PCFN L2020- ISO turning indexable insert, pentagonal, Tungaloy

The PCFN L2020- is an ISO-standard pentagonal turning insert designed for external and internal turning, compatible with standard holders and clamp systems.

• ISO-standard pentagonal insert
• 7° clearance angle for flexible seating
• Carbide construction for wear resistance
• No central hole — clamp-compatible design

Consistent accuracy through ISO conformity and pentagonal design

The ISO designation ensures straightforward integration with a wide range of holders and boring bars, offering predictable positioning and repeatable results. The pentagonal shape provides multiple indexable cutting edges, which reduces tool change frequency and improves uptime. Made from carbide, the insert offers reliable wear resistance and stable performance across batch production, so the machining process remains steady and rework is minimised. The ISO labelling simplifies procurement and inventory management in a production environment.

Easy mechanical integration and fixture options

Compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness; the L2020- designation guides selection of the correct clamp or screw type. The insert is supplied without a central hole, making it suitable for modern clamp-style seats and common pocket designs. With a 7° clearance angle and a plate thickness of 2.38 mm, the component seats securely under standard clamping forces, helping to maintain cutting geometry and tool life when paired with a correctly matched holder and shim set.

Application range and machining considerations for turning

This series is intended for external and internal turning; when using the insert, select an appropriate chipbreaker and grade according to the workpiece material and cutting strategy, as the model itself is supplied without a chipbreaker. The insert’s geometry includes an 108° included angle and the size designation L2, which together influence toolpath planning and approach angles in turning operations. For light to medium turning tasks where multiple indexable edges are valued, the insert delivers economical edge usage and predictable finish quality.

Operational benefits, handling and economic impact

Using an indexable pentagonal insert reduces changeover time and lowers per-edge cost thanks to five available edges. The carbide substrate contributes to extended edge life, while the ISO conformity cuts complexity in tool management across different machines. Routine handling is straightforward: store blades protected from shocks, ensure correct seating in the pocket, and tighten clamps to the specified torque to preserve geometry. Overall, the design supports efficient production cycles and consistent output quality.

FAQ

What work is the PCFN L2020- best suited for?
The PCFN L2020- insert from Tungaloy is designed primarily for external and internal turning; its pentagonal form and ISO designation make it suitable for general turning tasks where multiple indexable edges are advantageous.

How does the absence of a central hole affect mounting?
Because the insert is supplied without a central hole, it is intended for clamp-style pockets; secure seating is achieved via the pocket geometry and clamp or screw assemblies compatible with the L2020- ISO form.

Which materials can be machined with this insert?
Selection of cutting grade and chipbreaker should follow the workpiece material; the PCFN L2020- blank is carbide and serves as a versatile basis when paired with an appropriate grade for steels, cast irons or non-ferrous alloys.

How many cutting edges are available per insert and what is the thickness?
The pentagonal geometry provides up to five indexable edges, and the plate thickness is 2.38 mm, supporting stable clamping and consistent edge presentation.
