TNMG160408 AH6225 Tungaloy indexable insert — ISO triangular insert for turning, 60°

TNMG160408 AH6225 is an ISO‑standard triangular indexable insert engineered for external and internal turning tasks, optimised for stainless steels and variable workshop conditions

• PVD‑coated carbide grade AH6225
• Universal for stainless steels
• Sharp yet stable cutting edge
• ISO triangular, 0.8 mm nose radius

Longer tool life with dependable edge geometry

The PVD‑coated carbide in grade AH6225 combines a sharp cutting edge with enhanced edge stability, which translates into longer tool life when machining demanding materials such as stainless steels. The coating reduces adhesion and softening at elevated temperatures, so the tool maintains form under intermittent cuts and varying feed rates. For mid‑range cutting conditions the result is a consistent surface finish and reduced index changes, helping to lower overall machining costs through fewer interruptions and predictable tool consumption.

Faster set‑up and reliable interchangeability on ISO systems

Designed as an ISO‑standard triangular insert, the TNMG160408 ensures compatibility with a wide range of external holders and boring bars; form, free angle, tolerance class, fastening style and thickness determine actual fit. The triangular shape and cylindrical hole enable secure clamping and straightforward orientation, while the 60° geometry provides versatility for both finish and semi‑rough turning. Specified dimensions such as the 16 mm size and 4.76 mm thickness make tool selection and inventory control simpler in CNC environments, reducing machine set‑up time and supporting predictable production flows.

Optimised cutting performance through geometry and chip control

The insert’s 0.8 mm nose radius balances tool strength with achievable surface quality, making it suitable for medium machining operations where form and tolerance matter. A double‑sided chipbreaker supports efficient chip formation across a range of feeds and depths of cut; selecting the appropriate breaker and machining parameters minimises vibration and prevents poor chip evacuation. The PVD‑coated carbide substrate resists wear and edge chipping, resulting in repeatable performance across batches and easier process stabilisation in mixed‑material production.

FAQ

What materials is this insert suited to machine?
The TNMG160408 AH6225 insert is specified as a universal grade for stainless steels and performs well under changing conditions where a sharp, stable edge is required.

How does the AH6225 grade affect process stability?
AH6225 is a PVD‑coated carbide grade designed to maintain a stable cutting edge at moderate cutting parameters, providing reliable surface finish and predictable tool life for turning operations.

What does the designation 160408 indicate?
The code relates to the ISO geometry: a 16 mm size, a 0.8 mm nose radius and the insert form coded in the ISO series — matching holder and clamp requirements for straightforward interchange.

Can the insert be used for both external and internal turning?
Yes, the triangular form and the cylindrical hole enable secure clamping in suitable external holders and boring bars, making the insert usable for both external and internal turning tasks.

Which chipbreaker should be selected for mixed production?
The double‑sided chipbreaker offers flexibility; choosing the side and adapting feed and depth of cut to material and rigidity will deliver improved chip control and reduced risk of built‑up edge.
