摘要

The ceiling holes forming pneumatic drill (8) is mounted on a support which holds it in a vertical position and presses it against the ceiling. The support consists of a tube (2) with a bar (3), which can be fixed inside the lower end in an adjustable position. A second bar (4) is similarly fitted in the upper end of the tube. The drill is supported on a platform (22) attached to a short length of tube (15) which can slide on the upper bar. The platform is connected to the piston (6), operating in a pneumatic cylinder (5) fixed to the upper end of the tube. ADVANTAGE - Improved comfort for overhead bore drilling.
