If you are planning to buy your very own tap and die set, be sure that you know its different types. Knowing each type of tap and die will help you determine the best tools that a set should include. So, check out this list below before you decide on purchasing anything:


  • Taper Tap

This type of tap is designed to start a thread around a hole. It is commonly shaped from the top which starts from its bottom point up to its 6th thread. The best thing about this tap is that it can create a full thread around a hole.

  • Second Tap

As its name suggests, this tap is used to reinforce and deepen the threads made by a taper tap. This is commonly used for blind holes where the virtual ends of the drill don’t exist. The only similarity that a second tap has with the taper tap is its first 6 threads.

  • Plug Tap

Compared with the two types of tap above, this tap isn’t shaped like the others because it is designed to enhance the finished look of blind holes to the ends.


  • Circular Die

If you want to create a complete thread through a single operation, you only need a circular die. This type of die is tapered only on one side to start a smooth operation. But, this die isn’t ideal if you want to make adjustments on the screws due to its springiness. So this die is generally used for cutting small thread types only.

  • Two-Piece Adjustable Die

For producing longer threads, a two-piece adjustable die is commonly used. However, it takes more than a single operation to make longer threads since it closes after making each thread. The final cuts are made once etched numbers over it meet on the same side.
