What is a Tap and Die Set?
A tap and die set contains simply practical tools for creating internal and external threads. Screw threads can be used to fasten nuts, screws, and bolts together. They serve as fasteners for elements of many mechanisms. Each locksmith should have this set because who when the thread can be broken or completely missing. Each set contains at least 9 items of various markings, as usual. The diameter of every element meets the generally accepted hole standard.
Taps are used for applying internal threads in holes: nuts, dies, and others. It’s fixed in the head, inserted into the through hole, and when the master turns the handle, a thread is cut through the hole. There is different labeling of products: from M3 to M12. Each of these diameters is able to cut through grooves in screws and dies.
Dies are used for applying external threads to products: as a rule, on various pins. They are hardened nuts with through holes. The unit is inclosed into the die holder, inserted through the hole on the pin and rotated. A thread is cut at the moment of rotation. It’s applicable for threads on the bolts, screws, and pins creation.
How to Use a Tap and Die Set?
Before you know how to use a tap and die set, here are the specified elements, you will need:
- fully stocked set
- the tap or die of the applicable size
- the material to work with
- a drill that will be used only for tapping
- a grip or vice, due to which the material will be held steadily
- specific cutting oil
- the ratchet to turn the tap into the material’s hole
The following steps on how to use this tool in a proper way:
- Choose the required drill size for the element you are going to use.
- Fasten securely the material.
- Start drilling and gradually increase speed.
- Perform the tapping in order to make the threads.
- Use cutting oil if required.
All the operations should be performed carefully and without sudden movements. If you decide to buy a tap die set, use them in a correct sequence, starting from draft to the end. Otherwise, thread damage and tool breakage are possible. Take a bevel square to check the perpendicularity of the tap relative to the workpiece surface. Choose the correct coolant. However, note that the bronze and cast iron items cut without lubrication. Steel and brass go well with linseed oil, aluminum with kerosene, and copper with turpentine.
How to Choose the Best One?
When making a decision to purchase such a set, it is necessary to take into account several important features that determine the ability to use tools for a particular job performing:
- It is important to define the type of taps and dies that you may need. There are two generally accepted thread standards – metric and inch, but the metric thread is more popular. The cutting edges of the specified die are distinguished by the presence of conical blades.
- It is essential to make sure that the thread on the die has a triangular profile. The user can ensure that the nut is slightly screwed onto the restored thread due to a similar tool.
- There are both manual and machine taps. Hand taps are used in plumbing, and threading is done manually. If you are going to work with viscous materials, such as titanium alloys, it is worth choosing sets that include several taps. In this case, the power-tool thread formation using machine taps can be significantly accelerated.
- Dies are also divided into several types. The most common are taper (are used for initiating a cut or thread), plug (is used for getting neat outcomes the holes’ ends), and circular (it helps get the complete threads in one operation).
- Pay attention to the build quality, as less solid but cheap units won’t be able to carry out their tasks for a long time. Low-quality steel isn’t able to cope with heavy loads.
- It is noteworthy that each set of taps and dies is presented in a convenient case, which can be made of either metal or plastic. This allows you to carry and store the tools comfortably.
