DDQNL2020K ISO turning insert, rhombic L2, 15° relief angle — Tungaloy

DDQNL2020K is an ISO‑standard rhombic turning insert designed for versatile external and internal turning applications in production environments

• ISO‑standard rhombic insert L2
• 15° relief angle for general turning
• Solid carbide for edge stability
• No hole design for stable clamping

Reliable geometry for consistent turning results

The DDQNL2020K insert is manufactured to ISO norms and offers a rhombic L2 form with an included angle of 55°, delivering predictable cutting kinematics for many turning tasks. The 15° relief angle reduces rubbing at the flank face and supports a reliable shear plane, while the solid carbide substrate ensures wear resistance and repeatable edge life. These characteristics translate into steadier part tolerances and reduced rework rates in batch production.

Clear guidance on compatibility and clamping benefits

Compatibility with toolholders depends on form, relief angle, tolerance class, fastening, size and thickness; the insert’s no hole configuration requires a matching seat and clamp on the holder for secure fixation. Choosing a holder rated for rhombic L2 inserts avoids misalignment and supports stable machining. The absence of a chipbreaker on this grade keeps the cutting edge simple and predictable; select an appropriate chip control solution based on workpiece stability and material.

Application focus and selection advice

Engineered for turning, this ISO series covers both external and internal operations — the insert performs well when the correct chipbreaker and grade are chosen to suit the workpiece and machining parameters. The solid carbide construction is favourable where dimensional consistency and edge strength are required. For process optimisation, match cutting data and coolant strategy to the component material and machine rigidity to exploit the insert’s potential without unnecessary tool wear.

FAQ

What applications is this insert suited for?
The DDQNL2020K insert from Tungaloy is intended for external and internal turning, offering a rhombic L2 geometry suited to a wide range of turning operations.

How does the no‑hole design affect clamping?
A no‑hole configuration requires a compatible seat and clamping system on the holder to ensure the DDQNL2020K insert is held securely for stable cutting.

Which materials should be considered when selecting this insert?
Select the chipbreaker and grade to match the component material and machining stability; the carbide substrate of the DDQNL2020K provides edge strength for demanding turning tasks.

What are the key dimensions to check for holder compatibility?
Verify the shape (rhombic L2), thickness (2.38 mm), relief angle (15°) and included angle (55°) against the holder specification to ensure correct fit and clamping.
