CNMG 160616 AH6235 – ISO turning insert (rhombic, 80°) by Tungaloy

CNMG 160616 AH6235 is an ISO-standard indexable insert designed for precision external and internal turning, optimised for stainless steels and interrupted cutting conditions.

PVD-coated carbide AH6235 for tough materials
80° rhombic geometry for stable cutting
Double-sided chipbreaker for versatile machining
Cylindrical hole and 6.35 mm thickness for secure clamping

Enhanced performance for stainless steel and demanding cuts

The AH6235 grade is a PVD-coated cemented carbide designed to combine toughness with wear resistance, making it well suited to stainless steel and operations prone to chipping. The harder-coated surface gives improved flank and crater wear resistance, while the substrate toughness helps to absorb shocks during interrupted cuts. This mix of properties translates into fewer edge failures and more predictable tool life, which supports consistent cycle times and reduced scrap rates in production environments.

Secure clamping and geometric advantages for process stability

The 80° rhombic geometry with a 1.6 mm corner radius and 6.35 mm plate thickness provides a stable cutting configuration that resists deflection under radial loads. The insert’s cylindrical hole and standard ISO form allow compatibility with a wide range of external holders and boring bars; compatibility is determined by form, clearance angle, tolerance class, mounting and size. The double-sided chipbreaker offers economical indexing and dependable chip control across a range of feed rates, supporting both finishing and medium-turning operations.

Reduced downtime through robust edge control and predictable behaviour

Thanks to the AH6235 substrate and PVD finish, the insert exhibits improved resistance to notch wear and thermal softening in the contact zone. The enhanced mechanical integrity reduces unexpected edge breakouts during transient conditions, leading to fewer unplanned tool changes. For workshops seeking a balance between edge life and fracture resistance, this insert provides a pragmatic route to higher uptime and more stable surface finishes without complex process tunes.

System-level thinking for reliable integration

These ISO indexable plates are best used as part of a complete system: the insert, a matched external holder or boring bar, a suitable backing/clamping kit and replacement screws. Selecting the appropriate chipbreaker and grade according to workpiece material and cutting parameters ensures repeatable results. For mixed batches or interrupted surfaces, the tougher grade reduces the need for frequent tool trials, enabling faster production start-ups and consistent part quality.

FAQ

Is this insert suitable for stainless steel machining?
The AH6235 grade was developed for tougher applications and is suitable for stainless steel work, offering improved resistance to chipping and notch wear during interrupted cuts.

Can the CNMG 160616 be used for both external and internal turning?
Yes, the ISO‑standard CNMG 160616 geometry is intended for both external and internal turning when paired with a compatible holder or boring bar.

How does the PVD coating affect tool life?
The PVD coating on the AH6235 grade increases surface hardness and reduces adhesive wear, which enhances flank and crater resistance and contributes to more consistent tool life in demanding conditions.

What is the benefit of the double-sided chipbreaker?
A double-sided chipbreaker allows economical indexing and provides reliable chip control across different feeds, which simplifies inventory and increases uptime.

Which holder characteristics must be checked for compatibility?
Compatibility depends on form, clearance angle, tolerance class, mounting arrangement, size and thickness; ensure the holder matches the ISO CNMG form and the insert’s dimensions.
