CGEU L2020- AH765 turning insert by Tungaloy — ISO rhombic insert for turning

CGEUL2020- AH765 is a compact ISO‑standard indexable insert designed for external and internal turning applications using modern carbide grades.

• ISO‑standard rhombic insert for turning
• PVD‑coated AH765 carbide grade
• Double‑sided chipbreaker, hole with countersink
• 30° clearance angle, 2.38 mm thickness

Reliable cutting performance with modern coating technology

This insert combines a PVD‑coated surface with the AH765 carbide grade to deliver wear resistance and a reliably sharp cutting edge. The PVD layer reduces adhesion and protects the substrate at elevated temperatures, which helps to maintain dimensional consistency over long production runs. Designed to the ISO standard, the insert fits into common external holders and boring bars when form, clearance angle, tolerance class, fastening method, size and thickness are matched, enabling predictable interchangeability and reduced setup time.

Versatile geometry for stable chip control and flexible use

The rhombic geometry with an included angle of 80°, a 30° clearance, and a 2.38 mm plate thickness provides a balance between edge strength and accessibility in confined features. The double‑sided chipbreaker supports effective chip segmentation across a range of cutting parameters, while the cylindrical hole with a double countersink (40°–60°) ensures secure fixation and correct seating in the clamping set. Specified as size L2, the insert is suitable for both fine finishing and medium cutting when paired with an appropriate holder and machine rigidity.

Practical system view and compatibility guidance

An efficient turning setup includes the ISO indexable insert, a matching external holder or boring bar, a shim/clamp set, and replacement screws. Compatibility is determined by a combination of insert form, free clearance angle, tolerance class, fastening arrangement, size and thickness rather than by name alone. Selecting the correct chipbreaker style and the AH765 grade should be based on the workpiece material, the machining operation and the required process stability to achieve consistent surface quality and predictable tool life.

Process benefits and economical operation

Using a wear‑resistant grade such as AH765 with a PVD finish can lead to longer uninterrupted runs and fewer insert changes, improving throughput and reducing downtime. The sharp, stable cutting edge of this insert supports high‑quality finishes and repeatable results, which is especially valuable in batch production or when parts require tight tolerances. The clear technical specification and ISO conformity also simplify tool planning and inventory management for production environments.

FAQ

What materials is this insert suitable for?
The CGEUL2020- AH765 Tungaloy indexable insert is designed for a broad material range when the chipbreaker and cutting data are matched; the PVD‑coated AH765 grade delivers good wear resistance and process security across common steels and alloyed materials.

How does the AH765 grade affect tool life?
The AH765 PVD‑coated carbide provides enhanced wear resistance and a sharp cutting edge, which helps to extend insert life and maintain part quality under stable machining conditions.

Which holders are compatible with this insert?
Compatibility depends on insert form, clearance angle, tolerance class, fastening, size and thickness; the CGEUL2020‑ format fits standard ISO external holders and boring bars that accept L2 rhombic inserts.

Can the insert be used for finishing operations?
Yes — with appropriate cutting data and machine rigidity the rhombic geometry and fine edge of the AH765 grade support high‑quality finishes and repeatable results.

Is the hole and countersink suitable for secure clamping?
The cylindrical hole with a double countersink (40°–60°) gives reliable seating and clamping stability when used with the correct clamp set and screws.
