摘要: A directional drilling apparatus for mounting a drill bit on a rotatable drill support comprises a member for transmitting rotation from the drill support to a drill bit, and a body mounted to the member. The body is configurable to offset a portion of the member relative to an axis of the body such that directional drilling may be achieved.
