Description
English: The pneumatically driven hammer drill by the manufacturer Flottmann-Werke drills holes into soft or medium-hard rock (for detonations, for example). It was presumably used in the 1940s in the Ruhr-area coal mining industry. Today the hammer drill is an exhibit in the LWL-Industrial Museum Nightingale colliery and is used for presentations.

As with a pneumatic hammer, the hammer drill has a piston moving freely inside a cylinder which hammers on the drill bit using air pressure. The bit is held in a drill sleeve, which is rotated by the piston's return motion causing the drill bit to turn as well.
The supply of air pressure, the interaction of the piston and the drill bit, and the drill bit drilling into the rock create the characteristic sounds of the hammer drill.
