BSP (British Standard Pipe)
This series is a pipe thread which is mainly used for mechanical coupling. The angle of the thread is mainly 55 degrees however for the US method some threads have a 60 degree angle.

Taper Taps - have a lead up of up to eight threads and are used as a starting tap in difficult or high precision holes.

Intermediate Taps - have a lead up of about four threads and are used in most general purpose applications to cut a thread true for a pre-drilled pilot hole.

Bottoming Taps - have a lead up of about two threads and are used to ensure minimum thread run-out when tapping to the bottom of a blind hole. Bottoming taps are typically preceded by the use of a Taper or Intermediate tap.
