CFGT R2020- AH926 Tungaloy indexable insert for Turning — ISO rhombic R2, PVD carbide, 25° relief

A CFGT R2020- AH926 indexable turning insert, ISO-standard rhombic R2 plate engineered for accurate seating and consistent chip control in external and internal turning operations

• PVD-coated carbide grade AH926
• ISO rhombic R2 plate, 80° included angle
• 25° relief angle for sharp cutting edge
• Cylindrical hole with single-sided countersink (40°–60°)

Proven edge stability for consistent production

The CFGTR2020- AH926 insert pairs a PVD coating with a high-performance cemented carbide substrate to deliver a balance of wear resistance and edge sharpness. The selected grade AH926 is formulated for resistance to flank wear and chipping, which supports process security in mixed production environments. The PVD film reduces friction and thermal loading at the cutting zone; this translates into longer effective tool life and fewer unplanned index changes, helping to maintain a steady production flow and predictable machining results.

Reliable fit and mechanical rigidity for turning tasks

Designed to the ISO-standard geometry, the plate’s rhombic R2 form and 25° relief angle determine compatibility with a wide range of holders. The insert’s 80° included angle and a thickness of 2.38 mm offer a compromise between a sharp cutting line and sufficient supporting mass, suitable for both external and internal turning where rigidity is moderate to high. The cylindrical hole with a single-sided countersink (40°–60°) ensures a secure clamp seat and even load distribution; compatibility with a holder depends on form, relief angle, tolerance class, fastening method, size and thickness.

Controlled chips and application guidance for efficient machining

Equipped with a single-sided chipbreaker, this indexable plate promotes predictable chip formation and evacuation. The chipbreaker’s geometry fragments chips into manageable lengths, reducing entanglement and facilitating coolant access, which helps to improve surface finish and reduce heat concentration. Select the chipbreaker and grade in relation to workpiece material and machining stability: softer, ductile materials typically need a different approach than interrupted cuts or unstable setups. Use this plate where a sharp cutting edge and steady, reproducible performance are priorities.

FAQ

Which holders are compatible with this ISO plate?
Compatibility depends on holder geometry and clamp design; the plate fits holders that accept ISO rhombic R2 inserts with a 25° relief angle and a matching clamping arrangement. The CFGTR2020- AH926 requires a holder that accommodates a cylindrical hole with a single-sided countersink.

For which materials is this insert suitable?
The PVD-coated cemented carbide AH926 is a wear- and chipping-resistant grade intended for a broad range of steels and mixed materials where a sharp cutting edge and reliable process security are needed.

What advantage does the single-sided chipbreaker provide?
The single-sided chipbreaker on this plate improves chip control by producing short, controllable chips and aiding coolant access, which enhances surface finish and reduces heat build-up during turning operations.

Can this insert be used for interrupted cuts?
Use in interrupted cuts depends on machine and setup rigidity; the plate’s 25° relief and 2.38 mm thickness provide moderate edge strength—suitable for light to medium interruptions if clamping and stability are adequate.

How does the PVD coating affect tool life and performance?
The PVD coating increases wear resistance and reduces friction at the cutting edge, which typically extends tool life and supports consistent machining results under variable production conditions.
