OPERATION
CUTTING INTERNAL THREADS
-
To cut an internal thread through a solid piece of material, Drill a correctly sized hole using a tapping drill – refer to the chart above
-
Ensure that the drilled hole is free from burrs and clear of swarf, apply a smear of suitable lubricant.
-
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.
-
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. -
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.
-
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.
CUTTING EXTERNAL THREADS
-
Bevel the end of the workpiece to be threaded in order to make starting easier and apply a smear of lubricant to it.
Note: the width of the workpiece should ideally be 0.125mm to 0.025mm undersize of the die. -
Select a die of the correct size and required thread, and apply a smear of lubricant to it.
-
Insert the die into the die stock, place the chamfered threads side opposite to the lip of the die stock, and turn the set screws, fitting them
into the recesses on the outside surface of the die. For the smaller dies, use the adaptor to fit them into the die stock. -
Ensure that the die stock is kept square to the workpiece at all times. Leading with the chamfered side of the die, start the threading
operation by rotating the die clockwise on the workpiece until it starts cutting into it. -
Continue to turn the die, the cut metal will fill the holes in the die and these should be broken off by turning the die a ¼ turn anti-clockwise,
every ½ a turn clockwise. -
Continue to repeat this action until a thread of the desired length has been cut (ensure that a suitable lubricant is applied regularly).
THREAD RENEWAL
- The taps and dies in this set can also be used for thread renewal to damaged and/or rusty threads. Ensure that the above instructions are followed and that care is taken when starting the re-threading to ensure the original threads are used to avoid cross-threading.
