Pafana NNZC 1616 S20 NOZ TOK.ISO 2 R – Turning tool holder, boring/bar holder, ISO 2R

Pafana NNZC 1616 S20 NOZ TOK.ISO 2 R is a turning tool holder with a 16 x 16 mm square shank configured for ISO 2R indexable inserts. The S20 length variant provides a compact profile suitable for a variety of external turning, boring and facing operations. The holder is designed to clamp ISO-format inserts securely and to maintain repeatable positioning during machining, making it appropriate for workshop and production metalcutting tasks where stable tool seating and predictable tool geometry are required.

Advantages

The design offers stable clamping of ISO 2R inserts and consistent seating to support repeatable cutting performance. The compact 16 x 16 mm shank and S20 length reduce overhang and improve rigidity for external turning and light boring operations. The holder is compatible with common ISO indexable inserts, enabling quick insert changes and minimizing downtime. Its geometry supports accurate face and profile machining with predictable tool offset and straightforward mounting to standard tool posts.

Suitable for

• External turning of shafts and cylindrical parts
• Light boring and internal profiling where short overhang is beneficial
• Facing operations on lathes requiring ISO 2R inserts
• General workshop machining and small-series production

Key specifications

• Shank cross-section: 16 x 16 mm
• Length variant: S20 (short/compact overhang)
• Insert type: ISO 2R indexable inserts (right-hand orientation)
• Primary applications: external turning, boring, facing
• Clamping: mechanical clamping designed for repeatable seating of inserts

How to use

Mount the tool holder securely in the lathe tool post or turret using appropriate clamping hardware, ensuring the holder is aligned with the workpiece centerline. Install a compatible ISO 2R insert, tighten the clamping screw to the manufacturer's recommended torque and verify seating and orientation before cutting. Set cutting parameters (speed, feed, depth of cut) according to the insert grade, workpiece material and machining operation. Periodically check insert condition and re-tighten the clamping screw if required during extended use.

Usage recommendations

Use the holder with inserts and cutting parameters matched to the workpiece material; keep overhang minimal to maximize rigidity and part quality. Inspect clamping surfaces and the insert seat for wear, and replace inserts or the holder if seating accuracy degrades to preserve dimensional repeatability.
