Threading Tap FANAR Narzynka M2.5 N1-121001-0025 – metric M2.5 hand/ machine tap

FANAR Narzynka M2.5 is a metric M2.5 tapping tool designed for cutting and restoring internal threads of size M2.5. Supplied as model N1-121001-0025, this hand/machine tap is suitable for use in metal and other materials compatible with standard taps. It is intended for mechanical assembly, maintenance, repair and prototype work where small, precise internal threads are required.

Advantages

The FANAR Narzynka M2.5 provides consistent thread geometry for reliable fastening. It is compatible with both hand tapping and machine tapping setups, allowing flexible use in bench or workshop environments. The tool is manufactured to metric thread standards to ensure interchangeability with metric M2.5 fasteners and to deliver accurate, repeatable thread profiles for small-diameter applications.

Suitable for

• Cutting new M2.5 internal threads in metal components
• Restoring damaged or worn M2.5 threads during repair work
• Prototype and small-series mechanical assembly where M2.5 fasteners are used
• Hand tapping operations and machine tapping in light-duty machining

Key specifications

• Thread size: M2.5 (metric)
• Intended use: internal thread cutting and restoration
• Operation modes: hand tap and machine tap compatible
• Material compatibility: metals and materials suitable for standard metric taps
• Application areas: mechanical assembly, maintenance, repair, prototyping

How to use

Select an appropriate pilot hole sized for an M2.5 thread according to metric tap drill charts and secure the workpiece. For hand tapping, use a suitable tap wrench, align the tap square to the hole, apply steady pressure and turn clockwise to cut threads, backing off periodically to clear chips. For machine tapping, mount the tap in the appropriate holder or chuck, set correct spindle speed and feed, and use lubrication or cutting fluid recommended for the workpiece material. After cutting, clean any chips from the threads and inspect fit with an M2.5 screw or thread gauge.

Usage recommendations

Use cutting fluid on ferrous materials to reduce friction and prolong tool life. Start taps carefully to ensure correct alignment; incorrect entry can cause thread distortion or tap breakage. When restoring threads, assess the extent of damage before choosing between chase tapping and re-machining the hole.
