Thread tap Wera Einschnittgewindebohrer M3 — metric hand tap for M3 threads

Wera Einschnittgewindebohrer M3 is a metric hand tap designed to cut and repair internal M3 threads. Produced by Wera, this tap is intended for precise thread cutting in metal and other suitable materials. It is shaped for manual use with a tap wrench or holder and is suitable for tasks where accurate M3 internal threads are required for assembly, repair, or prototyping.

Advantages

The Wera Einschnittgewindebohrer M3 provides consistent thread geometry and reliable fit for M3 fasteners. Its hand-tap design enables controlled material removal and tactile feedback during cutting, which helps reduce the risk of cross-threading. The tool is compact and simple to use with standard tap wrenches, making it suitable for bench work and field repairs. Material selection and manufacturing precision support repeatable performance for small-series and single-part operations.

Suitable for

• Cutting new internal M3 threads in metal components
• Repairing damaged or worn M3 threads
• Prototyping and small-batch mechanical assembly
• Maintenance tasks requiring manual tapping on-site

Key specifications

• Thread size: M3 (metric)
• Thread type: internal hand tap for standard metric threads
• Intended use: manual tapping with a tap wrench or holder
• Suitable materials: metals and machinable non-ferrous materials compatible with hand tapping
• Form factor: single-piece hand tap designed for one-handed tool holders or tap wrenches

How to use

Secure the workpiece firmly and ensure the hole is drilled to the correct diameter for an M3 thread. Mount the Wera hand tap straight in a compatible tap wrench or holder. Apply appropriate cutting lubricant where recommended for the work material. Begin cutting with steady, even pressure and rotate the tap forward several turns, then back off slightly to break chips and clear debris. Continue this cycle until the full thread depth is achieved, then reverse the tap to remove it from the hole. Inspect the thread with an M3 screw or a gauge to confirm fit and alignment.

Usage recommendations

Use the Wera hand tap with the correct drill pilot size and appropriate cutting lubricant for the material to extend tool life and improve thread quality. For hardened or abrasive materials, consider a suitable tapping method and check compatibility before use. Store the tap in a dry place and protect the cutting edges from impact to maintain performance.
