PCLN R2020K — PCLNR2020K pentagonal indexable turning insert, 7° clearance — Tungaloy

PCLNR2020K is an ISO‑standard pentagonal indexable insert designed for external and internal turning operations where multi‑edge economy and consistent cutting geometry are required.

• ISO‑standard pentagonal insert, PCLN R2020K
• 7° clearance angle for controlled cutting
• 2.38 mm plate thickness, compact design
• Cemented carbide for consistent wear resistance

Consistent geometry for uninterrupted turning productivity

The pentagonal shape provides five usable cutting edges, offering cost‑effective indexing and predictable edge repeatability. With an included angle of 108° and a 7° clearance angle, the geometry supports stable cutting forces and repeatable contact conditions in both light and medium turning cuts. Manufactured in cemented carbide, this insert gives a balance of wear resistance and toughness that helps to maintain surface finish and dimensional accuracy over longer tool life. The compact 2.38 mm plate thickness contributes to rigidity in the clamping zone while keeping cutting forces controlled.

Compatibility guidance reduces setup risk

Compatibility with the toolholder is determined by insert form, clearance angle, tolerance class, fastening method, size and thickness; matching these parameters avoids misfits and ensures secure clamping. Select the appropriate chipbreaker style and grade to suit the workpiece material and machining stability — since this variant is supplied without a chipbreaker and without a hole, it is optimised for holders that clamp a full face and for applications where custom chip control is managed by the tool system. Clear reference to holder geometry and tolerance class simplifies selection and reduces set‑up time, improving overall process reliability.

Practical advantages: fewer tool changes, stable results

Using a multi‑edge pentagonal insert reduces tooling expenditure per cutting edge and decreases machine downtime for tool changes. The R2 size and balanced dimensions of this design permit efficient stock removal in turning and boring tasks while maintaining consistent edge engagement. In hands‑on production, the absence of a central hole simplifies seating in certain clamping systems and can improve rigidity under specific clamping arrangements. The result is repeatable component tolerances and reliable surface finishes across batch production.

System thinking for easier inventory and maintenance

This insert is part of an ISO insert system that includes the matching external holder or boring bar, shim/clamp set and replacement screws; planning the tool system as a whole streamlines spare‑parts management and reduces machine downtime. When stocking inserts, consider the grade and chipbreaker variants for each material class to limit complicated inventories. The combination of standardised interface geometry and a cemented carbide grade encourages consistent results across shifts and machines, supporting predictable process planning and cost control.

FAQ

What machining tasks is this insert suited for?
The insert is designed primarily for external and internal turning; the ISO pentagonal geometry supports routine turning operations where multi‑edge economy is beneficial.

How does compatibility with holders work for this insert?
Compatibility depends on insert form, clearance angle, tolerance class, fastening, size and thickness; verify holder specifications match the insert’s 7° clearance and 2.38 mm thickness before mounting.

Is a chipbreaker included with this insert?
This variant is supplied without a chipbreaker; select a holder or an alternative insert grade with an integrated chipbreaker when specific chip control is required.

How many cutting edges are available per insert and what is the benefit?
The pentagonal form provides up to five cutting edges, allowing economical indexing and reduced tooling costs while maintaining consistent cutting geometry.

What is the manufacturer SKU and who makes this insert?
The insert is produced by Tungaloy and is listed under manufacturer SKU TUN6755198 for identification in ordering and inventory.
