An electrically powered hammer comprising a hollow cylindrical spindle mounted within a housing. A portion of the spindle is formed with a plurality of circumferentially spaced holes and a corresponding number of peg elements are fitted to the spindle, such that each peg element extends through a corresponding hole in the spindle and radially inwardly of the internal surface of the spindle, in such a way that the peg elements together form an axial stop for one or more additional hammer components located within the spindle. Each peg element may alternatively or additonally extend radially outwardly of the corresponding hole in the spindle, in such a way that the peg elements together form an axial stop for one or more additional hammer components located around the spindle. The axial stops formed by the peg elements can replace circlips, which are generally used to form the axial stops. |
