Tubular cutting device

Abstract

The casing cutter disclosed herein is useful for severing downhole tubulars and comprises a body, a cutting head, cutting blades, and actuators for operating the cutting head and cutting blades. Cutting is accomplished by rotatingly actuating the cutting head with an associated motor, and then radially extending the cutting blades 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. In another embodiment, cutting members extend from the cutting head due to centrifugal forces associated with rotating the cutting head.
