Abstract

The invention is concerned with a pneumatic drill for use in a borehole having a tubular body enclosing a shock-absorbing piston through which the compressed air is supplied, a distributor unit, a percussion piston, and a drill bit which receives the blows from the percussion piston and transmits them to the rock. The percussion piston is movable in a cylinder formed by an inner liner, and between the liner and the inside wall of the drill body lie longitudinal passages for the supply of compressed air to operate the piston and other passages for the discharge of the air after it has acted on one of the faces of the percussion piston. The invention provides in such a drill a flushing fluid supply means which bypass the percussion piston and drill bit by way of longitudinal ducts for the fluid extending from a distributor to escape ducts extending through the body.
