DDQN R2020K ISO turning insert — rhombic, 55° cutting geometry, Tungaloy

The DDQN R2020K is an ISO‑standard rhombic turning insert designed for external and internal turning, compatible with holders that match its form, clearance and dimensional tolerances.

• ISO‑standard rhombic insert R2020K
• Solid carbide grade for long tool life
• 15° clearance angle, 55° cutting geometry
• Compatible with standard turning holders

Engineered to deliver consistent turning results

The DDQNR2020K insert is manufactured from cemented carbide to provide a reliable balance of toughness and wear resistance. Its rhombic geometry and 55° approach angle allow for versatile machining of external and internal profiles while maintaining a compact cutting edge suited to medium‑duty operations. The 15° clearance angle reduces rubbing and helps to preserve surface finish, making the insert appropriate for operations where dimensional consistency and low vibration are required. The ISO‑based designation ensures straightforward replacement and comparability across standard toolholder systems.

Simple integration with widely used holder systems

Compatibility is ensured by matching form, clearance, tolerance class, fixation method, size and thickness; the insert is intended to be used as part of a system consisting of the ISO turning insert, a suitable external holder or boring bar, an underlay/clamping set and spare screws. The version supplied has no chipbreaker and no hole, which favours applications where a uninterrupted cutting edge is preferred and chip control is managed by cutting parameters and machine stability. This configuration is particularly effective in stable setups and when paired with holders designed for rhombic inserts.

A dependable choice for productive workshops

Specifically selected for routine and repeatable turning tasks, the plate offers predictable wear behaviour and contributes to reduced tool change frequency when properly matched to workpiece material and machining conditions. The robust carbide grade supports steady performance under standard cutting speeds, while the ISO conformity aids inventory management and rapid replacement. Together, these factors support improved uptime and a consistent surface quality, aligning with shopfloor aims for higher productivity and repeatable results.

FAQ

What applications suit this insert best?
The DDQNR2020K turning insert is suitable for external and internal turning tasks where a rhombic geometry and a 55° approach angle are required, and where chip control can be achieved through process parameters.

Is the insert compatible with standard holders?
Compatibility depends on matching form, clearance, tolerance, fastening, size and thickness; the DDQNR2020K is ISO‑standardised to facilitate use with standard holders when these criteria are met.

Does the insert have a chipbreaker or fixing hole?
This variant is supplied without a chipbreaker and without a hole, so holders and cutting conditions should be selected accordingly to manage chips and clamping.

Which material is the insert made from and what does that mean for wear?
The insert is produced from cemented carbide, offering a balance of hardness and toughness that supports good wear resistance and stable edge retention under typical turning conditions.

How is the insert identified for ordering or stock control?
Refer to the manufacturer article number 6802960 or the manufacturer SKU TUN6802960 when ordering the DDQNR2020K insert to ensure an exact match.
