Abstract: A breakout wrench for use with a rock drill string includes a frame adapted for mounting to a rock drill feed guide structure, and a sub-frame rotatably connected to the frame about a drill string longitudinal axis. The sub-frame supports a pair of jaw members adapted for radial movement towards and away from one another and to releasably engage a first section of a drill string. The breakout wrench also includes a clamping member supported by the rock drill feed guide structure. The clamping member is adapted to releasably engage a second section of the drill string spaced axially from the first section.

Abstract: The drill rod (10) includes a first rod section (14) and a second rod section (16) that are welded together along their mating ends (14b and 16b respectively). The mating ends are heat treated to reduce the elevated hardness that is caused by the welding. Both, the first rod section and the second rod section, each include an interior passage (15 and 17 respectively) that extends between the free end (14a and 16a respectively) to the mating end. A hardened externally threaded portion (18) on the first rod section can be threaded into the separately hardened internally threaded portion in the interior passage of a second rod section of another drill rod. The first drill rod is threaded into the other drill rod so that the surface of an annular face on the free end of the first drill rod abuts against a mating shoulder of the second drill rod.

Abstract: A cam assembly is provided for adjustment of a drill feed guide wear pad. The cam assembly has an eccentric bushing with a shank portion extending circumferentially about a first axis and defining a bore along a second axis. The second axis is generally parallel and offset from the first axis. The bushing has a head portion extending from the eccentric bushing portion, with the bore extending though the head portion. The bushing is sized for insertion into an aperture of a drill feed guide wear pad, and is rotatable causing the shank portion to engage the aperture of the wear pad to provide a camming action to position the wear pad relative to a drill feed guide. The head portion is shaped to interact with a tool for rotating the bushing.
