PCLN R2020K PCLNR2020K ISO turning insert by Tungaloy — 7° clearance

The PCLNR2020K is an ISO‑standard turning insert designed for general external and internal turning, offering pentagonal indexing and a 7° clearance angle for stable machining.

• ISO-standard turning insert
• Pentagonal shape for multiple indexing
• Carbide construction for long tool life
• 7° clearance angle for stable machining

Stable performance for everyday turning operations

The ISO standard of this insert ensures predictable mounting and repeatable results across compatible holders. Designed for use in turning, the geometry and tolerance class support consistent contact conditions, which directly reduce vibration and improve surface finish. Selecting an insert with carbide construction means higher resistance to abrasion and thermal loading, enabling longer tool life and fewer interruptions in production. This results in a measurable effect on process efficiency and machining stability.

Geometry designed for quick indexing and process continuity

A pentagonal plate form provides up to five usable cutting edges, simplifying inventory and reducing tool change frequency. The 7° clearance angle combined with the 108° included angle offers a balance between edge strength and access to the workpiece, making the insert suitable for a range of straightforward turning tasks. The lack of a chipbreaker means the insert is best paired with an appropriate cutting grade and machining parameters tailored to the workpiece and the desired chip form.

Material choice and compatibility guidance

Manufactured from carbide, the insert delivers robust cutting performance under typical turning loads. Compatibility with a toolholder depends on form, clearance angle, tolerance class, clamping method, size and thickness; these factors should be matched to the holder specification. Where uncertainty exists about the correct grade or holder combination, selecting a matching grade and, if needed, a complementary chipbreaker geometry will optimise tool life and surface outcome.

Integration into the tooling system and practical use

The insert is supplied as a component of an ISO insert system and is intended for use with a suitable external holder or boring bar plus clamping set and replacement screws. Planning the system around the insert’s R2020K designation, thickness and pentagonal form simplifies procurement and tool management. For complex or specialised materials, consider adjusting feeds and speeds and pairing the insert with an appropriate cutting grade to maintain process security.

FAQ

What holders are compatible with this insert?
Compatibility depends on holder form, clearance angle, tolerance class, clamping method, size and thickness; the PCLNR2020K requires a holder designed for the R2020K geometry.

Does the insert include a chipbreaker?
No — the PCLNR2020K is supplied without a chipbreaker and should be paired with a cutting grade and machining parameters suited to the workpiece.

How many cutting edges are available per insert?
The pentagonal plate form provides up to five indexable edges, enabling multiple re‑uses before disposal.

What are the key dimensional values to check before ordering?
Check thickness (2.38 mm), clearance angle (7°), included angle (108°) and plate size (R2) to ensure compatibility.

For which applications is this insert intended?
The insert is intended for general external and internal turning within ISO insert systems; choose the cutting grade and parameters to match the workpiece material.
