摘要:
A system for disassembling components of a drill string includes a primary wrench, a secondary wrench, and a bit removal basket. The primary wrench has a pair of jaws in which at least one of the jaws is moveable in relation to the other. The secondary wrench is disposed at a position lower than the primary wrench and is configured to define a pair of beveled faces that are adapted to restrict a rotational movement of at least one component of the drill string. The bit removal basket is disposed at a position lower than the secondary wrench. The bit removal basket is configured to define an opening therethrough. A shape of the opening is configured to correspond with profiles of at least two types of drill bits, one of the at least two types of drill bits being present for use in the drill string.
