How to Thread a Tap
A tap is a tool used to make female threads, in other words, a hole that is threaded on the sides for a screw, bolt or other implement to thread into. The tap tool consists of the tap itself (cylindrical piece of metal tapered at one end with threads) and the tap handle. Create the hole first, then insert the tap into the hole to create the thread. Use cutting oil to lubricate the threading process.
Instructions
- 1
Drill the correct diameter hole into the metal to the right depth that needs to be threaded.
2Wipe cutting oil around the taps thread. Place the end of the tap into the drilled hole at a 90-degree angle (perpendicular) to the surface of the hole. Push the tap and make a clockwise quarter turn before turning it counterclockwise to free the hole of metal chips.
3Turn the tap another clockwise quarter turn, before turning it counterclockwise again to remove the chips. Continue in this fashion until you thread the hole completely.
