ABSTRACT:
The tubular cutter disclosed herein is useful for severing downhole tubulars and comprises a drive system, a pivoting system, a cutting head, and a cutting member. Cutting is accomplished by rotatingly actuating the cutting head with an associated motor, and then radially extending the cutting blade away from the cutting head. In one embodiment, the cutting head includes a cutting member that pivotally extends from the cutting head upon rotation of the cutting head.
