CFGT L2020- AH868 indexable insert for turning by Tungaloy

The CFGTL2020- AH868 Tungaloy indexable insert is an ISO‑standard turning insert designed for demanding external and internal turning of heat‑resistant alloys and other challenging materials.

• PVD‑coated carbide for high temperatures
• Single‑sided chipbreaker for controlled chips
• 25° clearance angle, rhombic shape for versatility
• ISO compatibility, 2.38 mm plate thickness

Maintain process reliability when machining heat‑resistant alloys

The combination of a PVD‑coated surface and a wear‑resistant carbide substrate in grade AH868 delivers sustained cutting performance at elevated temperatures. This cutting grade is formulated for high hot‑hardness and a stable cutting edge, which reduces flank wear and helps keep dimensional drift within tight tolerances. For production environments where cycle time and predictable tool life determine throughput, the engineered wear resistance translates directly into fewer tool changes and steadier component quality.

Controlled chip formation and improved surface integrity

The single‑sided chipbreaker geometry provides consistent chip control under a range of cutting conditions, reducing the risk of built‑up edge and erratic chip shapes. The rhombic insert form with an included angle of 80° and a 25° clearance angle offers a balance between edge strength and access to features, which benefits both heavy roughing and finish passes. As a result, the insert supports improved surface finish and reduced secondary operations, enhancing overall process economy.

Fast, reliable clamping and predictable fit across ISO holders

Compatibility is determined by form, clearance angle, tolerance class, attachment and plate size; this ISO series is engineered for straightforward interchange in standard external holders or boring bars when the correct seat and fastening are used. The plate’s 2.38 mm thickness and the central mounting with a cylindrical hole plus single‑side countersink (40°–60°) ensure secure clamping and repeatable positioning. This design minimises set‑up time and helps maintain concentricity and run‑out control during tool changes.

Practical advantages for workshop productivity

Adopting this insert supports a predictable tool‑life strategy: the PVD coating limits diffusion wear while the substrate resists mechanical damage, allowing stable cutting at raised cutting speeds where applicable. The grade and geometry selection strategy—matching AH868 to heat‑resistant alloys and tougher workpiece materials—helps to reduce rework and scrap. For job shops and production lines alike, the net effect is fewer interventions, lower tooling overhead and steadier delivery of parts to downstream processes.

FAQ

What materials is this insert suited for?
The insert in grade AH868 is formulated for heat‑resistant alloys and other demanding materials; the PVD‑coated carbide substrate offers high hot‑hardness for such applications.

How does the chipbreaker affect machining?
The single‑sided chipbreaker promotes controlled chip formation, improving evacuation and reducing the likelihood of built‑up edge during turning operations.

Which holders are compatible with this ISO insert?
Compatibility depends on holder form, clearance angle and fastening; the ISO profile, 2.38 mm thickness and central hole design permit use with standard external holders and boring bars when the correct seat and clamping hardware are used.

Is the insert suitable for finishing passes?
Yes — the combination of a stable cutting edge and the rhombic shape with a 25° clearance angle supports fine surface finishes when the cutting parameters are optimised.

What is the manufacturer SKU and article number for ordering reference?
Reference Manufacturer SKU: TUN6801630 and Article number: 6801630 when enquiring about the CFGTL2020‑ AH868 insert.
