CFGT R2020- AH922 Turning insert for turning by Tungaloy

The CFGTR2020- AH922 is an ISO‑standard turning insert designed for precision external and internal turning, combining a PVD‑coated carbide grade with a one‑sided chipbreaker and a rhombic R2 geometry for stable cutting.

PVD-coated carbide grade AH922
ISO R2020 rhombic insert, size R2
25° relief angle for stable cutting
Cylindrical hole with 40°–60° countersink

Reliable wear resistance for continuous production

The PVD‑coated carbide substrate offers improved wear resistance and a sharp cutting edge that is maintained over long production runs. The AH922 grade is designed to resist both flank wear and chipping under typical turning conditions, which means fewer indexings and a more predictable tool life. This stability translates directly into higher uptime and lower tooling cost per part, especially where repeatability and consistent surface finish are required.

Predictable chip control and secure clamping

Equipped with a one-sided chipbreaker and a cylindrical hole with a 40°–60° countersink, the insert supports reliable chip formation and evacuation on many holder systems. The rhombic geometry (R2) and ISO form ensure that compatibility with holders is defined by form, clearance angle, tolerance class, clamping method, size and thickness. Where chip shape and evacuation matter, this configuration reduces the risk of built‑up edge and improves process stability.

Versatile application range for turning tasks

Specified for general turning tasks, the indexable insert is suitable for both external and internal turning operations; the combination of a robust grade and precise geometry enables machining of a broad range of materials when the correct grade and chipbreaker are selected. The ISO conformity of the insert simplifies tool selection and replacement procedures in mixed‑brand toolrooms, helping standardise setups and shorten machine downtime during index changes.

System compatibility and setup guidance

The insert forms part of a system comprising an ISO indexable plate, a matching external holder or boring bar, a shim/clamping set and replacement clamp screws. Compatibility depends on holder geometry and clamping details rather than on brand alone; as such, the insert is intended to be used with holders that accept ISO R2020‑type rhombic plates. For complex setups or thin‑walled workpieces, a review of holder rigidity and cutting parameters is recommended to exploit the process reliability of the AH922 grade fully.

FAQ

What materials can be machined with this insert?
The insert is a PVD‑coated carbide grade AH922 designed for a wide range of turning applications; suitability for specific materials should be checked against the grade behaviour and the chosen chipbreaker.

Is the CFGTR2020- AH922 compatible with my existing ISO holders?
Compatibility is determined by holder form, clearance angle, tolerance class, clamping method, size and thickness; the CFGTR2020- AH922 follows ISO R2020‑type geometry and fits holders designed for R2 rhombic plates.

How is chip control achieved with this insert?
Chip control is delivered by the one‑sided chipbreaker and the insert’s rhombic geometry, which together shape and evacuate chips effectively when combined with appropriate cutting parameters.

Can the insert be used for both external and internal turning?
Yes, the insert is intended for both external and internal turning operations when the correct holder and cutting data are selected.

What is the exact product identifier for ordering?
Order using article number 6801685 or SKU 6801685‑Tungaloy for the CFGTR2020‑ AH922 turning insert.
