Application

This 2 piece hand tap set according to DIN 2181 made from HSS-G is used for internal BSF 7/8 x 11 threads in manual thread production, thread reworking, and workshop repair tasks. Select this product when the thread system, size, pitch, and tap stage match the drawing or the existing mating part.

The set supports staged manual internal thread production with two separate tapping stages. BSF designates a British Standard Fine thread used on inch based fastening points with a finer thread series. Before use, check alignment, holder fit, cutting oil, and the condition of the pre drilled hole so the thread profile can be produced without forcing the tool.

Application

  • internal BSF 7/8 x 11 thread production or careful reworking where the existing component defines the thread
  • The set supports staged manual internal thread production with two separate tapping stages.
  • staged manual tapping where separate tap stages are used in sequence
  • 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.

Benefits

  • HSS-G cutting material supports precise hand thread cutting when the tool is aligned and lubricated correctly
  • DIN 2181 product execution gives a defined tool form for selection by standard and thread designation
  • tolerance class medium provides a clear selection reference for the intended internal thread
  • separate tap stages support progressive manual cutting instead of forcing one tool to remove all material
  • set structure keeps the required hand tap stages together for the same thread designation
Drawbacks
  • 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.

Step by step

  1. Confirm that the workpiece requires BSF 7/8 x 11 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. Select the first tap stage from the set for starting the internal thread.
  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. Continue with the next tap stage until the thread profile is complete.
  7. Clean the thread and check fit with the mating part or a suitable inspection method.

Frequently asked questions (FAQ)

Question: Which thread does this product cover?

Answer: This product covers BSF 7/8 x 11. BSF designates a British Standard Fine thread used on inch based fastening points with a finer thread series.

Question: Is this product for internal or external threads?

Answer: This product is for internal threads. Use an external threading tool such as a round die when the workpiece needs an external thread.

Question: How do you choose the correct hand tap stage?

Answer: Choose the stage by the process step. The set supports staged manual internal thread production with two separate tapping stages.

Question: What should you check before ordering?

Answer: Check thread system, size, pitch, standard, tap stage, and holder fit against the drawing or the existing part.

Question: Where can you find technical background for hand taps?

Answer: Use the Technical information hand taps as PDF.

Question: Can this product be used for thread repair work?

Answer: Use it only when the existing internal thread matches the same thread designation and the thread condition still allows controlled re tapping or cleaning.

Question: Where can you find the threading tool catalog?

Answer: Use the VD 23 catalog as PDF.
