3. OPERATION
3.1. CUTTING INTERNAL THREADS
3.1.1. To cut an internal thread through a solid piece of material, Drill a correctly sized hole using a tapping drill - refer to the char above
3.1.2. Ensure that the drilled hole is free from burrs and clear of swarf, apply a smear of suitable lubricant.
3.1.3. Select a tap of the correct size and required thread. Secure it in the tap wrench. Apply a smear of lubricant to the tip of the tap.
3.1.4. Place the tap in the hole and grasp the tap wrench with both hands. Apply even pressure and turn the tap clockwise until it begins to bite.
Ensure that the tap is kept square to the workpiece at all times.
3.1.5. Continue to turn the wrench until more resistance is felt (usually about ½ a turn) then give it a ¼ turn anti-clockwise until a slight click is
felt. This is the swarf from the clockwise twist being broken off.
3.1.6. Continue to repeat this action until the tap has run almost its complete length (ensure that a suitable lubricant is applied regularly).
To cut a thread in a blind hole, use the same instructions as above but take care not to jam the tap in the bottom of the hole.
