PCLNL2020K PCLN L2020K carbide turning insert by Tungaloy — pentagonal, 108°

PCLNL2020K is an ISO‑standard carbide turning insert engineered for precise external and internal turning where reliable indexing and consistent cutting performance are required.

• ISO‑standard pentagonal shape for versatile indexing
• Carbide construction for durable cutting edges
• 7° clearance angle for controlled chip formation
• 108° included angle for robust external turning

Reliable, ISO‑compatible design for consistent production

The ISO-standard geometry of the insert ensures predictable seating and interchangeability across compliant tool holders, which simplifies tooling logistics and reduces setup time. Made from carbide, the grade provides a balance between wear resistance and toughness that supports repetitive turning cycles. The pentagonal shape allows multiple effective indexing positions, so the component life is extended before replacement, improving process economy without compromising reproducibility.

Geometry that improves stability and surface quality

A 108° included angle contributes to a solid cutting edge engagement, particularly beneficial for heavier cuts and shoulder turning where rigidity matters. Combined with the 7° clearance angle, this geometry helps to control chip flow and reduces rubbing behind the cutting edge, resulting in enhanced surface finish and lower tendency for built‑up edge. These characteristics make the insert suited to conventional and demanding turning tasks where dimensional accuracy and finish are priorities.

Straightforward compatibility and selection guidance

Compatibility with holders is defined by form, clearance angle, tolerance class, fastening style, size and thickness; selecting a matching holder ensures secure clamping and repeatable performance. The insert’s pentagonal form and indexing capability permit quick rotation to a fresh cutting edge, minimising downtime. For applications involving varied materials, choosing the appropriate chipbreaker and carbide grade tailored to the workpiece will optimise tool life and machining cost per part.

Practical system considerations for workshop use

The insert is intended for use within a system consisting of ISO turning inserts, a suitable external holder or boring bar, and required shim/fastening hardware. Absence of a mounting hole simplifies the clamping interface but necessitates compatible clamp geometries on the holder. Where finishing or high‑precision turning is required, pairing the insert with a high‑stability holder and appropriate cutting parameters will translate the insert’s geometry and carbide properties into consistent, measurable productivity gains.

FAQ

What applications is this insert suited for?
The PCLNL2020K turning insert from Tungaloy is designed for external and internal turning, offering reliable performance for general turning tasks and shoulder work.

How is the insert indexed and how many cutting edges are available?
The pentagonal geometry enables multiple indexing positions; the exact number of usable edges depends on the cutting conditions and applied wear criteria for the PCLNL2020K insert.

Which holder features are necessary for correct mounting?
Correct mounting requires a holder matching the insert’s form, 7° clearance angle, tolerance class, fastening style, size and thickness to ensure secure clamping and repeatable seating of the PCLNL2020K.

Does the insert include a chipbreaker or coating?
This designation is supplied without a chipbreaker; coating information is not provided in the data and should be confirmed if required for specific material machining.

Can this insert be used for hard or pre‑hardened steels?
The PCLNL2020K is a general ISO‑standard carbide insert; suitability for pre‑hardened steels depends on the carbide grade and recommended cutting parameters and should be validated for the specific hardness range and material.
