CNMG 120408 AH110 Tungaloy indexable insert — Turning insert for ISO turning applications, PVD-coated carbide

A CNMG120408 AH110 indexable insert designed for ISO‑compliant external and internal turning, offering a balanced combination of sharp cutting edge and resistant coating for productive metal‑cutting operations

• ISO-compatible rhombic insert with 80° geometry
• PVD-coated cemented carbide, grade AH110
• Double-sided chipbreaker for stable cutting
• Cylindrical hole for secure clamping

Consistent component quality through a sharp, wear-resistant cutting edge

The combination of a PVD-coated surface and cemented carbide substrate in this grade delivers a hard, wear‑resistant barrier against abrasive wear and built‑up edge. The result is a more consistent surface finish on workpieces and fewer unscheduled tool changes, which translates into improved productivity for serial turning operations. The AH110 grade is optimised for applications demanding both a keen cutting edge and reliable process stability, reducing the likelihood of premature flank wear or chipping during medium‑to‑general turning tasks.

Stable chip control and process reliability for safer machining

A double-sided chipbreaker is provided to promote controlled chip formation across a range of cutting conditions, improving evacuations and lowering the chance of entangling chips. This contributes directly to enhanced process reliability by enabling longer uninterrupted runs and reduced machine downtime. Selection of the appropriate chipbreaker and grade should be matched to workpiece material and machining stability to maximise cutting performance and part repeatability.

ISO compatibility and geometry that supports versatile turning

The rhombic form with an included angle of 80° and a 0° clearance geometry offers broad applicability in both external and internal turning, while the 0.8 mm corner radius balances edge strength with achievable surface finish. Plate thickness of 4.76 mm and the cylindrical hole ensure secure clamping in ISO‑standard holders, simplifying insert changeovers and tool inventory management. The ISO designation and dimensional conformity make this insert straightforward to integrate into existing tooling systems for predictable set‑up times.

FAQ

What materials is this insert suitable for?
The CNMG120408 AH110 insert from Tungaloy is a wear‑resistant PVD‑coated cemented carbide grade intended for a wide range of steels and general turning applications; choose the chipbreaker and cutting data according to the specific workpiece material.

Can the insert be used for both external and internal turning?
Yes, the rhombic CNMG geometry and 80° included angle make the insert suitable for both external and internal turning when mounted in a compatible ISO holder.

How does the 0.8 mm corner radius affect performance?
A 0.8 mm corner radius increases edge strength and resistance to chipping while offering a reasonable surface finish; it is a compromise between robustness and achievable surface quality.

Is the insert reversible or single‑use?
The plate is double‑sided with a chipbreaker on both faces, allowing indexation to a fresh cutting edge when one face is worn, which extends tool life and reduces tooling costs.

What is the hole style and how does it influence clamping?
The insert features a cylindrical hole which enables stable and repeatable clamping in standard ISO toolholders, contributing to predictable set‑ups and secure fixation during heavy cuts.
