TNMG160404 AH6225 Tungaloy turning insert — PVD-coated carbide, 0.4 mm radius

The TNMG160404 AH6225 is an ISO-standard triangular turning insert designed for external and internal turning, engineered for stable cutting performance on stainless steels.

• PVD-coated carbide for increased wear resistance
• Universal grade optimised for stainless steels
• 0.4 mm nose radius for precise contouring
• Double-sided insert with cylindrical hole
• ISO TNMG form, 60° triangle geometry

Consistent tool life through PVD-coated carbide technology

The AH6225 grade combines a PVD-coated surface with a carbide substrate to deliver improved wear resistance and thermal stability in interrupted and continuous cuts. This coating reduces adhesive wear and helps maintain a stable cutting edge, which in turn supports longer unattended runs and fewer indexings. For production environments where repeatability matters, the coated substrate translates into predictable component quality and reduced process variation.

Geometry for repeatable finishes and economical indexing

The triangular 60° form with a 0.4 mm nose radius provides an effective balance between strength and detail, enabling reliable contour turning and shoulder work with good surface quality. The insert is double-sided, offering multiple cutting edges per index to reduce tooling costs per part. The presence of a cylindrical hole allows secure clamping in many standard TNMG-compatible holders; compatibility is determined by form, clearance angle, tolerance class, fixing and size.

System compatibility and recommended application

This insert is part of an ISO turning insert system and is suitable for both external and internal turning operations. Selection of the correct chipbreaker and grade is essential: the AH6225 grade is a universal choice for stainless steels, offering a sharp yet stable edge for medium machining and variable conditions. Typical system setup comprises the insert, a matching external holder or boring bar, a shim/clamp set and replacement screws to secure the insert in the cutting assembly.

Productivity gains and process security for stainless machining

Using the TNMG160404 AH6225 Tungaloy insert supports higher process security through a robust cutting edge and good chip control from the double-sided chipbreaker design. The combination of geometry and grade often yields improved surface finish and consistent edge life, which reduces downtime for rework. For shops aiming to raise throughput while maintaining component quality, this insert offers a pragmatic route to more productive turning cycles.

FAQ

What materials is this insert best suited for?
The TNMG160404 AH6225 insert from Tungaloy (SKU 6796310-Tungaloy) is a universal grade optimised for stainless steels, designed to maintain a sharp, stable edge in varying cutting conditions.

Is the insert indexable and how many cutting edges are available?
This is a double-sided TNMG insert; each side provides multiple edges, enabling economical indexing and extended tool life compared with single-sided designs.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, clearance angle, tolerance class, fixing method, size and thickness; the TNMG160404 conforms to ISO TNMG dimensions for broad holder compatibility.

What benefits does the AH6225 PVD coating provide?
The AH6225 PVD coating improves wear resistance and thermal stability, leading to longer edge life and more consistent part quality during stainless steel machining.

Can this insert be used for both external and internal turning?
Yes, the geometry and ISO form make the insert suitable for both external and internal turning when matched to the appropriate holder or boring bar.

How should the chipbreaker and grade be selected for a given job?
Choose the chipbreaker and grade based on workpiece material, machining type and assembly rigidity; the AH6225 grade is a strong starting point for medium machining of stainless materials.
