    • A hammer mechanism (14) for a rotary drill (10) comprises a hollow piston (18), a drive (15,26) for effecting reciprocating motion of the piston (18) towards and away from an end portion (35) of a rotatable output spindle (13) of the drill (10) and a ram (21) adapted to slidably locate in a hollow portion of the piston (18). In use, reciprocating movement of the piston (18) is transferred to the ram (21) and the ram (21) periodically strikes the end portion (35) of the output spindle (13), thereby providing the hammer action of the drill. The hammer mechanism (14) also comprises a plurality of guide pins (27,28) fixed in position relative to a housing portion (11) of the drill (10), the piston (18) being provided with a plurality of guide cylinders (23,24) each one of which is adapted to cooperate with a corresponding one of the guide pins (27,27) so as to guide the reciprocating motion of the piston (18).
