Pafana cutting nozzle NNGC 2012 S20 NOZ TOK.ISO 12 R – indexable insert holder, ISO12R insert size

Pafana NNGC 2012 S20 NOZ TOK.ISO 12 R is an indexable insert holder designed for turning and related metalworking operations that accept ISO12R-format inserts. The holder features a compact NNGC 2012 body with an S20 shank size, providing a rigid mounting platform for ISO12R inserts and enabling repeatable cutting geometry during insert changes. It is intended for use in lathe and milling toolposts where replaceable inserts are required for efficient tool management and predictable machining results.

Advantages

The design supports quick and secure insert replacement, reducing downtime during tool changes. Its compatibility with ISO12R-format inserts ensures broad availability of cutting grades and geometries. The S20 shank provides stable clamping and good vibration resistance for standard turning and finishing cuts. The construct maintains consistent insert positioning to preserve cutting accuracy across multiple insert swaps.

Suitable for

• External turning on lathes using ISO12R inserts
• Light to medium roughing and finishing operations
• General-purpose metal removal on steels, cast irons and non-ferrous alloys (with appropriate insert grade)
• Workshops requiring quick insert changes and standardised tooling

Key specifications

• Toolholder type: indexable insert holder for turning
• Insert format: ISO12R-compatible inserts
• Holder model: NNGC 2012 form factor with S20 shank
• Mounting: mechanical clamp/seat for replaceable inserts
• Application: lathe turning and related machining where ISO12R inserts are used

How to use

Mount the holder securely in the machine tool turret or toolpost using the S20 shank clamping system. Select an ISO12R insert with the appropriate geometry and grade for the workpiece material. Seat the insert into the pocket, tighten the clamp or fastening screw to the manufacturer's recommended torque, and verify correct insert alignment and rake/clearance orientation. Run initial cuts with conservative feeds and depths to confirm setup and make incremental adjustments to cutting parameters based on material and insert grade.

Usage recommendations

Use inserts matched to the workpiece material and machining operation; ensure fastening hardware is torqued to the correct specification and inspect the seat and clamp for burrs or debris before each insert change. For best life and surface finish, monitor cutting conditions and replace inserts at the first sign of edge wear or chipping.
