Abstract: A drilling system (10) for drilling holes into concrete includes a drilling tool (20) attached to a frame (22) that can be secured to a drilling surface (S) of any orientation and permits (1) manual, (2) manual-power-assisted, or (3) stand-mounted, hands-free operation of the drilling tool (20). The system (10) utilizes air pressure, vacuum, gas regulating system, or even magnetism, to secure the frame (22) of the drilling tool (20) to the surface (S) and to control the movement of a drill bit (34) with respect to the surface (S). A fluid delivery system (80) is used to facilitate certain actions of the drill bit (34) and to effectively remove debris resulting from drilling from the drilling site. Also disclosed are related methods of drilling holes into concrete that reduce noise, mess, and debris resulting from drilling.

Abstract: A pipe running tool for use in an oil drilling system and the like comprises a lower drive shaft adapted to engage a drive shaft of a top drive assembly for rotation therewith. The pipe running tool further includes a lower pipe engagement assembly which is driven to rotate by the lower drive shaft, and is designed to releasably engage a pipe segment in such a manner to substantially prevent relative rotation between the two. Thus, when the lower pipe engagement assembly is actuated to securely hold a pipe segment, the top drive assembly may be actuated to rotate the top drive output shaft, which causes the lower drive shaft and lower pipe engagement assembly to rotate, which in turn rotates the pipe segment.

Abstract: An arrangement in a rock drilling apparatus comprising supports (5) directed toward the rear part of the feed, the supports being moveable by means of support cylinders (6) to support the feed during the drilling operation. The arrangement comprises a pressure detector (9), which is arranged to detect the pressure of the pressure fluid in the support cylinders (6) and to make the control unit supply more pressure fluid to the support cylinders (6) when the pressure drops below a pre-set threshold value.
