CGEU L2020- AH764 Tungaloy turning insert — PVD-coated carbide, rhombic L2, 30° relief

The CGEU L2020- AH764 is an ISO-standard rhombic indexable insert designed for diverse external and internal turning applications where a sharp cutting edge and consistent process security are required.

• ISO-standard rhombic L2 geometry
• PVD-coated carbide AH764 for edge stability
• 30° relief for versatile turning
• Cylindrical hole with double countersink

Consistent edge life and predictable results for series production

The combination of a PVD-coated carbide substrate and the AH764 grade offers a balance between wear resistance and fracture toughness, providing a sharp cutting edge that withstands intermittent loads. As an ISO-standard indexable insert, this plate is intended for reproducible tool setups and simplified tool change procedures, which reduces machine downtime and supports steady cycle times. The 30° relief contributes to versatile engagement angles, enabling effective chip formation in a wide range of turning tasks and helping maintain surface finish quality throughout longer production runs.

Easy integration into standard tool systems for fast setup

Compatibility with holders depends on form, relief angle, tolerance class, fastening method, size and thickness, and this insert follows ISO conventions to ease selection. The rhombic L2 form combined with a cylindrical hole and double countersink (40°–60°) secures reliable clamping and repeatable seating in suitable external holders or boring bars. Such mechanical consistency minimises wobble and ensures the insert remains in the correct cutting position, supporting reproducible part geometry and reducing rework rates during serial machining.

Grade and chip control engineered for secure turning operations

The AH764 carbide grade is engineered for situations where a sharp cutting edge and process reliability are essential. The plate’s double-sided chipbreaker geometry supports controlled chip flow, improving evacuation in both external and internal turning and lowering the risk of chip-related workpiece damage. Where stable cutting edges and predictable tool life matter, this insert’s specifications favour steady material removal and help maintain surface integrity, making it suitable for general turning in industrial production where repeatability is valued.

FAQ

What materials is this insert suited for? This insert in AH764 grade is intended for general turning where a sharp cutting edge and reliable performance are required; suitability for specific steels or alloys should be confirmed against machining parameters.

How does the insert secure in the toolholder? The rhombic L2 form with a cylindrical hole and double countersink provides mechanical clamping that matches ISO-standard holders when the holder form, tolerance and fastening method correspond to the insert geometry.

Can the insert be used for internal turning or boring operations? Yes, the plate’s geometry and double-sided chipbreaker enable its use in both external and internal turning, provided the chosen holder and setup match the insert’s size and clearance requirements.

What advantage does the PVD coating deliver? The PVD-coated carbide surface increases wear resistance while preserving a precise cutting edge, which supports consistent surface finish and extended life under many turning conditions.
