Tapping is a process for machining internal threads.

I. Tools

• Tap: The main tool, consisting of a cutting part and a calibration part, with different specifications and models.

• Lever: Used to clamp the tap and transmit torque.

II. Steps

• Drilling: First drill a hole slightly smaller than the tap thread diameter, and the depth is determined according to the required thread length.

• Select the tap: Select the appropriate tap according to the thread specifications.

•  Install the tap: Install the tap on the lever to ensure verticality.

• Tapping: Aim at the center of the hole, apply light pressure to allow the cutting part to enter, slowly rotate the lever and apply pressure.

• Thread cleaning: After tapping to depth, withdraw the tap and clean the thread chips.

III. Precautions

• Select the right tool to ensure reliable quality.

• Check the hardness and toughness of the material to avoid tapping on hard and brittle materials.

• The drilling diameter must be accurate.

• Keep the tap vertical and stable.

• Use appropriate pressure to avoid breaking the tap.

• Clean the tools regularly.

• Do not force the operation if there is too much resistance.
