  • Device for transmitting impulse-like blows to a continuously rotatable tool bit
    Patent number: 5820312
    Abstract: A device for transmitting impulse-like blows to a continuously rotatable tool bit (6) is formed as an axially extending adapter (1) having a first chuck for the tool bit (6) and being insertable at a trailing end into a second tool bit chuck in a manually operated tool equipped with a striking mechanism. The adapter (1) has a housing (2) containing a unit for superimposing a second blow component on the first impulse blow component produced by the striking mechanism, so that an impulse-like drilling blow can be transmitted to the drill bit (6) made up of an axially directed blow component and a torsional blow component.
