CFGT L2020- AH881 Tungaloy indexable insert — ISO indexable turning insert for turning, rhombic 80°

A CFGT L2020- AH881 indexable insert engineered for ISO-compliant turning, designed to tackle heat-resistant alloys and other demanding materials with reliable edge stability and repeatable mounting.

*PVD-coated carbide AH881 for high hot hardness *Rhombic insert with 80° included angle *Cylindrical hole with one-sided countersink *ISO-compatible for standard turning holders

Predictable performance on heat-resistant alloys

The PVD-coated AH881 grade, applied to a carbide substrate, is tailored for high-temperature strength and a stable cutting edge, offering predictable wear behaviour when machining heat-resistant alloys. The PVD coating reduces adhesion and increases thermal resistance, which translates into longer cutting times between indexings and improved process economy. For users less familiar with coatings: PVD (physical vapour deposition) forms a very thin, hard film that protects the carbide substrate and helps maintain the cutting geometry at elevated temperatures.

Accurate fit and repeatability for process stability

Built to the ISO indexable insert system, the rhombic geometry with an 80° included angle and a 25° clearance ensures reliable seat contact and defined cutting engagement. The cylindrical mounting hole with a one-sided countersink (40°–60°) secures the insert in the pocket and minimises micro-movement under load, supporting consistent surface finish and dimensional control. Compatibility is governed by form, clearance angle and tolerance class, so selection within the ISO family guarantees interchangeability and simplified tool management.

Controlled chips and secure clamping for uninterrupted production

A single-sided chipbreaker combined with the insert’s geometry promotes effective chip control, reducing the risk of entanglement and improving surface integrity on the workpiece. The stable clamp interface and standardised hole style facilitate fast insert changes, shortening downtime and supporting a continuous production rhythm. For operations prioritising throughput, these characteristics deliver measurable gains in efficiency while preserving workpiece quality.

FAQ

What materials is this insert intended for? The CFGT L2020- AH881 insert is designed primarily for heat-resistant alloys and similar demanding materials; the PVD-coated AH881 grade provides increased hot hardness for such applications.

How does the insert fix to the holder? Clamping is achieved via the cylindrical hole with a one-sided countersink and a standard ISO seat; this configuration ensures a secure fit in compatible turning holders and reduces micro-movement during cutting.

What advantage does the AH881 coating provide? The PVD-coated AH881 grade offers superior thermal resistance and edge stability, which extends cutting life and improves process reliability when machining high-temperature alloys.

Is this insert compatible with standard ISO turning toolholders? Yes, the insert conforms to ISO standards for turning indexable inserts; compatibility depends on matching form, clearance angle and size (L2) with the chosen holder.

Which chip control can be expected? The single-sided chipbreaker promotes controlled chip formation for many turning tasks, aiding safety and surface quality while decreasing the likelihood of chip-related interruptions.
