Take advantage of the combination of ISO-standard geometry, a pentagonal R2 form and a carbide construction for consistent, productive turning; the insert suits holders matched by form, clearance, tolerance class, fixation, size and thickness. Order the PCFNR2020- Tungaloy insert directly via Metav Werkzeuge or ask our consultants if needed.

PCFNR2020- (PCFN R2020-) Tungaloy turning insert — pentagonal R2, 7° clearance, carbide

A PCFNR2020- indexable carbide turning insert designed for ISO-standard external and internal turning, compatible with holders that match form, clearance, tolerance, fixation, size and thickness.

• ISO-standard indexable insert
• Pentagonal R2 geometry for versatility
• 7° clearance angle for controlled cutting
• Carbide grade for stable chip formation

Engineered for consistent, high‑throughput turning

The insert has been manufactured to the ISO-standard system, ensuring predictable fit and repeatability when paired with an appropriate holder. The pentagonal geometry provides multiple useful cutting edges while the moderate 7° clearance reduces rubbing on the flank, improving surface finish and tool life. Constructed from carbide, the component supports steady cutting forces and contributes to stable chip formation in routine turning operations. This section focuses on measurable performance aspects and setup compatibility to support efficient production planning.

Better surface quality and increased durability on typical turning tasks

With its moderate nose form and material choice, the insert is aimed at delivering improved surface quality and longer service intervals compared with unoptimised alternatives. The solid carbide body supports a robust cutting edge geometry, delivering wear resistance and repeatable performance under standard cutting parameters. For best results, select a chipbreaker and grade appropriate to the workpiece material and machining stability; although this geometry comes without a chipbreaker, matching a suitable grade will preserve tool life and machining economy.

Seamless system integration and straightforward handling

The insert integrates into a conventional ISO turning system: indexable plate, matching external holder or boring bar, plus a clamp set and spare screws where required. Compatibility is determined by form, free angle, tolerance class, fixation, size and thickness—note the R2 size, 2.38 mm plate thickness and 108° principal angle when checking holder fit. The insert is supplied without a hole, simplifying clamping options for many holders. Clear identification of these parameters reduces setup time and helps maintain stable process control across batches.

FAQ

Which materials can be machined with this insert?
The PCFNR2020- Tungaloy turning insert is a carbide grade intended for general turning; material suitability depends on the chosen grade and chipbreaker combination rather than the plate form alone.

How is holder compatibility ensured for this insert?
Compatibility requires matching the holder to the insert form, 7° free clearance, tolerance class, fixation method, plate size R2 and thickness 2.38 mm; check holder specifications against these parameters.

Does this insert include a chipbreaker?
The supplied plate is specified without a chipbreaker; select an appropriate chipbreaker style and grade in the system or choose a matching insert variant if chip control for specific materials is required.

What are the key dimensions to check before mounting?
Verify the plate form (pentagonal), plate size R2, thickness 2.38 mm, free clearance 7° and principal angle 108° to ensure correct fit and secure clamping.
