SDJCL2020K SDJC L2020K — Tungaloy ISO indexable turning insert (square L2, 15° relief)

The SDJCL2020K is an ISO‑compliant, square indexable turning insert designed for general turning operations, offering a 15° relief for secure engagement in both external and internal turning

• ISO‑standard square insert L2
• Cemented carbide for wear resistance
• 15° relief angle for secure cutting
• Cylindrical hole with double countersink

Stable, ISO‑compliant performance for turning operations

The ISO‑standard geometry ensures predictable fits with matching holders: compatibility depends on form, relief angle, tolerance class, fastening, size and thickness. Made from cemented carbide, this insert delivers a combination of toughness and wear resistance that supports steady metal removal rates. The square (L2) shape and 90° included angle make the component suitable for a wide range of routine facing and turning tasks, while the 15° relief angle reduces rubbing and helps maintain cutting-edge stability during interrupted cuts.

Clamping design and mechanical benefits that cut setup time

A precise clamping interface speeds tool changes and reduces vibration. The insert’s cylindrical hole with double countersink (70°–90°) provides secure location and consistent seating in matched holders and clamping kits, improving repeatability across indexings. With a plate thickness of 2.38 mm, rigidity is increased compared with thinner grades, which helps sustain surface finish quality at higher feeds. The insert is supplied without a chipbreaker, allowing selection of a chip control geometry and grade that best matches the workpiece material and machining strategy.

Practical selection guidance and system integration

For effective use, pair the insert with an appropriate external holder or boring bar sized for the L2020K designation and the square L2 format; include the correct shim and clamp set plus replacement fixing screws as part of the system. Choose a grade and chipformer according to workpiece properties and stability: the combination of cemented carbide and the 15° clearance is a strong starting point for medium‑duty turning. The model series is intended for general turning applications and integrates into standard ISO tool systems, making it straightforward to plan tool lists and spare inventories for production or jobbing environments.

FAQ

What holder features must be matched for correct fit? The SDJCL2020K requires a holder matching form, relief angle, tolerance class, fastening, size and thickness; ensure the toolholder accepts a square L2 insert and clamps into the cylindrical hole configuration.

Can this insert be used for both external and internal turning? Yes, the insert is designed for external and internal turning operations; selection of holder and approach angle should reflect the specific turning task.

Why is there no chipbreaker fitted to the insert? The insert is supplied without a chipbreaker so that a chip control geometry suitable for the workpiece and cutting parameters can be chosen to optimise chip flow and surface finish.

Which material is the insert made from and what does that mean for wear? The SDJCL2020K is produced from cemented carbide, offering a durable cutting edge and good resistance to abrasion for general turning tasks.

How does the hole and countersink design benefit clamping? The cylindrical hole with double countersink (70°–90°) ensures reliable seating and repeatable clamping force in compatible holders, which improves indexability and reduces the need for repeated adjustments
