Abstract (en)
[origin: EP1174225A1] The tool has a hammer tool device (1) with tool head (4) which is rotationally secured with the tool shaft and is movable axially restricted and which with regards to its impedance is adapted acoustically to the fly piston (5) of the hammer tool. The abutting end faces (10) are in at least partial surface contact with each other. The acoustic length of the tool head is half the length of the shock pulse (7) excited by the piston.
