CFGT L2020- AH867 ISO turning insert by Tungaloy — PVD-coated carbide, rhombic L2 for demanding alloys

The CFGT L2020- AH867 is an ISO-standard rhombic indexable turning insert designed for external and internal turning of heat-resistant alloys and other demanding materials, offering robust edge stability and predictable tool life.

• PVD-coated carbide AH867 for high hot hardness
• ISO rhombic L2 insert, 80° included angle
• 25° clearance angle for predictable cutting geometry
• Single-sided chipbreaker for controlled chip formation

Maximum productivity in high-temperature turning

The PVD-coated AH867 grade is formulated for heat-resistant alloys and demanding workpiece materials, delivering a combination of high hot hardness and edge stability that extends tool life under thermal load. This turning grade reduces flank wear and enables longer uninterrupted cycles, which improves throughput and lowers overall machining costs. The coating supports higher cutting speeds and consistent performance, so machining windows remain stable even as temperature rises.

Precise fit and stable fixation for repeatable results

Compatibility with the toolholder is ensured by matching the insert’s shape, 25° clearance, tolerance class, fastening style, size and thickness. The ISO-standard geometry and rhombic L2 outline guarantee a defined seating and repeatable positioning, which reduces vibration and improves surface finish. A correct fit translates into fewer reworks and steady process capability, especially important for serial production where repeatability determines part quality and uptime.

Controlled chip formation and reliable clamping

The single-sided chipbreaker is optimised for chip control on tough materials, producing short, consistent chips that are easier to evacuate and handle. The insert’s cylindrical hole with a 40°–60° countersink ensures secure clamping and correct axial positioning in the seat. Together these features protect the cutting edge, reduce the risk of workpiece damage and simplify swarf management, contributing to safer and more efficient workshop processes.

Seamless integration into a turning system

This insert is part of a standard turning system: ISO insert, matching external holder or boring bar, shim/clamping set and spare screws. Typical applications include external and internal turning where high thermal resistance and edge stability are required. Selecting the right chipbreaker and grade in relation to workpiece material and machining conditions yields the greatest benefits: improved surface quality, longer tool life and fewer tool changes during a shift. If the machining task is unclear, technical consultation is recommended to select the optimal combination.
