ABSTRACT:
A core breaker carrier for inserting and removing a core breaker from a drill bit. The carrier of the present invention eliminates the need for using wireline tools to install a core breaker within a drill bit. The core breaker carrier with core breaker attached can be inserted into the bore of the drill pipe at the well surface and pumped into the drill bit. Fluid pressure is used to anchor the carrier at a preselected location within the drill bit.
