CFGT L2020- AH880 Turning Insert – ISO turning insert for turning, Tungaloy

The CFGT L2020- AH880 is an ISO-format turning insert engineered for external and internal turning of heat-resistant alloys and other demanding materials.

• PVD-coated cemented carbide grade AH880
• Optimised for heat-resistant alloys
• Rhombic insert, size L2, 25° clearance
• Cylindrical hole with 40°–60° countersink

Durable grade and coating for extended service life

The combination of a PVD-coated surface and cemented carbide substrate in grade AH880 delivers high hot hardness and a stable cutting edge, which reduces flank wear during the machining of temperature-sensitive alloys. The coating acts as a thermal and wear barrier, limiting adhesion and crater wear in high-temperature zones; this translates into fewer insert changes and improved process economy. The ISO-format indexable design also supports straightforward replacement and inventory handling, making the component suitable for production environments where repeatability and uptime are priorities.

Secure clamping and reliable chip control for consistent finishes

The insert’s rhombic shape and central cylindrical hole with a single-sided countersink (40°–60°) enable precise seating and stable clamping in compatible holders, which helps maintain concentricity during turning operations. The specified 25° clearance angle supports good shear formation while reducing rubbing on the flank face. The integrated one-sided chipbreaker is optimised to control swarf flow for many turning setups, improving surface finish and reducing the risk of built-up edge. Together, these design elements lower the likelihood of chatter and contribute to a predictable surface quality on finished components.

System advantages and application-oriented performance

Designed for a complete turning system — insert, matching external holder or boring bar, shim/clamp set and replacement screws — this ISO-format indexable solution allows flexible use across external and internal turning tasks. The geometry is compatible with standard ISO holders when form, clearance angle, tolerance class, fixing method, size and thickness align, enabling rapid tool changes and simplified tooling logistics. Selecting the appropriate chipbreaker and the AH880 grade for workpiece material improves productivity through longer cutting times and steadier tool life, supporting cost-effective batch production and machining of demanding alloys.

FAQ

What materials is this insert suited for?
The CFGT L2020- AH880 turning insert is engineered for heat-resistant alloys and other demanding materials; the AH880 grade and PVD coating support cutting at elevated temperatures.

Which holders are compatible with the insert?
Compatibility depends on holder form, fixation, tolerance class, size and thickness; the ISO-format of the insert ensures interchangeability with standard ISO holders when these parameters match.

How does the hole and countersink design affect clamping?
A cylindrical hole with a single-sided countersink (40°–60°) provides a precise seating surface and uniform clamping force, improving repeatability and reducing the risk of insert movement during turning.

When should the one-sided chipbreaker be selected?
The integrated chipbreaker on this Tungaloy turning insert is suitable for operations where controlled swarf evacuation is required; it is a good choice for many external and internal turning processes to enhance surface finish.

What benefits does the AH880 grade provide?
AH880 is a PVD-coated cemented carbide grade designed for high warm hardness and a stable cutting edge, which increases tool life and maintains consistent performance on heat-resistant and hard-to-machine alloys.
