Die sets are a type of hand tool designed for cutting thread in a range of materials such as steel. Die sets feature die heads in various sizes to accommodate a range of applications, with many offering additional extras such as blocking vices and reducers to stabilise the threading process. Die sets are often used in conjunction with tap sets and tap wrenches to create a clean and secure thread fitting. Die sets are commonly used in applications such as:

• Electrical servicing
• Automotive
• Plumbing

Are die heads included?

Yes, this die set includes 5 die heads in various sizes including:
3/8, 1/2 ,3/4, 1 inch and 1 1/4 inch BSP.

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.


A seperate 1/4 inch BSP die is also available separately (stock no. 205-2306)
