Abstract: A pipe cutting device is provided. The device is based on a cutting member having a body with a radial pipe entry slot for receiving a pipe at a required cutting position along its length and having a cutting assembly for cutting the pipe upon rotation of the cutting member around the pipe. The device comprises a drive member having a drive means for causing the cutting member to rotate. The drive means is adapted to provide continuous drive to the cutting member body. Drive forces are not temporarily lost as the pipe entry slot rotates relative to a drive means.
