FAQs


What thread range is this suitable for?


This die set is suitable for thread sizes 20 & 25 mm.

Are there guides included?


Yes, this die set includes 2 guides, 1 to match each die.

How to use a die set


With a hand held die set, select the required die head and secure it in to the die cast. Once securely in place simply place the die set onto the material to be threaded and gently rotate. As it rotates, the die will begin to cut a thread into the material. It is recommended to back the die off half a turn to remove debris after every two full turns.

Should I lubricate the die set?


It is recommended that lubrication is regularly applied to the die set when in use, to allow for friction free threading with precision. This will ensure that a clean thread is achieved with minimal damage.

What is the difference between a tap and die?


A tap set is used to create or repair threads in holes which is ideal for things such as nuts and fittings, this process is called tapping. Die sets are used to cut threads on materials such as steel to allow a fitting to be screwed on and attached, this is called threading.
