ABSTRACT:
A portable tool of the basic type generating vibration during operation is improved by the provision of a hollow insert into the cavity or space of the handle that is filled with shock-absorbent material. The insert opens at the front of the handle and is internally threaded to receive the externally threaded rear part of the barrel, for example, of an accessory or attachment, such as a chipper, chisel or the like. A separable lock is provided for preventing accidental unscrewing of the barrel.
