CFGT L2020- AH873 turning insert by Tungaloy

A robust, ISO‑compliant CFGTL2020- AH873 insert engineered for turning heat‑resistant alloys and other demanding materials with a stable cutting edge and reliable chip control

• PVD‑coated carbide grade AH873
• Optimised for heat‑resistant alloys
• 25° clearance angle for reduced rubbing
• Rhombic L2 form, thickness 2.38 mm

Faster, more predictable metal removal through material and coating

The combination of a PVD‑coated carbide substrate and the AH873 grade delivers elevated hot hardness and abrasion resistance, which together reduce flank wear during extended cuts on temperature‑sensitive alloys. This results in fewer tool changes, more stable cycle times and improved process efficiency. For production environments where machining windows are narrow, the insert’s coating contributes to consistent dimensional stability and repeatable performance across batches.

ISO conformity and straightforward mounting to control inventory

As an ISO‑compliant turning insert, compatibility with holders is defined by form, clearance, tolerance class, fastening method, size and thickness. The insert is supplied with a cylindrical hole plus single‑side countersink (40°–60°) to match standard clamping systems and replacement screws. Standardisation reduces the number of bespoke parts in stock and simplifies tool change procedures, shortening setup times and lowering logistic complexity on the shop floor.

Geometry that supports chip control and surface quality

The rhombic L2 form, combined with a single‑sided chipbreaker, is configured to guide chips away from the cutting zone during both external and internal turning operations. The specified 25° clearance angle prevents flank contact and rubbing, while the insert’s 2.38 mm thickness and 80° included angle provide a balance of rigidity and accessibility for shoulder cuts and profiling. The result is improved surface finish with lower risk of built‑up edge when machining tough materials.

Practical advantages for workshop productivity and process reliability

Selecting this insert reduces unplanned downtime through a stable cutting edge and predictable wear behaviour; the AH873 grade is tailored for high‑temperature applications and maintains edge integrity under thermal and mechanical stress. The insert’s design supports a broad range of turning tasks, from roughing to semi‑finishing, minimising tool inventory while maintaining machining flexibility. For challenging materials, the insert offers an economical route to repeatable results and measurable reductions in cycle variation.

FAQ

What materials is this insert best suited for?
The insert is specified for heat‑resistant alloys and other demanding workpiece materials; the AH873 PVD‑coated carbide grade maintains hardness at elevated temperatures for reliable cutting performance.

How is the insert fixed to a toolholder?
Mounting follows ISO conventions: compatibility is determined by form, clearance, tolerance class, fastening method, size and thickness; this insert features a cylindrical hole plus single‑side countersink (40°–60°) to match standard clamping systems.

Does the geometry support both external and internal turning?
Yes; the rhombic L2 form and the single‑sided chipbreaker are suited to both external and internal turning operations where chip control and access are required.

What benefits does the PVD coating provide?
The PVD coating on the carbide substrate increases wear resistance and thermal stability, extending tool life and improving process consistency when machining hot or abrasive alloys.

Can the insert reduce tool change frequency?
The AH873 grade’s stable cutting edge and high hot hardness contribute to more predictable wear and fewer unexpected tool changes, supporting higher machine uptime.
