When would you use a tap for a thread  A taper tap is most often used when the material is difficult

Does the hole need to be bigger or smaller , explain why .Using the correct hole size is important on two points. First, if the hole is too large, the root of the threads will be too shallow and insufficient and may strip out or fail. 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 taps are normally used in through hole applications or as a starter tap for blind holes. ... In blind hole applications, Plug taps are used after a Taper to get closer to the bottom of the hole. Bottoming tap have a 1.5 thread chamfer.
