TCMT 16T304 AH6225 – ISO turning insert by Tungaloy (PVD-coated carbide, 0.4 mm corner radius)

TCMT16T304 AH6225 is a triangular ISO turning insert designed for external and internal turning applications, optimised for rostfreier Stahl and medium machining tasks.

• PVD-coated carbide for high wear resistance
• Optimised for rostfreier Stahl turning
• One-sided chipbreaker for controlled chips
• Triangular ISO insert with 0.4 mm corner radius

Reliable cutting performance for consistent production

The combination of a PVD-coated carbide substrate and the AH6225 grade delivers a balance between a sharp cutting edge and edge stability, which directly improves process consistency. This chemistry and coating support longer tool life under variable conditions and reduce unscheduled tool changes, thereby improving machine uptime. For shops working with rostfreier Stahl, the insert’s robustness helps maintain dimensional accuracy and surface finish over longer tool cycles.

Design choices that simplify setup and compatibility

Supplied as an ISO-standard triangular insert, the geometry (16 mm size, 60° included angle) and the 0.4 mm corner radius provide predictable cutting engagement and robust strength at the corner. The insert is finished with a cylindrical hole and a single-sided countersink (40°–60°) for secure mounting; compatibility with toolholders is determined by form, clearance angle, tolerance class, fastening arrangement, size and thickness. The 7° clearance angle allows reliable chip formation while protecting the cutting edge in interrupted cuts.

Chip control and process efficiency

The single-sided chipbreaker is engineered to stabilise chip flow during turning, improving surface quality and reducing the risk of chip entanglement. Better chip control reduces cycle interruptions and cleaning time at the machine, which leads to measurable productivity gains. Choosing the appropriate chipbreaker and the AH6225 grade for medium machining of rostfreier Stahl supports consistent cutting forces, which in turn helps to extend insert life and reduce tooling costs per component.

Practical selection and handling advice

Select the insert in combination with a matching holder and clamping set to ensure correct seat and stable engagement; the ISO standardisation of the insert simplifies cross-referencing and replacement. For best results, match the cutter geometry and the chipbreaker style to the material condition and the machining parameters. Store inserts in their original packaging to protect the cutting edges, and inspect mounting screws and the backing pad for wear when making replacements to maintain repeatable performance.

FAQ

What materials is this insert suited for?
This insert is designed primarily for machining rostfreier Stahl; the AH6225 PVD-coated carbide grade offers broad applicability for medium turning tasks in that material.

How does the chipbreaker affect performance?
The one-sided chipbreaker on the TCMT16T304 AH6225 insert improves chip formation and evacuation, resulting in better surface finish and fewer interruptions during turning.

Is the insert compatible with standard ISO holders?
Yes, the insert follows ISO geometry; compatibility depends on matching form, clearance angle, tolerance class, fastening, size and thickness to the holder.

What mounting features should be checked before use?
Ensure the cylindrical hole and single-sided countersink align with the holder’s clamping system, and verify that the seating surface and screws are in good condition to maintain stability.

Can this insert be used for both external and internal turning?
Yes, the insert is suitable for both external and internal turning operations when paired with an appropriate toolholder and stable machining setup.
