CNMG120408 AH6235 Tungaloy turning insert — PVD-coated carbide, 80° rhombic for turning

CNMG120408 AH6235 Tungaloy turning insert is an ISO‑standard rhombic insert designed for external and internal turning applications and for operations with elevated breakout risk

• CNMG120408 ISO rhombic insert, 80° geometry
• PVD-coated carbide AH6235 for stainless steel
• Double-sided chipbreaker for interrupted cuts
• Cylindrical central hole for secure clamping

High process reliability through robust grade and coating

The combination of a PVD-coated surface and a tough carbide substrate gives the insert enhanced edge strength and wear resistance. This construction reduces flank wear and supports longer tool life under intermittent loading, which translates into fewer tool changes and improved machine utilisation. The AH6235 grade is developed specifically for demanding conditions, offering a balance between toughness and wear resistance that benefits batch production and mixed‑material runs.

Stable cutting in interrupted cuts and stainless steel

A double-sided chipbreaker paired with an 80° geometry ensures controlled chip formation and helps prevent edge chipping during interrupted cuts. The insert is particularly suited for machining stainless steel, where toughness and work hardening can challenge conventional grades. The modest clearance angle of 0° increases radial support at the cutting edge, improving stability when facing heavy engagement or variable cutting conditions.

ISO compatibility and secure clamping for efficient workshop use

The insert conforms to ISO standards for form and size, facilitating replacement and inventory management across compatible holders. The cylindrical central hole and standard thickness (4.76 mm) ensure consistent seating and clamping with conventional insert systems; compatibility depends on holder form, tolerance class, fastening type, size and thickness. Using standardised components simplifies tool set‑up, reduces downtime and supports predictable process planning.

FAQ

Is this insert suitable for stainless steel?
Yes. The CNMG120408 AH6235 turning insert from Tungaloy is specified for stainless steel applications, offering enhanced toughness and a PVD surface to resist built‑up edge.

Can the insert be used for internal turning as well as external turning?
Yes. The ISO rhombic form and 80° geometry make the insert suitable for both external and internal turning when paired with an appropriate holder.

How does the double‑sided chipbreaker affect tool life?
The double‑sided chipbreaker on the CNMG120408 AH6235 improves chip control and reduces the risk of edge chipping during interrupted cuts, which supports more consistent tool life and fewer indexings.

What ensures proper clamping of this insert?
A cylindrical central hole and standard thickness (4.76 mm) provide reliable seating; correct compatibility depends on the holder’s form, tolerance class, fastening and size.

Is this an ISO‑standard insert for easy replacement?
Yes. The insert conforms to ISO dimensions and form, enabling straightforward replacement and inventory management across compatible tool systems.
