CFGT L2020- AH874 Turning insert (indexable) by Tungaloy — PVD-coated carbide, 80° rhombic

CFGTL2020- AH874 Tungaloy indexable insert engineered for ISO-standard turning applications, offering a high-hot-hardness grade suited to demanding materials.

• PVD-coated carbide AH874 for high hot hardness
• ISO L2020- rhombic insert with 80° cutting angle
• Single-sided chipbreaker with cylindrical hole
• Compatibility depends on holder form and tolerance

Consistent productivity with a high-temperature carbide grade

The insert is made from carbide with a PVD coating in grade AH874, designed specifically for machining heat-resistant alloys and other demanding materials. That composition provides a stable cutting edge and elevated resistance to thermal softening, which translates into longer tool life and fewer indexings. For production environments this means fewer interruptions and more consistent cycle times, while the PVD layer improves wear resistance without compromising edge sharpness.

ISO conformity and assured mounting for predictable results

Designed as an ISO-standard plate in the L2020- family, the rhombic shape with an 80° included angle and 25° clearance ensures predictable geometry when used with compatible turning holders. The insert is supplied with a cylindrical hole and a one-sided countersink (40°–60°) for secure clamping; compatibility is influenced by holder form, free angle, tolerance class, fastening, size and thickness. The combination of standardised form and defined seating means repeatable positioning and consistent cutting forces, which supports reliable surface finishes and tool-change routines.

Practical chip control and application guidance for turning tasks

A single-sided chipbreaker profile promotes controlled chip formation for many turning operations, reducing the risk of tangling in boring or external turning. Select the chipbreaker and grade according to workpiece material and the chosen turning strategy to maximise both productivity and process stability. The system approach—indexable insert, suitable outside holder or boring bar, shim/clamping set and replacement screws—simplifies tool management and spare-part logistics in the workshop.

FAQ

What materials is this insert suited for?
The CFGTL2020- AH874 Tungaloy indexable insert is engineered for heat-resistant alloys and other demanding materials; the PVD-coated AH874 grade provides high hot hardness for such applications.

Is the insert compatible with my existing holders?
Compatibility depends on holder form, free angle, tolerance class, fastening, size and thickness; the insert conforms to ISO L2020- dimensions and seats in holders designed for that family.

How does the chipbreaker affect machining?
The single-sided chipbreaker on this insert promotes predictable chip formation, improving evacuation and reducing entanglement during both external and internal turning.

Can this insert be used for internal boring as well as external turning?
Yes; the geometry and chip control make the insert suitable for both external turning and certain internal operations when paired with an appropriate boring bar.

What does the cylindrical hole with countersink mean for clamping?
The cylindrical hole plus one-sided countersink (40°–60°) provides secure mechanical location and tightening, ensuring repeatable seating and consistent cutting forces.
