DDQN R2020K rhombic turning insert, 15° clearance — Tungaloy

DDQN R2020K is an ISO‑standard rhombic insert engineered for reliable external and internal turning in general workshop and production environments.

*ISO-standard rhombic insert *15° clearance angle for reliable chip flow *Carbide grade for stable wear resistance *Compatible with standard holders and clamps

High‑precision geometry for consistent process security

The rhombic design with a 55° included angle and a 15° clearance provides a predictable cutting geometry that supports stable tool engagement. ISO standardisation ensures repeatable fitment and interchangeability with holders that match form, tolerance class, fastening and thickness. This process‑oriented geometry reduces setup variability and contributes to consistent surface quality during both light finishing and heavier roughing passes.

Clear guidance on holder compatibility and selection

Compatibility depends on form, relief angle, tolerance and fastening. The insert is supplied without a chipbreaker, which allows selection of an appropriate chip control solution based on the workpiece material and cutting conditions. For external and internal turning, choose a holder whose seat matches the rhombic form and the R2 size; correct seating and clamp torque maintain cutting edge position and reduce vibration, which in turn extends insert life and improves dimensional repeatability.

Durable carbide construction and application range

Manufactured from carbide, the insert combines hardness and toughness for extended tool life in turning operations. The 2.38 mm plate thickness and R2 size are suited to many standard turning tasks where compact insert geometry is required. The ISO‑rated series supports a wide range of steels and non‑ferrous materials when paired with the matching grade; selecting the correct grade and cutting data enables efficient material removal while maintaining edge stability and surface finish. The DDQNR2020K designation identifies the plate geometry and system compatibility for straightforward toolroom integration.

FAQ

What materials can this insert machine effectively? The DDQNR2020K Tungaloy insert is a carbide insert intended for turning; pairing it with the correct grade allows machining of a broad range of materials typically encountered in turning operations.

Is a chipbreaker included with the insert? No, the insert is supplied without a chipbreaker; the absence of a built‑in chip former enables selection of a chip control solution tailored to the workpiece material and cutting strategy.

How should the insert be matched to a holder? Match the rhombic form, R2 size, 15° clearance and plate thickness to a compatible holder; correct seating, clamp set‑up and tolerance class ensure positional accuracy and repeatable performance with the DDQNR2020K Tungaloy insert.

What are the physical dimensions relevant for fixture planning? Key dimensions are the plate thickness of 2.38 mm, plate form R2 and the 55° included angle; these values define seat and clamp requirements for compatible turning holders.
