CNMG 120412 AH6235 Tungaloy turning insert – PVD-coated carbide, 1.2 mm radius

CNMG 120412 AH6235 is an ISO‑standard rhombic turning insert designed for external and internal turning, especially where stainless steels and interrupted cuts demand a tougher grade.

• PVD-coated carbide grade AH6235
• Optimised for stainless steels and interrupted cuts
• Rhombic 80° form, 1.2 mm corner radius
• Double-sided insert with cylindrical mounting hole

Higher process reliability in demanding stainless-steel turning

The combination of a PVD-coated surface and the AH6235 grade results in a tougher cutting edge that resists edge breakdown during interrupted or unstable cuts. With a 1.2 mm corner radius, the geometry increases cutting stability while maintaining a good surface finish; this translates into fewer tool changes and more predictable cycle times on stainless steels. Where coolant, variable chip thickness or workhardening are factors, this configuration helps keep machining within target tolerances.

Easy integration into standard ISO holder systems for rapid exchange

Designed to the ISO CNMG format, the rhombic 80° plate with a cylindrical hole and a 0° relief angle matches conventional external holders and boring bars. Compatibility is determined by insert form, relief angle, tolerance class, fastening, size and thickness; the double-sided nature and a plate thickness of 4.76 mm permit economical indexing. This standardisation reduces setup complexity on the shop floor and enables quick, secure clamping for consistent repeatability.

Extended tool life and stable chip control for productive turning

The double-sided chipbreaker and PVD finish improve chip control and wear resistance, reducing unplanned downtime and contributing to overall cost-efficiency. In applications with increased breakout risk or interrupted cuts, the tougher grade offers enhanced edge retention and fewer fracture-related rejects. For workshops seeking reliable throughput, this insert supports a balance of process stability and extended service life, while retaining the operational simplicity of indexable tooling.

FAQ

Which materials is this insert intended for?
The CNMG120412 AH6235 Tungaloy insert is optimised for stainless steels and performs well in interrupted cuts and applications with elevated breakout risk.

Can the insert cope with interrupted turning and variable cutting conditions?
Yes; the tougher AH6235 grade and the double‑sided chipbreaker provide improved edge retention and chip control under interrupted or unstable cutting conditions.

What determines compatibility with a toolholder?
Compatibility depends on insert form, relief angle, tolerance class, fastening method, size and thickness; the CNMG geometry and 4.76 mm thickness fit standard CNMG holders.

Is the insert indexable and reversible?
Yes; the plate is double-sided and indexable, allowing multiple cutting edges per insert and economical reuse.

How does the AH6235 grade compare with standard PVD grades?
AH6235 is a tougher PVD-coated carbide formulated to resist edge chipping in stainless steels and applications with frequent interruptions, offering stable performance and longer in-process life compared with more wear-focused grades.
