CFGT R2020- AH925 — Tungaloy indexable turning insert (PVD-coated carbide, rhombic R2)

The CFGT R2020- AH925 is an ISO‑standard indexable insert for external and internal turning, designed to deliver wear resistance and process security where a sharp cutting edge is required.

PVD-coated carbide AH925 for wear resistance
ISO-standard rhombic R2 insert form
25° clearance angle with cylindrical hole and countersink
2.38 mm thickness for stable clamping

Reliable cutting performance and predictable tool life

The combination of PVD-coated carbide AH925 and a geometry optimised for turning provides process security and consistent results in general turning tasks. The coating improves resistance to abrasive wear while the carbide substrate maintains a sharp cutting edge, reducing the frequency of index changes. For production environments where repeatability is critical, this insert brings measurable efficiency: fewer tool changes and a more consistent surface finish. The product is part of an ISO standard range, which supports rapid replacement and simplifies tool inventory management.

Secure clamping and clear compatibility criteria

Compatibility with the toolholder is determined by insert shape, free angle, tolerance class, fastening, size and thickness; the rhombic R2 form and 25° clearance allow stable seating in many common external holders. The insert features a cylindrical hole with a one-sided countersink (40°–60°) that ensures firm axial and radial location when used with the correct screw and shim. With a 2.38 mm thickness, the insert offers robust clamping contact and improved resistance to chatter compared with thinner grades. The single-sided chip control element—listed as a single-sided chipbreaker—is intended to promote controlled chip formation in routine turning operations.

Practical application guidance and system setup

Typical use covers external and internal turning; choose the chipbreaker and the AH925 grade according to workpiece material, machining strategy and machine stability. The insert is delivered as part of an ISO insert system: the overall setup comprises the indexable insert, an appropriate holder, a supporting shim or clamp and the correct mounting screw. This configuration supports quick insert changes and predictable repeatability, which is particularly valuable in batch production or where multiple tool seats are employed. The specified geometry and coating make the insert suitable where a balance of edge sharpness and wear resistance is required, improving uptime and contributing to a consistent surface finish.
