MSZ Special cutting tap
MSZ Special cutting tap is designed for pulling the drill string ending with the collar or the drill-pipe pin out of the well, weighted by the drilling pipe, the adapter sub, an upset part of the drilling pipe and a thin part of the pipe via clamping their inner surface. МСЗ cutting taps are used for clamping by screwing in the locking thread.
Cutting taps are produced with right-handed and left-handed thread.
