High-performance wear behaviour for stainless-steel turning

The combination of a PVD-coated carbide substrate and the AH6225 grade produces a cutting edge that balances sharpness with edge stability. This results in longer tool life and consistent cutting forces across varying cutting conditions, reducing unscheduled tool changes and supporting higher uptime. For production environments machining stainless steels, the durable coating improves resistance to built-up edge and abrasion, while the sharp geometry aids chip formation and surface integrity.

Predictable geometry and secure clamping for repeatable results

Designed as an ISO turning insert with a 60° included angle and triangular form, the insert fits a wide range of conventional holders. The cylindrical hole and matching clamp system provide secure fixation; the 0° relief geometry suits neutral cutting strategies and helps maintain steady chip flow. A 0.4 mm corner radius is a practical compromise for many turning tasks, offering improved tool strength over finer radii while still enabling refined surface finish. The double-sided chipbreaker gives two usable edges, increasing cost-efficiency per insert.

Practical system benefits and process reliability

Integration into the typical insert system—insert, external holder or boring bar, clamp and replacement screws—keeps tooling straightforward and serviceable. The grade and chipbreaker selection support adaptable machining: choose the chip control and stability level to match material, depth of cut and feed. Backed by Tungaloy manufacturing standards, the insert contributes to process security and reproducible surface quality, helping to lower scrap rates and improve overall throughput.

FAQ

What materials is this insert suited for?
The TNMG160404 AH6225 insert is optimised for machining stainless steels, with the AH6225 grade providing a compromise between sharpness and edge strength for medium cutting conditions.

How does the chipbreaker affect performance?
The double-sided chipbreaker on the insert supports consistent chip control and allows two indexable edges per side, improving economy and helping to maintain stable cutting during external and internal turning.

Can this insert be used in standard ISO holders?
Yes, the insert follows ISO turning insert geometry and fits compatible holders; correct matching depends on holder form, tolerance class, fastening and insert thickness.

What does the 0.4 mm corner radius mean for surface finish?
A 0.4 mm corner radius provides a balance between edge strength and finish capability: it gives better edge stability than finer radii while still enabling a smooth surface with appropriate feeds.

Is the insert reversible or indexable?
The triangular shape and double-sided chipbreaker allow multiple indexings; the secure cylindrical hole fixing ensures repeatable seating for each index.
