Abstract
A rotary hammer tool can include a housing, a first motor supported by the housing, a spindle rotated by the first motor, a second motor supported by the housing, and a reciprocation mechanism reciprocated by the second motor. The reciprocation mechanism can include a piston driven to reciprocate within the spindle and a striker to reciprocate within the spindle in response to reciprocation of the piston. The rotational speed of the spindle and a reciprocation frequency of the reciprocation mechanism may be independently controllable.
