TNMG 160412 AH6225 turning insert for ISO-standard turning (Tungaloy)

TNMG 160412 AH6225 is an ISO-form triangular turning insert designed for external and internal turning in production environments, providing a balance between a sharp cutting edge and stable edge life.

• ISO-standard TNMG geometry, 60° triangle
• PVD-coated carbide grade AH6225 for stainless steels
• 1.2 mm corner radius for stable edge formation
• Double-sided insert with cylindrical hole for secure clamping

Consistent performance for stainless-steel turning

The PVD-coated carbide grade AH6225 offers a controlled combination of hardness and toughness that is especially suited to machining stainless steels under varying conditions. As an ISO-standard triangular insert with a 60° included angle, the component provides predictable cutting behaviour and repeatable engagement with the toolholder. The PVD layer improves wear resistance and reduces adhesion tendencies, which translates into longer useful edge life and fewer unexpected tool changes during medium-duty turning operations.

Predictable surface finish and reduced downtime

A 1.2 mm corner radius delivers a robust cutting edge that reduces vibration and helps generate a consistent surface finish on shafts and bores. The double-sided design effectively doubles the available cutting edges, while the cylindrical hole ensures secure clamping in compatible holders, cutting setup time and minimising the risk of movement under load. This indexable solution therefore supports higher machine uptime and more predictable cycle times, making it suitable for batch production and mixed-operation workshops.

Easy integration into existing turning systems

Compatibility with ISO holders is determined by geometry, relief angle and tolerance class; the insert’s 0° relief and standard TNMG form allow straightforward replacement in common external and internal toolholders. The insert is designed to work with appropriate chipbreakers and holders for optimal chip control, and selecting the correct chipbreaker and cutting data will deliver the best balance between material removal rate and tool life. As part of an indexable system, this insert simplifies inventory management and reduces total tooling cost per component.

FAQ

What materials is this insert designed for?
The TNMG 160412 AH6225 turning insert from Tungaloy (SKU 6947355-Tungaloy) is primarily intended for machining stainless steels and is optimised for medium cutting conditions.

Can the insert be used on internal bores as well as external shafts?
Yes, the TNMG160412 geometry and its 1.2 mm corner radius make the insert suitable for both external and internal turning when paired with the correct holder and chipbreaker.

How does the AH6225 grade improve tool life?
The AH6225 PVD-coated carbide combines a hard coating with a stable substrate, reducing wear and adhesion on stainless steels and thus prolonging the effective cutting edge life of the insert.

Is the insert compatible with standard ISO toolholders?
Compatibility depends on form, relief angle, tolerance class and thickness; the ISO designation TNMG160412 is intended for use with matching ISO holders and clamps in common turning tool systems.

What are the main benefits of the double-sided design?
A double-sided triangular insert provides multiple usable edges, improving cost efficiency per edge and offering quicker edge changes compared with single-edge solutions.
