Cutting Tool Holder Pafana NNZC 2525 M20 NOZ TOK.ISO 2 R

Pafana NNZC 2525 M20 NOZ TOK.ISO 2 R is a metalworking turning tool holder engineered for ISO-style indexable inserts. With a 25 x 25 mm square shank and an M20 clamping interface according to the manufacturer's naming, this holder provides a stable platform for external turning on CNC lathes. The design places the insert at the correct orientation for ISO-compatible cutting geometries and aims to deliver repeatable positioning and secure insert clamping during typical turning cycles.

Advantages

This tool holder offers rigid support for ISO indexable inserts and a compact 25 x 25 mm shank suited to standard lathe tool posts. The M20-style connection ensures consistent clamping alignment, reducing indexing errors and play. The construction is intended to minimize vibration transfer to the insert, helping to maintain surface finish and tool life under normal turning conditions. Compatibility with ISO insert geometries simplifies tooling selection and replacement.

Suitable for

• External turning operations on CNC and manual lathes
• Turning of steel, cast iron and non-ferrous materials with appropriate inserts
• Applications requiring ISO-style indexable inserts and repeatable insert positioning

Key specifications

• Shank size: 25 x 25 mm square
• Mounting/clamping interface: M20-style connection per manufacturer naming
• Insert style compatibility: ISO indexable inserts
• Orientation: R (right-hand) turning configuration
• Intended use: external turning / facing

How to use

Install the tool holder in the lathe tool post or turret with appropriate clamping torque for a 25 x 25 mm shank, ensuring the holder is seated squarely and the M20 connection (where applicable) is fully engaged. Fit a compatible ISO indexable insert and secure it according to the insert clamping mechanism specifications. Verify insert overhang and clearance to avoid interference with workholding or chuck components. Set cutting parameters (speed, feed, depth of cut) based on workpiece material and chosen insert grade, and perform a short test cut to confirm correct orientation and chip flow before full production.

Usage recommendations

Use inserts and grades suitable for the specific workpiece material and turning operation; verify clamping torque and seating each time the insert is changed. Regularly inspect the holder for wear, secure mounting, and absence of vibration or looseness to maintain consistent machining results.
