Zusammenfassung:A cutting tool that inserts into a tubular for cutting the tubular from within. The cutting tool includes a motor, a cutting head, permanent anchor between the motor and cutting head, an electronics portion, and a modular anchoring sub that can be between the motor and electronics portion or on the upper end of the cutting tool. The modular anchoring sub provides flexibility in where anchoring elements are positioned so that depending on the application, the modular anchoring sub can be positioned so that it provides its maximum anchoring force for stabilizing the cutting tool during use.
