TCMT 16T308 AH6225 Turning insert (ISO) — Tungaloy

The TCMT16T308 AH6225 is an ISO triangular indexable insert designed for external and internal turning, offering a sharp yet stable cutting edge suited to machining stainless steels under medium cutting conditions.

• PVD-coated carbide AH6225
• Optimised for rostfreie Stähle
• 60° triangular geometry for rigidity
• Cylindrical hole with 40°–60° countersink

Consistent cutting performance for stainless steels

The insert combines a PVD-coated carbide substrate with the AH6225 grade to provide a balance between edge sharpness and wear resistance. This composition reduces built-up edge formation common with corrosion-resistant alloys, delivering more consistent surface finish and fewer interruptions for tool changes. The design supports medium machining and variable conditions, which translates into higher net productivity and predictable tool life when matched with a suitable cutting strategy.

Precision geometry and secure clamping for repeatable results

The 60° triangular geometry and 0.8 mm corner radius create a stable cutting platform that resists vibration and maintains dimensional accuracy. With a plate thickness of 3.97 mm and a 7° relief angle, the insert is engineered for secure seating in ISO-compatible holders; the insert’s cylindrical hole with single-sided countersink (40°–60°) ensures consistent clamping and repeatability across tool changes. These mechanical attributes reduce set-up variability and support tight process tolerances on production lines.

Practical application guidance for reliable process integration

Equipped with a one-sided chipbreaker and optimised for rostfreie Stähle, the insert performs well in both external and internal turning operations when paired with a suitable holder and stable workholding. Selection of the correct chipbreaker and cutting parameters is important: match the grade and chip control to the component material and the expected stability of the set-up to unlock the insert’s full potential. For mixed-batch production or variable cutting conditions, this insert offers an economical route to consistent component quality and predictable cycle times.

FAQ

What materials is this insert best suited for?
The TCMT16T308 AH6225 insert is specified as a universal grade for machining rostfreie Stähle (stainless steels), delivering a good balance of edge sharpness and stability under varying conditions.

How does the hole and countersink affect clamping?
The cylindrical hole with a single-sided countersink (40°–60°) on the TCMT16T308 promotes secure and repeatable clamping in compatible ISO holders, reducing the risk of rotation or misalignment during turning operations.

Is the insert suitable for both external and internal turning?
Yes, the insert’s geometry and chipbreaker make it suitable for external and internal turning applications when used with an appropriate holder and stable set-up.

What advantages does the AH6225 PVD coating provide?
The AH6225 PVD-coated carbide offers improved wear resistance and a sharper cutting edge compared with uncoated grades, helping to control built-up edge and maintain surface finish during stainless steel turning.

How should the insert be matched to a holder?
Compatibility depends on form, free-cutting angle, tolerance class, fixing method, size and thickness; select an ISO-compatible holder that matches the TCMT16T308 dimensions and clamping style for secure seating.
