There are many situations that may require the need for a tap and die set. If you’ve ever broken a screw off inside a hole then you know how frustrating it can be. It can be used to remove the remnants of the screw. If the threads are damaged inside, these tools can also be used to cut new threads cleanly so you can use a new screw in its place. If you’re working with a material that needs to be threaded, the tools are also useful for creating threads in both the hole and the rod that goes inside. Here are some tips that will help you know what tap and die is, how to find the right set and how to use them.

What is a Tap and Die Set?
A tap and die set is a group of two separate tools. These tools are used to cut threads into the material that surrounds a hole. They are also used for cutting threads into a rod that will fit into a threaded hole. The tap is used when cutting the threads into the hole and the die is used for cutting threads into the rod. These are two tools that are easy to use once you get the hang of them.
Start With Choosing The Right Tap and Die Set
Tap and die sets come in different materials. It’s a good rule of thumb to choose a set that is made of strong materials because they are exposed to a lot of pressure and impacts. The sets that are made of strong and impact-resistant steel and high speed steel are the best choices.
Step 1: Determine the size
Before you start drilling the hole, you must determine the size that you need to drill. You can find the corresponding size labeled clearly on your tap and die set so this takes the guesswork out if you know the size of the hole that needs to be drilled.
Step 2: Fasten the material
Fasten the material that you are going to drill securely with clamps so it doesn’t move while you’re making the threading cuts. This is very important to help you get a clean cut with threads that will work efficiently. You can use a clamp or a vice to hold them in place.
Step 3: Chose the bit size
Select the right size bits for the hole size. It’s important to start with this step to drill out the hole before you begin the tap process to cut the threads. Secure the bit into the drill. Start drilling slowly at first. If you’re working with hard materials like cast iron or steel, you might want to use cutting oil to ease the heat of friction. Take your time and drill slowly for the best results.
Step 4: Tapping
Once the hole is cleared, insert the tap into a ratchet. Put the tap into the hole and begin turning. Turn clockwise. Turn it slowly until the tap has made a few threads. Here is the technique that is important to use to get a clean cut. Make two turns clockwise, then back the tap out by a half turn the other way. This ensures that small particles do not damage the new thread cuts as you proceed. Keep the material you’re cutting flat and stable at all times with the tap level and centered.
Step 5: Completing the tapping process
When you’ve completed the process, turn the ratchet counter-clockwise to remove.
Step 6: Choose the right size of die
For the next step, select the right size of die needed. This will make the threads in the rod part that will fit into the new threaded hold that you’ve created.
Step 7: Secure the rod in a vice or clamp
Secure the material that you are going to thread in a manner that is stable and solid so there will be no movement. You can use a vice or a clamp.
Step 8: Prepare the rod
File the end of the rod so it is clean and square. Apply cutting oil onto the material you will thread.
Insert the die into the die wrench and secure it in place.
Push the die onto the material being threaded. Make sure that it is centered over the rod.
Turn the wrench clockwise. You will follow the same steps as you did for the tap, turning for 2 turns clockwise, then backing it out counter-clockwise one half turn and clearing the debris. This will give you a clean cut and straight threads on the rod.
Continue lubricating the rod while cutting. Follow these steps until you’ve threaded the length of the rod that is needed. Remove the die wrench from the material and brush away any debris and you’re done.
Using a tap and die set can save you the cost of taking an item with a broken screw to a machinist. It’s not difficult to use these tools to make your own repairs from home. It can save you a lot of time and money and it’s a skill that is easy to learn. It’s good to have a tap and die set on hand in case you have such an emergency.
If you’re a craftsman who works with metal, you might also enjoy using a tap and die set for screwing together your own creations. These handy tools have a lot of different uses. If you decide to make an investment in a tap and die set, choose a product that is made of the strongest possible steel material so you can use them on any type of material. Knowing how to properly use a tap and die set is a great skill to possess.
