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

A PCLNR2020K ISO-standard carbide insert engineered for external and internal turning, designed to fit holders matching form, clearance, tolerance and size

• ISO-standard carbide insert for turning
• Pentagonal shape with five cutting edges
• 7° clearance angle for stable cutting
• 2.38 mm thickness for precise seating

Greater process stability through ISO conformity and geometry

The ISO-standard format ensures straightforward integration into existing tool systems: form, clearance, tolerance class, fastening, size and thickness determine holder compatibility. The pentagonal geometry provides five indexed cutting edges, reducing downtime for insert changes and improving productivity in batch work. Built from carbide, the cutting tip sustains reliable performance under typical turning conditions, while the defined 7° clearance prevents rubbing and promotes consistent chip flow. This combination leads to fewer interventions and a more predictable machining cycle.

Clear technical advantages that simplify tool setup

Engineered thickness and profile translate directly into mounting accuracy and repeatability. The 2.38 mm plate thickness and the R2 corner specification give a precise seating interface and controlled nose radius for finishing and semi-finishing passes. Without a central hole, clamping relies on dedicated seat geometry; selecting the correct holder and clamping set is therefore essential. The insert’s 108° included angle supports stable cutting forces, which benefits both external and internal turning by reducing vibration and improving surface quality.

Practical selection guidance for material and process

Although this indexable insert is supplied without a chipbreaker, the choice of cutting edge geometry and carbide grade should match the workpiece material and operational stability. For roughing on less rigid setups, a more robust grade or a chip-control variant is recommended; for finishing on stable setups the pentagonal shape and fine nose radius support superior surface integrity. The system approach — insert, matching external holder or boring bar, shim/clamping set and spare screws — allows straightforward adaptation to existing toolholders without reengineering the setup.

Compatibility, inventory efficiency and shop-floor benefits

Adopting ISO-format inserts reduces inventory complexity: a single PCLNR2020K insert provides multiple usable edges and easy replacement when wear occurs. The standardised dimensions permit predictable tool life planning and faster changeovers, supporting lean manufacturing goals. Where process reliability matters, consistent seating and the measured 7° clearance minimise thermal and mechanical surprises, helping to preserve the cutting edge and maintain steady cycle times.

FAQ

What turning operations suit this insert?
The PCLNR2020K insert is intended for both external and internal turning; its pentagonal form and measured nose specification make it suitable for finishing and semi-finishing where ISO-format inserts are used.

How is holder compatibility determined?
Compatibility depends on form, clearance angle, tolerance class, fastening, size and thickness; matching these parameters to the insert’s specifications ensures correct seating and repeatable performance.

How many cutting edges are available per insert?
The pentagonal shape provides five indexed cutting edges, allowing multiple repositions before replacement is required.

Does the insert come with a chipbreaker?
This variant is supplied without a chipbreaker; chip control should be achieved through grade selection and matching cutting parameters or by choosing an alternative insert with an integrated breaker when needed.

Which material is the insert made from?
The insert is manufactured from carbide, chosen for wear resistance and dimensional stability in turning operations.
