TNMG160404 AH6225 TNMG turning insert — PVD-coated carbide, 60° triangle (Tungaloy)

The TNMG160404 AH6225 is a triangular ISO turning insert engineered for general external and internal turning, offering a balance of edge sharpness and stability for medium machining of stainless steels

• PVD-coated universal carbide grade AH6225
• Sharp, stable cutting edge for medium cuts
• Double-sided chipbreaker for consistent chips
• ISO 60° triangle with cylindrical hole

Reliable cutting performance for stainless steels

The AH6225 grade combines a PVD-coated surface with a wear-resistant carbide substrate to extend edge life under varying conditions. This universal grade is optimised for stainless steels, giving a sharp yet stable cutting edge that reduces built-up edge formation and improves process stability during medium-duty turning. The coating reduces friction at the tool–workpiece interface, which helps to maintain dimensional accuracy and surface finish over multiple indexed edges, translating to fewer tool changes and higher productivity.

Consistent chip control and machining stability

A double-sided chipbreaker ensures predictable chip formation across a range of cutting parameters, improving swarf evacuation and reducing the risk of surface damage. The 60° triangle geometry provides three usable cutting edges per side and a compact footprint for external and internal operations. The insert’s cylindrical hole and ISO form ensure reliable clamping in standard holders; correct matching of holder form, clearance angle, tolerance class, fastening and thickness is essential for optimal performance and safety in the machining set-up.

Efficient indexable system for day-to-day turning

As an indexable insert, this item supports rapid edge changes and cost-efficient use of the insert body: multiple edges per insert lower cost per cutting edge and limit machine downtime. The grade’s balance between edge sharpness and toughness is particularly suited to varied workshop conditions where material batches and cutting data change frequently. Combined with a compatible external holder and correct chipbreaker selection, the insert contributes to a productive, repeatable turning process with consistent surface quality and tool life stability. Tungaloy’s manufacturing standards support predictable performance across shifts and batches.

FAQ

Is this insert suitable for machining stainless steels?
Yes. The TNMG160404 AH6225 insert uses a PVD-coated carbide grade optimised for stainless steels and provides a balance of sharpness and edge stability suited to medium turning operations.

How many cutting edges are available per insert?
The triangular TNMG geometry offers three edges per side; with the double-sided format this provides multiple indexable edges to reduce cost per cutting edge.

What does the AH6225 designation indicate?
AH6225 denotes a PVD-coated universal grade from Tungaloy that is designed for versatile performance on stainless steels, combining wear resistance with a stable cutting edge.

Does the cylindrical hole affect clamping?
The cylindrical hole ensures reliable seating and clamping in compatible ISO holders; correct holder matching (form, clearance angle and tolerance) is necessary for secure fastening and repeatable results.

Can this insert be used for both external and internal turning?
Yes. The triangular form and standard ISO dimensions make the insert suitable for both external and internal turning, provided a suitable holder or boring bar is used.
