thickness and the described hole/countersink configuration.

How does the PVD coating affect performance? The PVD-coated carbide combination enhances abrasion resistance while preserving a sharp edge, which supports longer intervals between indexings and more consistent workpiece tolerances.

Can the insert be used for finishing passes? With an appropriate cutting geometry and reduced depth or feed, the insert can achieve respectable finishes; the 0.4 mm corner radius and PS chipbreaker help maintain surface integrity during lighter cuts.
