CGWT R2020- CGWTR2020- Tungaloy turning insert for turning, rhombic R2, 30° relief

The CGWTR2020- is an ISO-standard rhombic turning insert designed for external and internal turning, engineered for secure clamping and reproducible cutting performance.

• ISO-standard rhombic insert, R2 corner radius
• 30° relief angle for stable cutting action
• Carbide construction for wear resistance
• Cylindrical hole with countersink for secure clamping

Stable cutting performance through optimised geometry

The insert's rhombic form and an 80° approach angle combine to provide a balance between cutting strength and accessibility in confined geometries. Made from carbide, the body offers high wear resistance and predictable tool life under steady cutting conditions. The 30° relief angle reduces rubbing at the flank, improving surface quality and lowering cutting forces. These design choices result in a reliable cutting edge that supports consistent cycle times and fewer unscheduled tool changes.

Quick mounting and secure clamping reduce setup time

Compatibility is guided by ISO dimensions: the central cylindrical hole with a one-sided countersink (40°–60°) enables standard clamping methods and repeatable seating. With a 2.38 mm plate thickness, the insert provides a robust seat in matched holders, while the single-sided chipbreaker helps control chip flow on the active cutting face. Together, these features simplify insertion into the tool holder and ensure a secure fit when paired with the appropriate underlay, clamping set and replacement screws.

Flexible application for external and internal turning

Engineered for both external turning and internal turning, selection of chipbreaker style and carbide grade should follow the workpiece material and machining stability. The ISO designation and standardised tolerance classes make it straightforward to match the insert to compatible holders and tool systems. The single-sided chip control encourages consistent swarf formation in many turning scenarios, which supports safer, more efficient machining cycles.

Inventory efficiency and dependable replacement strategy

Standardised dimensions and ISO naming simplify stock management and reorder processes. The clearly specified R2 corner radius and ISO code ensure rapid replacement without lengthy requalification. The insert is part of a system: an ISO turning insert, an appropriately shaped external holder or boring bar, plus the necessary underlay and clamping components, which together create a repeatable and maintainable machining solution. This system approach reduces downtime and supports predictable production planning.

FAQ

What machining tasks suit this insert best? The CGWTR2020- turning insert by Tungaloy is suited to both external and internal turning operations where a rhombic geometry and an R2 corner radius are appropriate.

How is the insert secured in the holder? Securing is via the central cylindrical hole with a one-sided countersink (40°–60°); the CGWTR2020- is designed for standard clamping systems and repeatable seating.

Which relief and approach angles does the insert offer? This insert features a 30° relief angle and an 80° insert angle, providing a compromise between cutting access and edge strength.

Is this a carbide grade product and what are the benefits? Yes; the insert is manufactured from carbide, giving improved wear resistance and consistent performance during sustained turning cycles.

Can the chip formation be influenced by insert choice? Chip control is provided by a single-sided chipbreaker on the active face; selecting the appropriate chipbreaker and grade tailors swarf behaviour for specific turning tasks.
