Abstract
A bit breaker for making or breaking a connection between a drill bit and a drill string, and the bit breaker includes a support structure that has a bit aperture through which a portion of the drill bit may pass. The support structure also includes basket apertures positioned circumferentially around the bit aperture. The bit breaker also includes a flexible member that passes through the basket apertures of the support structure to form a basket extending from one side of the support structure that can receive a drill bit. Relative rotation between the support structure and the flexible member causes the flexible member to tighten to make or break the connection between the drill bit and the drill string.
