CFGT R2020- AH913 – Tungaloy indexable insert for turning (rhomboid R2, 25° relief)

The CFGTR2020- AH913 Tungaloy indexable insert provides a wear- and fracture-resistant solution for general turning, designed for compatibility with ISO external holders and boring bars.

• PVD-coated AH913 for process stability
• Rhomboid R2 form for versatile turning
• 25° relief angle for controlled cutting action
• Cylindrical hole with countersink for secure mounting

Greater process reliability through wear-resistant grade and coating

The PVD-coated carbide grade AH913 is engineered to reduce flank wear and minimise edge breakouts in demanding turning cycles. By combining a hard coating with a tough carbide substrate, the insert delivers consistent cutting behaviour over longer tool life, which translates into fewer tool changes and improved uptime. This stability is particularly valuable in medium- to high-volume production where reproducible component tolerances and surface quality are required. The result is a predictable cutting process that supports efficient shop-floor planning and cost control.

Accurate fit and secure clamping for repeatable results

Built to ISO specifications, the rhomboid R2 geometry and the 25° relief guarantee predictable shear conditions and chip formation when used with corresponding holders. The insert features a cylindrical hole with a single-sided countersink (40°–60°) to ensure reliable seating and repeatability during indexation. Compatibility is determined by form, relief, tolerance class, fastening and thickness, so the insert integrates into standard systems comprising an external holder or boring bar, shim/locking set and replacement screws. That system-level approach simplifies tool management and reduces setup time.

Practical durability and efficient chip control for turning operations

The design includes a one-sided chipbreaker tuned for common turning tasks, helping to control chip flow and prevent entanglement on the workpiece. The combination of chipbreaker geometry and the AH913 grade supports a sharp cutting edge without sacrificing robustness, which is advantageous when switching between finishing and semi-finishing passes. For manufacturers aiming to balance surface finish and throughput, this insert improves process security and lowers the risk of unexpected tool failure, contributing to steady production quality and economic operation.

FAQ

What work is this insert intended for?
This insert is suitable for turning; the CFGTR2020- AH913 insert from Tungaloy is specified for both external and internal turning applications when paired with the correct holder.

How does the AH913 grade improve tool life?
The AH913 PVD-coated carbide grade on the CFGTR2020- AH913 increases wear resistance and reduces the likelihood of edge chipping, delivering more consistent tool life under normal turning conditions.

Which holder features are required for correct mounting?
Compatibility depends on form, clearance angle, tolerance class, fastening method, size and thickness; the rhomboid shape and cylindrical hole with countersink demand a matching ISO external holder or boring bar.

Is the insert suitable for finishing passes?
Yes, the combination of a sharp cutting edge and controlled chipbreaking makes the insert appropriate for finishing and semi-finishing operations, providing a balance between surface quality and robustness.
