Abstract
The invention relates to a device for supplying fluid to a tool (10) for breaking hard material, which is rotatably carried in a holder (11). Means are provided for supplying fluid to a nozzle (24) when the tool (10) is displaced axially rearwards during operation, said nozzle being located in connection with the tool (10). For purposes of facilitating rotation of the tool (10) about the longitudinal axis (29) thereof, the device is designed such that a torque is produced acting on the tool, and the tool seat (13,14) in the holder (11) is flushed when the tool (10) is displaced axially rearwards.
