CFGT L2020- AH879 — ISO rhombic turning insert, 80° included angle, by Tungaloy

The CFGT L2020- AH879 is an ISO-format, rhombic turning insert designed for external and internal turning of demanding materials, optimised for heat-resistant alloys and high-temperature stability.

• PVD-coated carbide grade AH879
• ISO rhombic insert, 80° included angle
• 25° clearance angle for stable cutting
• Cylindrical hole + single-sided countersink

Higher cutting stability and extended tool life for demanding alloys

The insert delivers consistent edge stability through its PVD-coated carbide grade AH879, a combination engineered for elevated hot hardness and wear resistance when machining heat-resistant alloys. This results in longer intervals between insert changes and more predictable tool life, which translates directly into lower machine downtime and reduced cost per component. The robust edge geometry supports interrupted cuts and high-temperature contact zones, maintaining dimensional accuracy over longer runs.

Seamless integration into ISO turning systems for quick setup

Compliance with ISO dimensions and the rhombic form ensure straightforward interchangeability with standard ISO holders and boring bars. The 80° included angle and 25° clearance angle promote secure seating and repeatable cutting geometry, while the cylindrical hole with a single-sided countersink (40°–60°) simplifies clamping and torque transfer. The insert forms part of a complete system—insert, appropriate external holder or boring bar, shim/clamp set and replacement screws—allowing for predictable assembly and rapid tool changes on the shop floor.

Efficient chip control and process reliability for everyday production

Featuring a one-sided chipbreaker, the design channels chips away from the cutting zone to reduce re-cutting and improve surface finish, particularly in turning operations. The optimized chip control lowers cycle times through higher stable cutting parameters and reduces the need for secondary cleaning operations. Selecting the correct chipbreaker and grade for the workpiece material ensures reproducible results, increased throughput and greater overall process reliability on both small batch and serial production runs.

FAQ

What materials is this insert suited for?
The CFGT L2020- AH879 insert is formulated for heat-resistant alloys and other demanding materials; the AH879 grade provides elevated hot hardness and wear resistance for such applications.

How does the hole and countersink affect mounting?
The cylindrical hole with a single-sided countersink (40°–60°) on the insert ensures secure clamping and reliable torque transmission when mounted in compatible ISO holders and reduces the risk of movement under heavy cuts.

Is the chip control suitable for high-feed turning?
Yes, the one-sided chipbreaker on this rhombic insert supports efficient chip evacuation and improved surface finish, enabling higher stable feeds in many turning operations.

Can the insert be used for internal boring as well as external turning?
The ISO rhombic geometry and standardised dimensions make the insert compatible with appropriate boring bars and external holders, allowing use in both internal and external turning applications where the form and size match.
