PCLN R2020H ISO turning insert (pentagonal, 7° clearance) — Tungaloy

PCLNR2020H is an ISO-standard carbide turning insert designed for external and internal turning in industrial machining environments

• ISO-standard pentagonal insert
• 7° clearance angle for secure cutting
• Carbide grade for stable chip formation
• Compatible with ISO turning holders

Precision fit and reliable geometry for industrial turning

The ISO-standard design ensures repeatable seating and interchangeability across conventional turning systems. The pentagonal shape combines multiple usable edges with a compact footprint, while the 7° clearance angle reduces rubbing at the flank and improves surface finish. Manufactured from carbide, the insert offers enhanced wear resistance compared with high-speed steels, and the 2.38 mm plate thickness contributes to rigidity during modest to medium cutting forces. Compatibility depends on holder form, tolerance class, fastening and thickness—this standardised approach simplifies inventory and shortens set-up times.

Predictable chip behaviour and process security without a chipbreaker

This variant is supplied without a chipbreaker, so chip control depends on the chosen cutting data, workpiece material and holder geometry. For stable results, pair the insert with an appropriate external holder or boring bar and select feeds that promote short, curl-type chips. The lack of an integrated chipformer also offers flexibility: different chip control strategies or dedicated chipbreaking geometries can be applied depending on the workpiece. These characteristics support process reliability and repeatable tool change routines in production environments.

System advantages that speed up workshop workflows

As part of an ISO insert system, the component works in concert with a matching holder, shim/clamping set and replacement screws; this modularity reduces downtime and supports fast insert replacement. The R2 corner radius provides a balance between edge strength and fine surface finish, making the insert suitable for a wide range of turning tasks. Clear system composition—insert plus holder assembly—helps to standardise tooling across machines and contributes to predictable cycle times and consistent part quality.

Geometry choice for strength and application range

The insert presents a nominal included angle of 108°, delivering robust edge support for general turning operations. The relatively thin plate design at 2.38 mm keeps the insert compact while maintaining sufficient support for typical turning loads. The ISO designation R2020H simplifies selection and ensures the insert matches holders that accept that format. When selecting grade and holder combination, consider the workpiece material and cutting conditions to achieve the required life and surface integrity.

FAQ

What turning applications is this insert suited for?
The PCLNR2020H Tungaloy turning insert is intended for external and internal turning operations and performs well in general-purpose machining where a pentagonal, ISO-standard insert is suitable.

Does the insert include a chipbreaker?
This insert is supplied without a chipbreaker, so chip control for the Tungaloy ISO turning insert relies on holder choice, cutting data and workpiece material.

Which holders accept the R2020H designation?
Holders that conform to ISO standards for R2020H-format inserts will accept this PCLNR2020H insert; compatibility depends on form, clearance, tolerance class, fastening and thickness.

What benefits does the 7° clearance provide?
The 7° clearance angle reduces flank contact during cutting, improving surface finish and helping to prevent premature edge wear on the carbide insert.

Is the corner radius suitable for finishing work?
The R2 corner radius offers a compromise between edge strength and achievable surface finish, making the insert appropriate for medium-finish turning tasks.
