CFGT R2020- AH924 — ISO turning insert, PVD-coated carbide, 25° relief | Tungaloy

The CFGTR2020- AH924 Tungaloy turning insert is an ISO-standard indexable insert engineered for external and internal turning, offering a wear-resistant PVD-coated carbide grade for process-stable machining.

• ISO-standard turning insert, rhombic R2
• PVD-coated carbide grade AH924
• 25° relief angle for secure cutting
• Cylindrical hole with 40°–60° countersink

Consistent cutting performance with a wear-resistant grade

The PVD-coated carbide grade AH924 combines a resistant coating with a substrate designed to sustain a sharp cutting edge and resist chipping under interrupted cuts. The coating reduces flank wear and thermal softening, which translates into more consistent surface finish and fewer insert changes. For production environments where repeatability matters, the insert’s composition supports longer tool life and predictable tool-change intervals, helping to keep cycle times stable and scrap rates low.

Stable clamping and geometry that supports process security

Compatibility with toolholders is determined by form, relief angle, tolerance class, fastening, size and thickness. The rhombic R2 profile and 25° relief angle ensure a defined cutting geometry that improves engagement control and reduces risk of unexpected edge failure. The insert’s cylindrical hole with a single-side countersink (40°–60°) provides secure seating in a variety of clamping systems, while the 2.38 mm thickness offers stiffness for medium-duty turning. These design choices reduce vibration and help maintain dimensional accuracy in both external and internal turning operations.

Efficient chip control and production advantages

Equipped with a one-sided chipbreaker, the insert supports controlled chip formation under many turning conditions, aiding evacuation and reducing entanglement in the work area. Clear chip control contributes to machine uptime and operator safety, and when combined with the AH924 grade, it delivers a balance between wear resistance and edge strength. This results in economic machining: fewer interruptions for insert replacement and stable output quality, which benefits batch processing and mixed-production workshops alike.

System-oriented selection and integration into the toolpack

The ISO insert is intended to form part of a system: select a matching outside holder or boring bar, the correct underlay/clamping set and the specified replacement screws to ensure full compatibility. When choosing the chipbreaker and insert size, align the selection with the workpiece stability and the intended cutting parameters—short, rigid setups favour higher feeds and fewer insert indexes, while longer overhangs may require gentler cutting conditions. The configuration described here supports straightforward integration into existing ISO-based toolholders and facilitates easy replacement and inventory management.

FAQ

What holder types are compatible with this ISO insert?
Compatibility depends on holder form, relief angle, tolerance class, fastening, size and thickness; the insert fits ISO-standard turning holders and compatible boring bars when those parameters match.

Is the AH924 grade suitable for interrupted cuts?
Yes, AH924 is specified as a wear- and break-resistant grade, offering a sharp cutting edge and enhanced process security for demanding turning tasks.

How does the one-sided chipbreaker affect machining?
The one-sided chipbreaker promotes controlled chip formation and evacuation, improving machine uptime and reducing the risk of chip-related surface damage.

What does the cylindrical hole with countersink provide?
The cylindrical hole plus 40°–60° single-side countersink ensures secure clamping and repeatable seat location in standard ISO clamping systems.

Which components complete the system for a working toolpack?
A matched outside holder or boring bar, an appropriate underlay/clamping set and the specified spare screws complete the ISO-system setup for correct assembly.
