TNMG160412 AH6225 – ISO turning insert by Tungaloy for medium stainless steel applications

TNMG160412 AH6225 is an ISO‑standard turning insert designed for external and internal turning in a wide range of stainless steels and similar materials

• ISO‑standard 60° triangular geometry
• PVD‑coated carbide AH6225 for stainless steel
• Double‑sided insert with cylindrical hole
• 1.2 mm corner radius for durable cutting edge

Consistent medium‑duty performance for stainless steel turning

The TNMG160412 AH6225 is specified with a PVD‑coated carbide grade (AH6225) that balances sharpness and edge stability for common stainless steel turning tasks. The PVD coating improves wear resistance and reduces built‑up edge, which helps to maintain surface finish and dimensional consistency during medium cutting conditions. In practice this means fewer interruptions for insert indexing and a more stable process window when facing variable batch material or interrupted cuts.

ISO compatibility and secure clamping for reliable indexing

Supplied as an ISO‑standard triangular insert, the component is compatible with holders that match the insert’s form, relief angle, tolerance class, clamping and size. The insert is made with a cylindrical hole, enabling positive, repeatable clamping in matched toolholders and reducing micro‑movement under load. The clear definition of size (16 mm), thickness (4.76 mm) and hole style simplifies selection of matching carriers and underlay plates for predictable tool life and process repeatability.

Fewer tool changes, more uptime

A double‑sided design combined with the 60° geometry and 1.2 mm corner radius provides a robust cutting edge for medium turning operations while allowing two usable edges per side. The plate’s thickness and geometry contribute to consistent chip control, improved edge life and fewer tool changes over a production shift. This supports a productive machining cycle and lowers the frequency of secondary interventions, which is particularly valuable in mixed‑batch or small‑series environments.

FAQ

What materials is the TNMG160412 AH6225 suitable for?
The TNMG160412 AH6225 Tungaloy insert is designed primarily for stainless steel machining; the AH6225 PVD‑coated carbide grade delivers a good balance of sharpness and wear resistance for medium turning operations.

Is the insert indexable and reversible?
Yes, the TNMG160412 AH6225 is double‑sided and indexable, providing multiple cutting edges to extend in‑service life and reduce the frequency of insert changes.

How should the holder be matched to this insert?
Matching a holder requires attention to the insert’s form, relief angle (0°), tolerance class, clamping method and dimensions; the TNMG160412 AH6225 uses a cylindrical hole for secure clamping in compatible holders.

What are the key dimensions and geometry of this plate?
The insert has a 60° included angle, a 1.2 mm corner radius and a thickness of 4.76 mm, corresponding to the ISO‑designation TNMG160412.

Can this insert cope with interrupted cuts and varying conditions?
The AH6225 PVD grade and the insert’s robust geometry are optimised for variable cutting conditions and provide a balance between edge sharpness and stability, making it suitable for many interrupted or mixed‑condition turning tasks.
