CGWT R0040- AH968 indexable turning insert — ISO rhombic, 80° | Tungaloy

CGWT R0040- AH968 is an ISO rhombic indexable turning insert engineered for reliable external and internal turning applications in industrial machining.

• ISO rhombic insert, 80° cutting angle
• PVD-coated carbide AH968 for wear resistance
• 30° clearance angle for stable cutting
• Cylindrical hole with 40°–60° countersink

Maximised tool life through coating and substrate

The combination of a PVD-coated carbide substrate and the AH968 grade provides a balance of wear resistance and edge robustness that favours stable production. The PVD-coated carbide surface reduces abrasive wear and supports a sharp cutting edge, which translates into longer tool life and fewer indexings. This effect is particularly relevant in series production, where component consistency and reduced downtime contribute directly to manufacturing efficiency.

Consistent chip control and process reliability

A dedicated one-sided chipbreaker on the insert assists in forming predictable chips and reduces the risk of chip entanglement in turning operations. The controlled chip formation supported by the chipbreaker leads to safer machining and steadier surface quality with fewer interruptions. For operations requiring reproducible results, this characteristic enhances process security and helps to maintain throughput under varying cut conditions.

Secure seating and mechanical rigidity

The insert features a cylindrical hole with a one-sided countersink (40°–60°) to ensure precise seating and positive clamping in compatible holders. Together with the 4.76 mm thickness and 30° clearance angle, the design contributes to mechanical rigidity and vibration damping during cutting. Compatibility with the toolholder is determined by form, clearance, tolerance class, fixing method, size and thickness, so the insert integrates into established ISO-based tool systems with predictable results.

Precision finishing with small corner radii

The rhombic R0 geometry and the 80° included angle allow fine-detail turning and controlled engagement at the cutting edge, making the insert suitable where small corner radii and accurate profiles are required. Selecting the appropriate chipbreaker and the AH968 grade according to material, cutting parameters and machine stability enables both roughing and finishing strategies while maintaining consistent surface integrity and production economy.

FAQ

What applications is this insert intended for?
The CGWT R0040- AH968 indexable turning insert is designed for external and internal turning; the combination of AH968 grade and a dedicated chipbreaker supports both roughing and finishing strategies in industrial machining.

Which holder features are required for correct fitment?
Compatibility is determined by form, clearance, tolerance class, fixing method, size and thickness; the insert’s cylindrical hole with one-sided countersink ensures secure seating in ISO-compatible holders designed for R0040- inserts.

How does the AH968 grade affect performance?
The AH968 PVD-coated carbide provides enhanced wear resistance and edge strength, reducing flank wear and improving process reliability for series production.

Can this insert be used for interrupted cuts?
Yes — the robust edge and PVD coating of the AH968 grade, together with the insert’s geometry, support stable performance under interrupted-cut conditions when matched with suitable cutting parameters.

What chip control can be expected?
The one-sided chipbreaker is engineered to promote predictable chip formation and evacuation, which improves surface quality and reduces the likelihood of chip-related disturbances during turning.
