How to use Taps and die sets in engineering: Taps and dies are tools used to create screw threads, which is called threading. Many are cutting tools; others are forming tools.

What is tap and die used for in Engineering? Taps and dies are tools used to create screw threads, which is called threading. Many are cutting tools; others are forming tools.

When would you use a tap for a thread? A tap is used to cut or form the female portion of the mating pair (eg a nut). A die is used to cut or form the male portion of the mating pair (eg a bolt)

Does the hole need to be bigger or smaller, explain why. Use The Correct Hole Size

If the hole is too small, it will cause the tap to bind and quite possibly break trying to cut too much material.

What are the different types of tap ( taper, intermediate, taper) explain the difference between them 

Taper Tap

A taper tap has quite a lot of taper to help it ease into cutting threads gradually.   Typically, the first 8 to 10 threads are tapered.  Taper Taps are the most common types of taps and are typically what you’ll have in a Tap and Die Set.

Bottoming Tap

A bottoming tap has almost no taper at the end because it is designed to thread all the way to the bottom of its reach.  Only 1 to 1.5 threads will be tapered. Bottoming Taps are useful for threading blind holes.  It’s desirable to thread most of the hole with a Taper Tap first, and then finish the bottom of the hole with a Bottoming Tap.

Plug Tap

Plug Taps are in between Bottoming and Taper Taps because they have 3-5 threads tapered, which is more than a Bottoming Tap and less than a Taper Tap. Unfortunately, the terminology is not always consistent.  Some vendors call these “Second Taps” and refer to Bottoming Taps as Plug Taps.  Check to be sure what you’re getting and using.
