PCLN L2020H PCLNL2020H – Tungaloy indexable turning insert for ISO turning

A PCLNL2020H indexable insert designed for ISO‑standard external and internal turning, featuring a pentagonal form and a 7° relief angle for stable engagement

• ISO‑standard geometry for reliable fit
• Pentagonal form for five cutting edges
• 7° relief angle for precise engagement
• Durable carbide for longer tool life

Steady cutting performance and predictable wear

The indexable insert is manufactured in carbide, delivering a balance of toughness and wear resistance suited to serial and general turning tasks. The pentagonal geometry enables multiple usable edges, which reduces changeover frequency and supports continuous production. With a 108° approach angle the design favours robust cutting conditions and improved stability during heavy radial engagement. This combination of geometry and material yields consistent tool life and lower per‑part tooling cost in repetitive operations.

Secure mounting and clear holder selection criteria

Compatibility with the toolholder is defined by geometry factors: form, clearance angle, tolerance class, fastening, size and thickness. The insert has a 7° relief and a thickness of 2.38 mm, and is supplied without hole, so the matching seat and clamping kit must accommodate a pentagonal, holeless plate of size L2. The ISO designation L2020H simplifies selection of a compatible external holder or boring bar. For best results, pair the insert with a holder appropriate to the intended material, machining stability and the chosen chipbreaker or grade.

Cost efficiency through indexable design and material versatility

Using a replaceable plate reduces downtime and material waste: each pentagonal insert offers up to five cutting edges before replacement, improving throughput and lowering tooling expenditure. The carbide substrate withstands a broad range of workpiece materials when combined with an appropriate grade and chip control solution. For routine external or internal turning tasks the insert provides a pragmatic trade‑off between cutting life and edge robustness, supporting both finishing and medium‑duty roughing when process parameters are set according to stability and feed requirements.

FAQ

What materials can this insert machine?
The insert is a carbide ISO turning plate intended for general turning; material choice for machining depends on the selected grade and chipcontrol solution matched to the workpiece.

How is the insert fixed to a toolholder?
Mounting depends on the holder geometry and clamping set; the PCLNL2020H is a pentagonal, holeless plate and requires a seat and clamping kit compatible with size L2 and the 2.38 mm thickness.

How many cutting edges are available per insert?
Due to its pentagonal form, the plate provides multiple usable edges, allowing several index operations before replacement and reducing total tooling changes.

Is a chipbreaker included?
This version is supplied without a chipbreaker; for chip control, select an appropriate breaker type and grade for the intended material and cutting conditions.

Which code identifies this insert for ordering?
Order using the manufacturer article number 6844377 or the manufacturer SKU TUN6844377 for the Tungaloy PCLNL2020H insert.
