SDQC R2020K turning insert (SDQCR2020K) by Tungaloy — carbide, 15° clearance

The SDQCR2020K is an ISO‑standard square turning insert designed for general external and internal turning, offering a 15° clearance and an R2 nose radius for consistent edge engagement.

• ISO‑standard square insert R2020K
• Carbide body for reliable tool life
• 15° clearance angle for stable cutting
• Countersunk hole (70°–90°) for secure clamping

Productive, repeatable performance for daily turning operations

The insert is manufactured from carbide and produced to ISO dimensions, which ensures consistent cutting performance and interchangeability with ISO holders. The 15° clearance angle reduces rubbing on the flank and supports stable cutting conditions, while the R2 nose radius balances strength and surface finish. As an ISO turning insert, the component is suited to serial production where reproducibility and low downtime are priorities; reduced tool changes and predictable wear contribute to higher process efficiency and lower unit cost per part.

Secure clamping and predictable seating for repeatability

A cylindrical hole with a double‑sided countersink (70°–90°) provides a positive seat and reliable torque transmission to the clamping system, ensuring the cutting edge remains stable under load. The 2.38 mm thickness and square form give four indexable edges, which supports efficient tool utilisation and straightforward indexing. This variant is supplied without a chipbreaker, offering flexibility where chip control is managed by the holder geometry or process parameters; the absence of an integrated chipbreaker can benefit finishing passes or materials where an external chipformer is preferred.

Practical compatibility and selection guidance for toolmakers

Compatibility with a given holder is determined by the insert form, clearance angle, tolerance class, fastening method, size and thickness — all ISO‑governed parameters that simplify selection for workshop engineers. The insert is intended for external and internal turning and integrates into systems comprising an ISO insert, a matching external holder or boring bar, clamping set and replacement screws. For users less familiar with insert‑to‑holder matching, choosing the correct grade and chipformer (where required) will determine surface finish, tool life and cutting stability; these choices should be aligned with workpiece material and machining strategy.

FAQ

What applications is this insert best suited for?
The SDQCR2020K insert by Tungaloy is designed primarily for external and internal turning operations where ISO‑standard geometry and a 15° clearance support stable cutting and reproducible results.

Can the insert be used in any ISO holder?
Compatibility depends on holder form, clearance angle, tolerance class, fastening and thickness; the SDQCR2020K follows ISO dimensions to simplify matching with compliant holders.

Why is there no chipbreaker on this variant?
This variant is supplied without a chipbreaker to allow users to rely on holder geometry or process‑specific chip control; it is suitable for finishing operations or where an external chipformer is preferred.

How many cutting edges does the square insert provide?
The square form and 2.38 mm thickness allow multiple indexable edges, enabling efficient use of the carbide insert before replacement.
