PCLN L2020- PCLNL2020- ISO pentagonal turning insert for turning (Tungaloy)

The PCLNL2020- is an ISO‑standard pentagonal indexable insert designed for external and internal turning, providing a compact geometry and reliable clamping compatibility for a wide range of holder systems.

*ISO indexable insert, pentagonal form L2
*7° clearance angle for versatile turning
*Carbide grade with 2.38 mm thickness
*No mounting hole, clamp‑style fixation required

Consistent compatibility with common holder systems

The model is built to ISO standards, so compatibility relies on matching insert form, clearance angle, tolerance class, fixation method, size and thickness to the selected holder. As an ISO‑compliant pentagonal insert, it fits most clamp‑style external holders and boring bars when the part geometry and clamping method align. This standardised approach reduces setup uncertainty and supports predictable tool replacement cycles, enabling smoother process planning and shorter downtimes.

Stable cutting geometry for reliable turning results

The pentagonal form, combined with a 7° clearance and carbide construction, prioritises rigidity during cutting. The absence of an integrated chipbreaker means that cutting performance depends on selecting an appropriate chipbreaker and grade for the workpiece and operation type; this design offers flexibility for custom chip control strategies while ensuring a stable cutting edge for finishing or semi‑finishing cuts. The robust geometry helps maintain surface quality and repeatable dimensional results.

Efficient edge economy and straightforward handling

A pentagonal insert provides multiple indexable cutting edges, which improves cost efficiency through edge rotation rather than full replacement. With an insert thickness of 2.38 mm, the component offers sufficient stiffness for typical turning tasks while keeping the cutter body profile compact. The lack of a central hole requires clamp fixation, which simplifies spare part handling by avoiding additional fasteners but necessitates compatible clamping kits and spare screws in the tool inventory.

Practical system setup and selection guidance

Use the insert as part of a system comprising an ISO insert, a matching external holder or boring bar, an appropriate clamping pad or clamp kit, and spare fastening screws. When specifying tools, consider the workpiece material, intended cutting parameters and machine stability; select a matching chipbreaker and carbide grade to suit the machining task. Clear documentation of holder geometry and tolerance class will ensure fast interchangeability and repeatable performance across production batches.

FAQ

What is the primary application for this insert?
The insert is intended for turning operations; the PCLNL2020- is suitable for both external and internal turning when used with compatible holders.

How does the pentagonal form affect tool life?
The pentagonal form offers multiple indexable cutting edges, allowing rotation to fresh edges and extending overall consumable life for the PCLNL2020- insert.

Is a central mounting hole required for this insert?
No; this insert is supplied without a mounting hole and therefore requires clamp‑style fixation in a compatible holder.

Which parameters determine compatibility with a holder?
Compatibility is determined by insert form, clearance angle, tolerance class, fixation method, size and thickness as specified for the ISO system
