DCLNL2020K — DCLN L2020K turning insert by Tungaloy

The DCLNL2020K is an ISO‑standard rhombic turning insert designed for external and internal turning operations with standard clamping systems

• ISO‑standard rhombic insert, 55° geometry
• Carbide construction for reliable wear resistance
• 7° clearance angle for consistent surface finish
• Suitable for external and internal turning operations

Precision compatibility for smooth changeovers

The combination of an ISO‑standard designation and a rhombic, 55° approach angle ensures straightforward interchangeability in industrial turning fixtures. Because the insert follows ISO norms, compatibility with matching holders is determined by form, clearance, tolerance class, fastening and thickness, which reduces setup time and supports consistent tool indexing. The 2.38 mm plate thickness and L2 size offer reliable seating in the clamp, while the absence of a central hole simplifies installation on holders designed for pocket clamping. This standardised fit is particularly valuable where frequent insert changes are required for high‑mix production.

Durable cutting performance and material handling

Built from solid carbide, the insert is designed for stable chip formation and extended tool life under industrial turning conditions. The geometry and negative clearance help deliver an improved surface finish on turned components, while the solid carbide body contributes to heat resistance and edge stability during interrupted cuts. When a chip‑control feature is required, the lack of an integrated chipbreaker means an appropriate breaker and grade should be selected to match the workpiece material and machining strategy, enabling optimised productivity in both roughing and finishing passes.

System guidance and practical selection tips

The insert is part of a complete ISO turning plate system comprising the insert, a matching outside holder or boring bar, and the necessary locating and clamping components. Selection of the correct holder depends on form, tolerance class and fastening type; choosing the correct combination ensures repeatable clamping forces and consistent cutting conditions. For applications where chip control and heat management are critical, pair the plate with a suitable chipbreaker and pick a carbide grade matched to the workpiece. Technical documentation and compatibility charts can assist in selecting the correct holder geometry and screw set for secure retention and predictable repeatability.

FAQ

What holder characteristics must be matched for reliable clamping?
Matching the holder requires attention to form, clearance angle, tolerance class, fastening and plate thickness; the DCLNL2020K insert is designed to seat securely when these parameters correspond to the holder pocket.

Is this insert suitable for internal turning as well as external turning?
Yes; the rhombic geometry and ISO format make the insert appropriate for both external and internal turning when used with a compatible boring bar or internal holder.

How should chip control be addressed given there is no chipbreaker on the plate?
Because the DCLNL2020K does not include an integrated chipbreaker, select a matching chipbreaker and carbide grade suited to the workpiece material and operation to ensure controlled chip evacuation and consistent surface finish.

What does the 7° clearance mean for surface finish and tool life?
A 7° clearance reduces friction at the flank face and helps achieve a consistent surface finish, while also contributing to predictable edge engagement that supports longer tool life under correct cutting conditions.

Are original spare parts and screws available for installation and replacement?
Spare screws and clamping components matching the ISO system are required for correct installation; the insert is part of a standardised system that permits straightforward sourcing of replacement clamping kits.
