Pafana NNWC 2020 SW7 NOZ TOK.ISO 11 — cutting tool/knurling insert, MPN NNWC2020SW7M

Pafana NNWC 2020 SW7 NOZ TOK.ISO 11 is a replaceable cutting and knurling insert designed for use on metalworking lathes and turning machines. The insert conforms to ISO tooling designation and is intended for controlled material removal and patterned surface formation. It is suitable for applications requiring repeatable geometry, precise finishing passes and reliable knurling results on cylindrical workpieces.

Advantages

The design provides stable seating and consistent contact with the workpiece, enabling uniform knurl patterns and accurate turning results. Manufactured to precision tolerances, the insert delivers repeatability across multiple cycles and reduces the need for frequent adjustments. Its replaceable format minimizes downtime during tool changes and allows for rapid restoration of cutting performance without regrinding.

Suitable for

• External turning operations on lathes
• Finishing passes to achieve dimensional accuracy
• Knurling or patterned surface formation on cylindrical parts
• Short- to medium-run production where repeatability is required

Key specifications

• Functional type: replaceable cutting and knurling insert suitable for lathe turning
• Geometry: ISO-conforming tooling shape for consistent seating and engagement
• Application: external turning, finishing and knurling on cylindrical workpieces
• Material compatibility: designed for common engineering metals used in turning operations
• Mounting: insert-style fastening for quick replacement on compatible tool holders

How to use

Install the insert into a compatible tool holder following the lathe manufacturer’s clamping and alignment instructions to ensure secure seating and correct orientation. Set cutting parameters (cutting speed, feed and depth of cut) appropriate for the workpiece material and the knurling or finishing objective. For knurling, apply light to moderate radial feed to press the pattern into the surface while maintaining steady spindle speed; for finishing turning, use fine feeds and shallow depths of cut to achieve the required surface finish and dimensional tolerances. Inspect the insert regularly and replace it when wear affects pattern quality or dimensional accuracy.

Usage recommendations

Select a compatible tool holder rated for ISO insert geometries and ensure securing screws are torqued to the manufacturer's specification. Use coolant or cutting fluid where appropriate for the workpiece material to manage heat and extend insert life. For best results, verify machine alignment and run a test cut when changing insert type or workpiece material.
