Lathe Tool Insert Pafana NNPY A34 2516 S20 NOZ TOKARSKI

Pafana NNPY A34 2516 S20 NOZ TOKARSKI is a replaceable lathe tool insert designed for general turning operations on metal. The insert is intended to be mounted in compatible lathe tool holders and provides a predictable cutting edge for repetitive machining tasks. Its form factor and cutting geometry suit a range of conventional turning jobs in workshops and industrial production environments where a durable, easy-to-replace cutting tip is required.

Advantages

The design delivers consistent performance across medium-duty turning applications, offering repeatable dimensional accuracy and stable tool life when used with appropriate cutting parameters. As a replaceable insert it minimizes downtime for resharpening, simplifies tool setup, and supports efficient material removal. The insert’s standardized shape allows quick replacement and reliable seating in matching holders, reducing vibrations and improving surface finish compared with worn or improvised cutting edges.

Suitable for

• General external and internal turning of ferrous and non-ferrous metals
• Medium-duty finishing and semi-finishing passes on lathes
• Batch production where frequent insert changes are required
• Workshops and industrial turning operations that use indexable inserts

Key specifications

• Replaceable indexable insert for lathe turning
• Geometry suited for conventional turning and facing operations
• Compatible with matching tool holders designed for this insert family
• Durable cutting edge for medium-duty machining
• Standardized dimensions for predictable seating and alignment

How to use

Install the insert into a compatible lathe tool holder following the holder manufacturer’s instructions, ensuring correct seating and secure clamping. Set appropriate spindle speed, feed and depth of cut based on the workpiece material and the insert’s recommended cutting parameters. Begin with conservative cutting conditions and adjust to optimise surface finish and tool life. Monitor the cutting edge for wear and replace the insert when wear marks or chipping affect dimensional accuracy or finish quality.

Usage recommendations

Use coolant or appropriate cutting fluid for improved tool life and surface finish when machining tougher materials; maintain correct clamping torque on the holder to ensure repeatable positioning and minimise vibration.
