Difficulty Level

Tools/Supplies Needed:

• drill bit set
• tap set
• lubricating/cutting oil
• drill press
• hammer
• center punch
• clamps
• safety glasses

Procedure:

• ensure that the object you are working with is clean
• ensure that the tap you are using is clean
• mark out where you would like the threaded hole, then using a center punch and a hammer mark the center of the hole
• the center punch marks the center of the hole and will reduce the risk of the drill bit wandering
• using a drill and tap index, determine what size drill bit is required for the hole
• the drill bit must be smaller than the tap size
• clamp the object down to ensure it doesn't move while also reducing the risk of a safety hazard
• use cutting oil if needed when drilling the hole
• clean the hole before getting ready to tap threads
• apply cutting oil to the tap and hole
• ensure the newly drilled hole and tap is lined up correctly
• don't use the drill press' power for this procedure
• slowly feed the tap down to the object and turn the drill chuck by hand
• apply cutting oil when needed
• feed the tap all the way in the hole, then loosen the chuck and allow the chuck to be removed from the tap
• remove the tap by hand
• clean any cut material away from the hole
• clean tap when done before putting away

Frequently Asked Questions (FAQ):

How much pressure should I apply?

Apply medium pressure. Too little pressure and the tap won't start, too much and the threads will be damaged or you do risk breaking the tap.
