Pafana NNZC 2020 S20 NOZ TOK.ISO 2 R — cutting tool insert, ISO 2-sided, model ISO2R2020P20

Pafana NNZC 2020 S20 NOZ TOK.ISO 2 R is a two-sided replaceable cutting insert designed for turning operations in metalworking. The ISO two-sided configuration provides reversible cutting edges to extend service life and reduce tooling costs. This insert is intended for use in compatible external turning and profiling tool holders and is suitable for operations that require repeatable geometry and straightforward indexing.

Advantages

The two-sided ISO design offers a balance of economy and convenience by allowing quick index changes between edges without complex adjustments. The insert’s geometry is optimized for stable cutting during external turning, delivering consistent chip formation and predictable wear patterns. Reversible use reduces the number of inserts required for a given production run and simplifies inventory management.

Suitable for

• Precision external turning of shafts and cylindrical parts
• Profiling and contouring where repeatable edge geometry is needed
• General-purpose turning in a wide range of ferrous materials

Key specifications

• Insert type: two-sided reversible turning insert
• Geometry: ISO two-sided configuration designed for turning
• Mounting: compatible with ISO-type turning tool holders that accept two-sided inserts
• Primary application: external turning and profiling
• Economic feature: reversible edges for extended life and reduced tooling cost

How to use

Install the insert into a compatible ISO two-sided turning tool holder following the tool holder manufacturer’s clamping and torque specifications. Ensure the cutting edge orientation matches the intended right-hand or left-hand turning direction as required. Set appropriate cutting parameters — cutting speed, feed, and depth of cut — according to the workpiece material and insert geometry. Inspect the insert before use for proper seating and absence of damage; replace or re-index to the second edge when wear affects surface finish or dimensional accuracy.

Usage recommendations

Use coolant or flood lubrication where applicable to improve chip evacuation and extend insert life during prolonged or heavy cutting. For best results, follow the machine tool and tool holder manufacturer’s recommendations for clamping torque and insert seating. Monitor wear periodically and index the insert to the unused edge when cutting performance declines.
