DDQN L2020K turning insert by Tungaloy — carbide, 15° relief

DDQNL2020K is an ISO‑standard rhombic carbide insert designed for external and internal turning, compatible with holders that match form, clearance angle, tolerance class, fastening, size and thickness

• ISO‑standard rhombic insert, size L2
• Carbide grade construction, reliable wear resistance
• 15° relief angle for versatile turning
• Thickness 2.38 mm, no central hole

Consistent fit for reliable machining results

The insert is manufactured to ISO tolerances so it mates predictably with standard external holders and boring bars; compatibility depends on matching form, clearance angle, tolerance class, fastening method, size and thickness. This standardisation reduces setup time, limits machining variation and supports repeatable component quality. The rhombic geometry and specified dimensions enable straightforward replacement and predictable seating in compatible toolholders, helping to maintain cycle times and lower the risk of unplanned downtime.

Geometry optimised for stability and surface quality

A defined 15° relief combined with the rhombic form provides a balance between cutting edge strength and accessibility for finishing passes. The 2.38 mm plate thickness contributes to edge support during heavier cuts, while the lack of a central hole simplifies seating options in many clamping systems. Together, these characteristics support stable chip formation and improved surface finish in both external and internal turning, particularly when the correct chipbreaker and grade are selected for the workpiece material.

Practical selection and process guidance for efficient turning

Select the chipbreaker and grade according to workpiece material and machining conditions to unlock productivity benefits: the right combination reduces machining forces and extends edge life. For general turning applications, choose a grade and chipformer matched to the workpiece to benefit from predictable tool life and consistent component tolerances. If material compatibility or process windows are unclear, the insert's ISO designation and measured parameters provide a reliable basis for optimisation and tool exchange strategies within a production environment.

FAQ

What holder characteristics must match for correct fit?
Correct seating requires matching the holder's seat form, clearance (free) angle, tolerance class, fastening method, size and plate thickness; these determine compatibility with the DDQNL2020K insert.

Is the insert suitable for internal turning as well as external turning?
Yes, the insert is designed for both external and internal turning operations when used with an appropriate holder and chosen chipbreaker or grade.

What does the 15° relief mean for machining?
A 15° relief reduces rubbing behind the cutting edge, helping to lower cutting forces and improve surface finish while maintaining edge support for stable cuts with the DDQNL2020K.

Which materials can be machined with this type of insert?
Material suitability depends on the selected grade and chipformer; the DDQNL2020K body is carbide and allows a broad material coverage when combined with the correct grade and chipbreaker.
