PDJN R2020K indexable insert for turning — pentagonal, 15° relief — Tungaloy

PDJNR2020K is a pentagonal, ISO-standard indexable insert designed for general external and internal turning operations, offering a 15° relief angle and a robust cemented carbide construction for reliable tool life and consistent machining results.

• Pentagonal insert for stable clamping
• 15° relief angle for versatile turning
• 2.38 mm thickness for secure seating
• Cemented carbide for long tool life

Precision and compatibility for consistent turning results

The PDJNR2020K insert is engineered as an ISO-compliant turning plate that fits into common external holders or boring bars when the form, relief angle, tolerance class, fastening method, size and thickness are matched. The 2.38 mm plate thickness and pentagonal shape enable a compact seat that reduces chatter and improves repeatability in batch production. Where a secure clamp is required, the absence of a central hole implies reliance on a matching seat and clamping set; this design promotes rigidity and simple indexability for multi-edge use.

What the geometry means for process efficiency

A 15° relief angle combined with a pentagonal outline and an included angle of 108° gives a balanced cutting geometry that suits a broad range of turning tasks. The indicated plate size R2 refers to the nose radius, which supports medium-accuracy finishes while allowing stable cutting forces. Because the insert is supplied without a chipbreaker, selection of cutting parameters and appropriate chip control elements in the toolholder becomes important; this flexibility allows optimisation for different materials and cutting modes, improving throughput and lowering tool-change frequency.

System approach: mounting, tooling and practical benefits

The insert is intended for use within a complete ISO insert system — compatible external holders or boring bars, a shim/clamping set and replacement screws form the typical kit. Choosing the correct combination ensures the cemented carbide body delivers good edge life under stable cutting conditions and supports predictable surface quality. The ISO series format simplifies inventory management: a single insert geometry can be rotated through multiple edges, reducing downtime and enhancing overall process economy in production environments.

FAQ

What holders are compatible with this insert?
Compatibility depends on matching the insert form and dimensions; the PDJNR2020K (Tungaloy, SKU 6755204-Tungaloy) fits ISO-configured external holders or boring bars designed for pentagonal inserts and the specified thickness.

Does the insert include a chipbreaker?
No, this insert is supplied without a chipbreaker; the absence allows adaptation of chip control via holder geometry or by selecting an appropriate chip control element for the operation when using the PDJNR2020K.

How many effective cutting edges are available per insert?
The pentagonal form provides multiple indexable edges; the exact number of usable edges depends on the clamping method and the chosen seating orientation when installing the PDJNR2020K insert.

Is the insert suitable for internal turning?
Yes; the PDJNR2020K is suitable for both external and internal turning when used with an appropriately sized boring bar or internal holder and the correct clamping components.

What is the function of the 15° relief angle?
The 15° relief angle reduces rubbing behind the cutting edge and supports general-purpose turning; it helps to balance cutting forces and contributes to consistent surface quality with the cemented carbide composition.
