DDJNR2020K DDJN R2020K turning insert — Tungaloy, 15° clearance

DDJNR2020K is an ISO-formatted carbide turning insert designed for external and internal turning applications, offering standardised fitment and predictable tool behaviour in ISO clamping systems.

• ISO-standard rhombic insert R2
• Carbide body for stable cutting
• 15° clearance angle for precise geometry
• 2.38 mm plate thickness, no hole

Consistent positioning and cutting geometry for repeatable results

The insert is manufactured to ISO-standard dimensions so compatibility with ISO holders is reliable: positioning, tolerance class and fastening are standardised to ensure the cutting edge sits correctly every time. The 15° clearance angle maintains the intended rake and clearance geometry, reducing unwanted contact with the workpiece and improving process stability. For production environments that demand repeatability, a standardised insert form reduces setup variance and shortens changeover times.

Material choice that balances performance and wear resistance

Made from carbide, the insert offers high hardness and thermal resistance for aggressive turning operations while providing predictable wear behaviour. The moderate 2.38 mm plate thickness contributes to edge rigidity without excessive mass, supporting both finishing and light roughing tasks when matched with a suitable grade and chipformer. Selecting an appropriate carbide grade and chipbreaker tailored to the workpiece material will result in better surface quality and longer tool life.

Straightforward integration into ISO turning systems

The system design follows ISO conventions: the insert form, clearance angle, tolerance class, fixing method, size and thickness determine compatibility with toolholders. Because the insert uses a rhombic R2 format and is supplied without a hole and without a chipbreaker, it pairs with a range of external holders or boring bars that accept this geometry. This makes retrofitting into existing tool inventories simple and minimizes the need for new holder investment.

Application guidance and process optimisation

The insert is suitable for turning operations where a rhombic edge form is advantageous; typical tasks include external profiling and internal turning where a compact corner radius is required. Note that this variant has no chipbreaker, so choosing the right chipformer or an alternative grade will be essential when machining ductile or long-chipping materials. For process advice on grade selection, coolant strategy or recommended cutting parameters, specialist consultation is available to align insert selection with productivity and surface finish targets.

FAQ

What materials can be machined with this insert? The DDJNR2020K is a carbide turning insert suitable for a wide range of materials; selecting the correct carbide grade and chipformer will determine optimal performance for aluminium, steel or other alloys.

Does the insert require a specific holder type? Compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness; the rhombic R2 form fits standard ISO holders designed for this geometry.

Is there a chipbreaker included on the insert? This variant is supplied without a chipbreaker; a separate chipformer or a different grade with integrated chip control should be selected for materials prone to long chips.

What does R2020K indicate? R2020K is the ISO-related code for the insert form and tolerance family; it clarifies the insert’s geometry and ensures matching with ISO-compliant holders.

What support is available for selecting the right grade and cutting data? Technical guidance on grade selection, chip control and cutting parameters is available; Metav Werkzeuge can advise on matching the DDJNR2020K to specific workpiece materials and machining tasks.
