Abstract
A downhole cutting tool may include a tubular housing securable to a downhole end of a conveyance and a cutting head secured to the tubular housing. The cutting head may have a retractable cutting blade configured to move between a radially extended position and a retracted position. Additionally, the cutting head may be configured to rotate with respect to the tubular housing to drive the retractable cutting blade, in the radially extended position, to cut a downhole tubular disposed in a wellbore. The downhole cutting tool may also include at least one motor secured within the tubular housing and configured to drive rotation of the cutting head. Further, the downhole cutting tool may include a power source disposed within the tubular housing and configured to supply power to the at least one motor, and the power source may include at least one battery.
