CFGT R2020- AH927 Turning Insert (ISO indexable) — Tungaloy

The CFGT R2020- AH927 is an ISO‑standard indexable turning insert designed for external and internal turning, offering a wear‑resistant PVD‑coated carbide grade for reliable process security.

• ISO indexable rhombic insert R2
• PVD-coated carbide grade AH927
• 25° relief angle for versatile turning
• Cylindrical hole with one-sided countersink 40°–60°

Delivering predictable cutting performance and lower process costs

The PVD‑coated carbide composition of this indexable plate provides a balance between wear resistance and edge toughness, reducing flank wear and unexpected chipping during continuous turning. As a result, cycle times become more predictable and tool changes less frequent, which improves overall productivity. The combination of a sharp cutting edge and a wear‑resistant coating translates into fewer rejects and a superior surface finish on turned components.

Geometry and mounting designed for secure clamping and repeatability

The rhombic form in R2 size, the 25° relief angle, and the specified thickness of 2.38 mm are all chosen to match common ISO turning holder geometries. The insert is supplied with a cylindrical hole and a one‑sided countersink (40°–60°) to accommodate screw clamping and ensure stable seating in the pocket. Compatibility with a given holder is determined by shape, relief angle, tolerance class, fastening method, size and thickness, so the insert integrates into standard ISO clamping systems with high repeatability.

Material adaptability and recommended applications

Engineered for turning, the AH927 grade performs well where a sharp cutting edge and process security are required. The plate is intended for both external and internal turning operations; selection of the correct single‑sided chipbreaker should be matched to the workpiece material, machining strategy and machine stability. The PVD layer enhances oxidation resistance at elevated temperatures and supports consistent performance across a broad range of turning tasks.

Operational advantages: uptime, surface quality and tool life

Using a uniform ISO‑series insert like this reduces setup complexity and shortens changeover times, contributing to higher net machining time. The combination of PVD coating, robust carbide substrate and precise geometry yields longer service life and improved surface integrity of finished parts. Where fine finishing or stable roughing cycles are required, this insert offers a controlled chip form and dependable cutting behaviour that supports predictable maintenance intervals and reduced total cost of machining.

FAQ

What turning operations is this insert suitable for?
The CFGT R2020- AH927 turning insert is intended for both external and internal turning, with a single‑sided chipbreaker to be selected according to the workpiece material and machining stability.

How does the AH927 grade affect tool life?
The AH927 PVD‑coated carbide offers improved wear resistance and edge stability; this grade helps extend tool life and maintain surface finish under continuous turning conditions.

Which clamping method is required for this insert?
The insert features a cylindrical hole with a one‑sided countersink (40°–60°) and is designed for screw clamping into ISO‑compatible holders; secure seating ensures repeatable positioning.

Is the insert compatible with standard ISO holders?
Yes — the ISO‑series designation and specified form, relief angle, size and thickness ensure compatibility with ISO indexable turning holders when the correct tolerance class and fastening are used.

What should be considered when choosing the chipbreaker?
Select the chipbreaker based on material, cutting parameters and rigidity: the single‑sided design works well when combined with a suitable grade and appropriate feed and speed to control chip formation.
