CFGT R2020- CFGTR2020- turning insert, Tungaloy — carbide, 80° geometry

CFGTR2020- is an ISO‑standard rhomboid turning insert designed for external and internal turning applications where secure clamping and controlled chip formation are required.

• ISO‑standard rhomboid insert, size R2
• Carbide grade for stable cutting performance
• 80° cutting edge with 25° relief angle
• Cylindrical hole with 40°–60° countersink

Stable cutting performance for productive turning

The rhomboid insert is manufactured from carbide and features an 80° cutting geometry combined with a 25° relief angle, resulting in a robust cutting edge that resists deflection during heavier cuts. This geometry suits both finishing and medium‑duty roughing in conventional turning operations, offering improved tool life through reduced edge chipping. The 2.38 mm plate thickness increases stiffness at the cutting zone, which translates into more predictable machining behaviour and fewer interruptions for tool change. Compatibility with toolholders is determined by form, relief angle, tolerance class, attachment method, size and thickness, so the insert integrates into standard ISO tool systems without modification.

Predictable chip control and secure clamping

Equipped with a single‑sided chipbreaker, the insert promotes consistent chip formation and evacuation, reducing the risk of chip entanglement and improving surface finish on components. The central cylindrical hole with a single‑side countersink (40°–60°) provides reliable mechanical indexing and secure clamping, which keeps the insert seated correctly under varying cutting forces. These features collectively reduce machine downtime and make setup more efficient, while the ISO‑conformant design simplifies replacement and inventory management.

Practical guidance for selection and system setup

The ISO model series is intended to work as part of a complete system: ISO insert, an appropriate external holder or boring bar, a shim/clamp set and replacement screws. When selecting a cutting grade, match the chipbreaker and grade to the material and machining strategy; the supplied geometry is versatile, but the correct insert grade maximises performance for specific steels or alloys. For assessment of holder compatibility or grade recommendations, compatibility checks are available from Metav Werkzeuge and technical specifications should be consulted to ensure the selected insert meets process stability and surface finish targets.

FAQ

What holders are compatible with this insert?
Compatibility depends on the holder form and clamping design; the CFGTR2020- insert is ISO‑standard and will fit holders designed for rhomboid R2 inserts with a central cylindrical fastening hole and matching tolerance class.

Which materials is the insert suitable for?
The CFGTR2020- insert is a carbide grade designed for general turning tasks; selection of the exact carbide grade and chipbreaker variant should be based on the workpiece material and machining strategy to achieve optimal life and surface quality.

How does the chipbreaker affect machining?
The single‑sided chipbreaker on this insert promotes controlled chip curling and evacuation, reducing chip-related interruptions and improving surface finish during continuous turning operations.

What is the benefit of the 80° geometry?
An 80° cutting edge provides a strong cutting corner that withstands higher radial loads, offering better edge strength for medium cuts and improving overall process stability.

Is the insert supplied with mounting screws or shims?
The insert is part of an ISO system that typically includes the insert itself; suitable holders, shims/clamps and replacement screws should be selected to match the insert and toolholder combination.
