DCLNR2020K indexable turning insert — ISO rhombic R2, 7° relief, 55° lead angle (Tungaloy)

DCLNR2020K is an ISO‑compatible indexable insert for precision external and internal turning, designed to fit ISO holders where form, relief angle and tolerance class match the clamping system

• ISO rhombic insert R2
• 7° relief angle
• 55° lead angle for general turning
• Carbide body for reliable wear resistance

Accurate ISO fit for predictable clamping and repeatable results

The ISO standardisation of this rhombic indexable insert ensures straightforward selection and predictable interface geometry with ISO holders. The combination of a defined 7° relief angle and the 55° lead angle reduces unwanted rubbing and supports consistent cutting engagement, which directly benefits process stability and surface finish. Compatibility depends on holder form, tolerance class, fastening and the insert thickness, so the intended clamping system must be verified before installation.

Carbide construction that supports productivity and tool life

Manufactured from carbide, the insert delivers wear resistance and stable cutting behaviour under typical turning conditions. Carbide substrates provide thermal stability and edge robustness, which helps to maintain dimensional accuracy over extended production runs. Selecting the correct grade and, where available, a matching chipbreaker or coating will further extend service life and reduce changeover frequency, thus improving overall machining economy.

Designed for flexible external and internal turning applications

This rhombic insert is suitable for both external and internal turning when the geometry and holder type are appropriate. The insert is supplied without a chipbreaker and without a hole, offering freedom to pair it with holder styles and cutting strategies that match the component material and machinability. For materials with challenging chip control, a dedicated chipbreaker or adjusted cutting parameters should be chosen to secure reliable chip evacuation.

Practical system approach for consistent production workflows

Use the insert as part of a complete system comprising an ISO insert, a matched external holder or bar, a shim/clamp set and the required replacement screws; this arrangement promotes consistent clamping forces and repeatable insert seating. Clear identification of size R2 and plate thickness facilitates inventory management and quick replacement. When process reproducibility and reduced set‑up time are priorities, the standardised geometry and carbide construction support stable, productive turning operations.

FAQ

What holder types are compatible with this insert?
Compatibility depends on the ISO holder form, clamping concept and tolerance class; the DCLNR2020K Tungaloy indexable insert (SKU 6802879‑Tungaloy) is intended for standard ISO rhombic holders with matching seat and fastening.

Is this insert supplied with a chipbreaker or hole?
The DCLNR2020K comes without a chipbreaker and without a hole, allowing choice of holder and chip control strategy to suit the workpiece material and process.

Which materials can be machined with this insert?
The insert is a carbide grade designed for general turning tasks; the correct chipbreaker or grade should be selected according to the specific workpiece material and cutting conditions for optimal results.

How does the 7° relief and 55° lead angle affect cutting?
The specified relief and lead angles reduce flank contact and moderate cutting forces during engagement, improving surface finish and helping to preserve edge life under typical turning feeds and speeds.

What system components are recommended for reliable clamping?
A matched ISO holder or boring bar, the appropriate shim/clamp set and correct replacement screws are recommended to ensure stable clamping and repeatable positioning of the insert.
