SDQC L2020K SDQCL2020K Tungaloy turning insert — 90° square, 15° relief

SDQCL2020K is an ISO‑format indexable turning insert for external and internal turning, featuring a square geometry, 15° clearance and a cylindrical hole with double‑sided countersink.

• Carbide construction for stable tool life
• ISO L2020K format for broad compatibility
• 15° relief for secure cutting clearance
• Cylindrical hole with 70°–90° countersink

Precision and consistent results for general turning operations

The carbide composition delivers stable wear resistance and consistent performance during series production and short runs alike. As an ISO‑standard indexable insert, the component offers predictable tool life and repeatable geometry, supporting process reliability in turning. The 90° geometry provides full‑face contact for shoulder and profile turning, while the 15° relief prevents rubbing and reduces cutting forces. The SDQCL2020K is supplied without a chipbreaker, so selecting the correct chipformer or insert grade for the workpiece material is essential to achieve the intended surface finish and swarf control.

Compatibility and secure clamping across ISO holders

Compatibility with toolholders depends on form, clearance angle, tolerance class, fastening and insert dimensions; the ISO L2020K designation ensures straightforward matching to standard square‑insert holders. The 2.38 mm thickness and L2 size are decisive for stability under cutting loads and must be matched to the holder pocket and screw arrangement. The central cylindrical hole combined with the double‑sided countersink (70°–90°) permits reliable clamping using standard screws and clamping sets, reducing mounting time and ensuring repeatable positioning when inserts are indexed or replaced.

Geometry, material and application guidance in practice

The combination of carbide material, square plate form and the specified hole geometry makes this insert a versatile option for external and internal turning across a wide range of steels and non‑ferrous materials when the correct grade is chosen. The absence of an integrated chipbreaker means the insert is suited to operations where chip control is managed by toolpath, cutting parameters or an external chipformer. When machining interrupted cuts or heavy cross‑sections, the robust square form and 90° corner support help maintain dimensional stability and reduce deflection. For system setup, confirm holder compatibility by comparing form, 15° relief, pocket tolerance and insert thickness.

FAQ

What work is this insert designed for?
The SDQCL2020K insert is designed for general external and internal turning operations where a square, 90° geometry and 15° relief are advantageous.

Which materials can be machined with this insert?
As a carbide indexable insert, the SDQCL2020K performs well on a range of steels and common non‑ferrous materials when paired with the correct insert grade and cutting parameters.

How is the insert fastened in the holder?
The SDQCL2020K uses a central cylindrical hole with a double‑sided countersink (70°–90°) to permit secure clamping with standard screws and clamping sets in ISO holders.

Is there a chipbreaker on this insert?
This insert is supplied without a chipbreaker; chip control must be achieved via cutting conditions, toolpath strategy or a dedicated chipformer if required.

How to ensure holder compatibility for this insert?
Confirm holder pocket form, pocket angle, tolerance class, fastening method, insert thickness (2.38 mm) and L2 size; these determine whether the insert fits securely and performs as expected.
