Threading Tap FANAR Narzynka M20 N2-188001-0200

FANAR Narzynka M20 is a threading tap designed to cut or restore internal metric threads sized M20. Produced by FANAR for metalworking and maintenance environments, this tool is intended for both manual and machine tapping applications where accurate M20 internal threads are required. The tap is suitable for use in production, repair and assembly tasks that demand consistent thread form and fit.

Advantages

The FANAR Narzynka M20 provides precise thread geometry and is produced to meet industry tolerances for metric threads. Its design supports reliable chip evacuation and consistent thread engagement, reducing the risk of damaged threads during cutting or restoration. The tap is compatible with standard tapping procedures and can be used with hand taps or power tapping equipment, offering flexibility across different workshop setups.

Suitable for

• Cutting new M20 internal threads in metal components
• Restoring worn or damaged M20 threads during repair work
• Machine or manual tapping in production and assembly processes
• Maintenance tasks requiring precise metric thread replacement

Key specifications

• Thread size: M20 (metric internal thread)
• Intended use: cutting and restoring internal threads
• Application: manual or machine tapping
• Material compatibility: suitable for common industrial metals (steel, cast iron, non-ferrous alloys) when used with appropriate cutting parameters
• Typical form: standard metric thread profile suitable for general engineering applications

How to use

Secure the workpiece firmly in a vise or fixture to prevent movement during tapping. Select appropriate cutting fluid and apply it to the hole and tap to reduce friction and improve chip evacuation. For machine tapping, set correct spindle speed and feed consistent with M20 thread cutting recommendations for the material. For manual tapping, align the tap square to the hole axis and advance with steady, even turns, reversing periodically to break chips. After cutting, clean the thread and inspect with a gauge or mating bolt to verify fit and alignment.

Usage recommendations

Match tap selection and cutting parameters to the workpiece material and hole preparation. Use correct tap drill size for M20 cores, maintain adequate lubrication, and avoid excessive torque to prolong tool life and ensure accurate threads. When restoring damaged threads, assess the extent of wear before tapping to determine if a repair insert or alternative method is required.
