Do you have a broken bolt or screw that you need to remove?
Are you trying to hang a painting, repair a vehicle or lawnmower engine, or complete a do-it-yourself project in your home and you need to create or repair threads?
If these are issues that you face, you will need to learn how to use a tap and die set.
While the concept may seem overwhelming at first, especially if you are not particularly good with your hands, it is a skill that can easily be acquired with a bit of patience and lots of practice.
First, you must know what these tools do, and the difference between the two. Taps are tools that create threads within a material, and dies are tools that create threads on the outside of a material.
It is so very important to have this knowledge because you never know when you may need to create threads.
For example, you may be fixing a plumbing leak and need to make a new pipe, or you may be building your son and daughter a tree house and you accidentally strip a couple of bolts.
In nerve-wracking times like these, a working knowledge of tap and die sets can come in handy!
Materials Needed to Follow this Tutorial
It is always important that you have all your materials ready and available in advance. This will ensure that the process goes smoothly and you won’t have to stop and search for a critical component in the middle of working.
It is always best to have everything prepared and in front of you ahead of time when you are starting any type of project that requires a wealth of materials.
You may have thought that all you needed was a good tap and die set, but you will actually need additional materials in order to properly cut threads on the inside and outside of a given object.
Here is everything you will need before you get started:
- A fully stocked tap and die set, with taps and dies in several different sizes to accommodate the many different jobs that you may need to use them for
- The tap or die in the appropriate size to create the threads or cuts that you need
- The material that you wish to thread or cut on the outside or inside
- A drill (for tapping only) – this is to create a hole in a material in which threads or cuts will be made. This is not necessary when you are using a die to make outside cuts and threads
- A vice or grip to hold the material steadily while you make the threads
- A ratchet to turn your tap into the hole in the material and a die wrench to turn your die around the material
- Cutting oil to soften and make more malleable hard materials such as cast iron, nickel, titanium, or steel
Using a Tap
Choose the Correct Drill Size for the Tap you Intend to Use
Most kits will come with a standard guide that will help you with this step. Follow the charts to see what is required.
Fasten the Material you will Cut Securely
Insert the intended material into your vice or clamp. Once the material is in a position where it can no longer move or slip, you are ready.
When you begin to drilling the hole for your tap, start at as slow a speed as possible. Always apply cutting oil on harder surfaces to soften them up appropriately.
Start Tapping to Create Threads
Insert the tap and use the ratchet to slowly turn the tool. Turn the tap completely around in a clockwise manner two times, then backtrack half a turn.
This method prevents broken material from damaging the inside of your new thread while you work. Apply cutting oil as needed.
Using a Die
Choose the Correct Sized Die for your Job
You can easily figure this out if your dies are arranged in the correct order. Just take the one that looks the most appropriate, and see if it fits. If it does not, then try a size larger or a size smaller until you get the right one.
Fasten the Material You will Cut Securely
Again, snugly fasten your intended-to-be-cut material using the vice.
File the Material
Be sure the end of the rod that you intend to thread is square.
Insert the Die into the Die Wrench and Begin Cutting
Apply some cutting oil and place the die over the material. Turn the wrench clockwise, and like the tap, make two full turns with a half a turn backwards.
