The combination of PVD-coated carbide AH6225 and a 1.2 mm nose radius delivers a dependable balance of edge sharpness and toughness for medium turning operations on stainless steels; order via Metav Werkzeuge or consult the specialists for application-specific recommendations.

TCMT16T312 AH6225 Tungaloy indexable turning insert (ISO) — PVD-coated carbide, 1.2 mm radius

The TCMT16T312 AH6225 indexable insert is an ISO-format triangular cutting insert designed for external and internal turning of stainless steels in medium-duty and variable operating conditions.

• ISO TCMT triangular insert, 60° geometry
• PVD-coated carbide AH6225 for stainless steels
• 1.2 mm nose radius for reliable surface finish
• Single-sided chipbreaker, with centre hole

Consistent cutting performance for stainless steels

The combination of the AH6225 grade and PVD-coated carbide substrate provides a controlled balance between a sharp cutting edge and wear resistance, optimised for stainless steels under varying cut conditions. The coating reduces built-up edge and enhances thermal stability, which leads to longer tool life and fewer interruptions in production. This insert is suited to medium cutting depths where both edge stability and finish quality matter, offering repeatable results across batch runs and reduced rework rates thanks to its stable cutting behaviour.

Seamless fit in ISO-based turning systems

Designed to the ISO plate family, compatibility with toolholders depends on form, 7° relief angle, tolerance class, fixing method, size and thickness. The triangular 60° geometry and cylindrical hole with single-sided countersink (40°–60°) ensure secure clamping and simple indexability in standard external holders or boring bars. Plate dimensions — including a 16 mm inscribed circle and 3.97 mm thickness — match common ISO carriers, enabling quick changeover and consistent positional accuracy when replacing inserts in production tooling systems.

Predictable chip control and improved surface quality

A single-sided chipbreaker combined with a 1.2 mm nose radius gives stable chip formation and a predictable cutting zone, which supports consistent surface finish and dimensional control when turning stainless steels. The nose radius smooths transitions on radiused profiles while the chipformer helps evacuate chips in medium-duty operations, reducing the risk of workpiece damage. Selecting this insert supports a pragmatic approach to productivity: fewer stoppages for insert changes, more uniform parts off the machine and lower total machining cost per component.

FAQ

Which materials is this insert intended for?
The TCMT16T312 AH6225 insert from Tungaloy is optimised for stainless steels; the PVD-coated carbide AH6225 maintains edge integrity and reduces built-up edge in such materials.

How does the insert attach to the holder and what should be checked?
Compatibility depends on ISO geometry, 7° relief angle, size and thickness; ensure the holder matches the insert’s 16 mm inscribed circle and the cylindrical hole with single-sided countersink for correct clamping.

What surface finish can be expected with a 1.2 mm nose radius?
A 1.2 mm nose radius provides a balance of strength and finish quality suitable for medium machining, improving dimensional stability and producing a consistent surface when used with appropriate feeds and speeds.

Is chip control supported for variable cutting conditions?
Yes — the single-sided chipbreaker is intended to manage chip formation reliably during medium-duty turning and in changing conditions, promoting safe evacuation and reducing recutting.
