Plug tap
The plug tap is almost without a taper (just one tapered thread) and has a continuous cutting edge. It makes it suitable for cutting threads to the bottom of a blind hole. A plug tap cannot start the tapping process of an unthreaded hole because of the short tapered end. Other tapping types with a tapered end start the tapping process before a plug creates a continuous thread to the bottom.
Second tap
The second tap has 3 – 5 tapered threads and can therefore start the tapping process. It is the most common type of tap used. The tapered end assists in centering and aligning the tap to the hole.
Taper tap
The taper tap has 8 – 10 tapered threads. Tapping hard materials that require slow tapping or in small applications where the tap can easily break is where the taper tap works best.
