CNMG 160616 AH6225 – Indexable turning insert, PVD-coated, for turning (Tungaloy)

CNMG160616 AH6225 is an ISO‑standard rhombic indexable insert designed for external and internal turning, optimised for rostfreier Stahl and general turning tasks

• PVD-coated cemented carbide AH6225
• Optimised for rostfreier Stahl turning
• 80° rhombic geometry with 1.6 mm radius
• Double-sided chipbreaker, cylindrical hole

Reliable performance for rostfreier Stahl and mixed conditions

The CNMG160616 AH6225 insert combines a PVD coating with a tough cemented carbide substrate to deliver consistent cutting under variable conditions. The AH6225 grade is engineered as a universal option for processing rostfreier Stahl, offering a balance between edge sharpness and wear resistance. This translates into fewer tool changes and more predictable cycle times in batch production. Explaining briefly: the PVD layer reduces friction and adhesion tendencies while the carbide core sustains the cutting edge at moderate cutting speeds, resulting in improved process stability.

Stable cutting edge and controlled chip formation

A sharp but resilient cutting edge is central to achieving good surface finish and repeatable tool life. The insert’s double-sided chipbreaker promotes controlled chip segmentation for a wide range of feeds, reducing the risk of built-up edge on difficult-to-machine alloys. The 1.6 mm corner radius supports feed robustness and distributes cutting forces across a larger area, lowering the incidence of premature chipping. As a result, component quality becomes more consistent and post-process rework is minimised, which benefits both small-series and high-volume production.

Designed for fast integration and low setup time

Compatibility with standard ISO holders is determined by geometry, relief angle and thickness; this insert’s 80° geometry, cylindrical hole and 6.35 mm thickness make it straightforward to mount in commonly used external holders and boring bars. The rhombic shape allows for multiple indexing positions, extending service life per insert and reducing inventory turnover. Clear mechanical fit and standardised dimensions support quick changeovers and minimise machine downtime, thereby improving overall shop-floor productivity.

FAQ

What materials is this insert best suited for?
The CNMG160616 AH6225 insert is optimised for rostfreier Stahl and performs well across a broad range of steels and mixed materials when the correct chipbreaker and machining parameters are selected.

How does the AH6225 grade improve tool life?
AH6225 combines a PVD coating with a durable cemented carbide substrate to reduce adhesion and wear, delivering a stable cutting edge and longer service intervals under varying turning conditions.

Can the insert be indexed to use multiple cutting edges?
Yes, the rhombic geometry and double‑sided design allow multiple indexings, which extends the usable life per insert and reduces tooling costs per part.

Is this insert compatible with standard ISO CNMG holders?
The insert follows the ISO CNMG160616 designation and is compatible with holders that match the form, relief angle, tolerance class, fastening and thickness specifications.

What are the benefits of the cylindrical hole and 6.35 mm thickness?
The cylindrical hole and 6.35 mm thickness provide secure clamping and robust support in the pocket, improving stability during interrupted cuts and heavy roughing passes.
