CFGT L2020- AH875 Tungaloy turning insert — PVD-coated carbide, 80° rhombic (25° clearance)

The CFGT L2020- AH875 is an ISO-standard rhombic turning insert designed for external and internal turning of heat‑resistant alloys and other demanding materials.

• ISO rhombic insert, 80° cutting angle
• PVD-coated carbide AH875 for high heat
• 25° clearance angle for secure cutting
• Cylindrical hole with 40°–60° countersink

Reliable cutting performance for heat-resistant alloys

The combination of a PVD-coated surface and the AH875 carbide grade delivers elevated hot hardness and a stable cutting edge when machining nickel‑based alloys and other heat‑resistant materials. The coating reduces adhesion and wear at elevated temperatures, which translates into longer tool life and fewer interruptions in production. For businesses that prioritise consistent results in severe conditions, this insert offers measurable advantages in process stability and component quality, reducing rework and improving throughput.

Fast integration and secure clamping in existing tool systems

As an ISO-standard turning insert, compatibility with existing holders depends on form, clearance, tolerance class, fixation, size and thickness. The cylindrical hole with a single-sided countersink (40°–60°) ensures reliable clamping and alignment in standard clamping systems, while the rhombic form facilitates both external and internal operations. Specifying the correct holder and clamp reduces setup time and vibration, improving surface finish and repeatability across batches. The insert forms part of a simple system: indexable plate, suitable external holder or boring bar, underlay/clamping set and replacement screws.

Optimised chip control and productivity in turning processes

The single-sided chipbreaker and the 80° cutting angle deliver controlled chip formation and stable cutting forces, which supports higher metal removal rates with predictable results. The 25° clearance angle balances edge strength with cutting geometry to maintain a smooth contact zone and minimise rubbing. This configuration is particularly suited to productive turning where surface quality and tool life are critical performance indicators. Adopting this insert can reduce cycle times and tool changes, contributing to lower unit costs and improved shop-floor efficiency.
