DescriptionWWS Hammerdrill.ogg |
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.
Tags: coal mine/Coal mining/Colliery/compressed air/pneumatic/Ruhr area/tool/WittenAs 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. |
