CNMG120416 AH6235 — CNMG turning insert, PVD-coated carbide, 1.6 mm by Tungaloy

CNMG120416 AH6235 is an ISO-conformant indexable insert designed for external and internal turning, optimised for stainless steels and interrupted cuts

• PVD-coated carbide grade AH6235
• Designed for stainless steel machining
• Double-sided chipbreaker for consistent chips
• 1.6 mm nose radius for stable finishes

Greater process reliability for stainless steel turning

The PVD-coated AH6235 grade is engineered for tougher applications and provides a balanced combination of toughness and wear resistance. On materials prone to work-hardening and built-up edge, such as stainless steels, the coating improves thermal resistance and adhesion control, while the carbide substrate delivers the mechanical strength required under interrupted cutting conditions. This results in superior chip control, reduced risk of edge breakout and fewer unplanned tool changes — a clear benefit for production environments where cycle time and consistent part quality are critical.

Geometry and edge preparation for repeatable surface quality

The insert’s 1.6 mm nose radius and rhombic CNMG geometry deliver a robust cutting edge capable of producing repeatable surface finishes with controlled cutting forces. The geometry, combined with the double-sided chipbreaker, allows two usable edges per index, improving tool utilisation and lowering tooling cost per part. The 80° approach angle and the ISO designation ensure predictable cutting behaviour and straightforward integration into standard turning holders, supporting accurate, repeatable results in both roughing and finishing passes.

System compatibility that reduces setup complexity

Compatibility with toolholders is determined by form, clearance, tolerance class, attachment, size and thickness; the ISO-Drehwendeschneidplatten system concept streamlines selection across inserts, external holders and clamping sets. The insert’s cylindrical hole and standard thickness simplify mounting and spare-part management, while the model-series approach supports consistent inventory and faster changeovers. By viewing the insert as part of a system — insert, holder, underlay/clamping set and replacement screws — shops achieve better process stability and fewer dimension-related errors during setup.

Operational efficiency and measurable savings

Using a grade tailored to the material and an effective chipbreaker leads to longer tool life and fewer interruptions for regrinding or replacement, which improves overall machine uptime. For production-focused shops, the result is higher productivity and a lower cost per component thanks to improved edge life and predictable performance. The combination of PVD-coated surface treatment and robust carbide core supports demanding stainless-steel applications while reducing scrap and rework — delivering tangible economic benefits over conventional grades.

FAQ

Is this insert suitable for machining stainless steel?
Yes. The CNMG120416 AH6235 insert uses a PVD-coated carbide grade optimised for stainless steels, offering improved thermal resistance and chip control for such materials.

Can the insert be used for both external and internal turning?
Yes. The CNMG120416 geometry and ISO conformity make the insert suitable for external and internal turning when mounted in the appropriate holder.

What does the AH6235 grade offer compared with standard grades?
The AH6235 grade provides increased toughness and a PVD surface that enhances wear resistance and reduces the risk of edge breakout in interrupted cuts.

How is the insert fixed to the holder?
The insert features a cylindrical hole for standard clamping; compatibility depends on holder form, tolerance class, attachment method, size and thickness.

How many cutting edges are available per insert?
The rhombic CNMG shape with a double-sided chipbreaker provides multiple usable edges, improving tool economy and lowering cost per cutting edge.
