• internal UN 1.3/8 x 8 thread production or careful reworking where the existing component defines the thread
• The double ended design combines starting and finishing work in one compact hand driven tool.
• Form C geometry for blind hole focused internal thread work where this form is specified by the product data
• workshop, maintenance, assembly, and repair tasks with controlled manual tool guidance
• Process: manual driving or assisted driving depending on your holder and machine setup
• Use: thread cutting, re tapping, and thread cleaning depending on condition

Note Match thread system, size, pitch, tap stage, holder, and hole preparation before use.

• HSS-G cutting material supports precise hand thread cutting when the tool is aligned and lubricated correctly
• WN product execution gives a defined tool form for selection by standard and thread designation
• tolerance class 2B provides a clear selection reference for the intended internal thread
• double ended HexTap DS construction combines two working ends in a compact tool for service use
• Multi-Drive handling allows flexible driving with a suitable holder or drive tool

• The tool must match the exact thread system, size, pitch, and stage; choose another product in the Threading tools category when one of these criteria differs.

1. Confirm that the workpiece requires UN 1.3/8 x 8 and that the mating part uses the same thread system.
2. Prepare the hole and secure the workpiece so the tap can enter square to the surface.
3. Position the active end of the double ended tap square to the prepared hole.
4. Apply suitable cutting oil and start with steady hand pressure.
5. Turn the tool carefully and clear chips regularly without forcing the cutting edges.
6. Use the second end only when the thread stage and access situation require it.
7. Clean the thread and check fit with the mating part or a suitable inspection method.
