Pafana NNZC 1616 S30 NOZ TOK.ISO 2 R — indexable lathe boring bar holder, ISO 1616 pattern

Pafana NNZC 1616 S30 NOZ TOK.ISO 2 R is an indexable lathe boring bar holder engineered for ISO-style tooling with a 1616 interface. The holder accepts interchangeable cutting inserts and secures them for internal turning and boring operations in turning centers and conventional lathes. Designed for medium-duty metalworking, it provides repeatable insert indexing and stable clamping to support consistent bore geometry and surface finish.

Advantages

The design of the Pafana NNZC 1616 S30 NOZ TOK.ISO 2 R delivers stable toolholding and straightforward insert replacement without extensive setup. Its ISO 1616 interface ensures compatibility with a wide range of ISO-format adapters and toolposts, while the indexable insert system reduces downtime by enabling quick indexing or replacement. The holder’s geometry promotes rigidity inside the bore, helping to minimize chatter and improve dimensional accuracy during internal turning.

Suitable for

• Internal turning and boring operations in lathes and turning centers
• Medium-duty metal cutting tasks on steels, cast irons and non-ferrous alloys
• Applications requiring repeatable insert indexing and frequent tool changes
• Workholding setups using ISO 1616 pattern toolposts and adapters

Key specifications

• Toolholder type: indexable boring bar holder for internal turning
• Interface pattern: ISO 1616 style mounting
• Shank size: 16 mm square shank compatible with 1616 toolholders
• Insert compatibility: accepts ISO-format interchangeable inserts for boring
• Clamping method: mechanical clamp for stable insert retention and indexing
• Intended machining duty: medium-duty internal turning and finishing

How to use

Mount the holder into a compatible toolpost or adapter with the ISO 1616 interface and secure the shank according to the machine’s setup procedure. Select an insert appropriate for the material and operation, seat it in the pocket, and tighten the clamp to the recommended torque to ensure stable retention. Set correct bore diameter, feed and speed parameters for the material and tool geometry, then perform test cuts to verify alignment and cutting conditions before production machining.

Usage recommendations

Use inserts rated for the workpiece material and maintain recommended clamping torque. For improved stability, support extended overhangs and reduce depth of cut when approaching machine or setup limits. Inspect insert seating and clamp condition regularly and replace worn or damaged components to preserve dimensional accuracy and surface finish.
