Rotary hammer

A rotary power tool comprising:

• a housing;
• a spindle defining a working axis;
• a motor supported by the housing and operable to drive the spindle;
• a handle movably coupled to the housing;
• a vibration isolating assembly disposed between the housing and the handle for attenuating vibration transmitted from the housing to the handle;
• and
• a battery pack removably coupled directly to the handle and configured to provide power to the motor;
• wherein the handle includes an upper portion and a lower portion, and wherein the vibration isolating assembly includes an upper joint coupling the upper portion of the handle to the housing and a lower joint coupling the lower portion of the handle to the housing;
• wherein each of the upper and lower joints includes a rod extending into the handle and a biasing member disposed between the handle and the housing, the biasing member operable to bias the handle toward an extended position;
• wherein each of the upper and lower joints further includes a first bracket fixed to one of the housing and the rod and a second bracket coupled to the other of the housing and the rod, wherein at least one of the first bracket and the second bracket limits movement of the handle to the extended position;
• wherein each of the upper and lower joints further includes a guide disposed within the handle, the guide being slidable along the rod as the handle moves between the extended position and the retracted position;
• wherein each of the upper and lower joints further includes a bumper disposed between the guide and the handle, the bumper operable to attenuate vibration transmitted along a second axis orthogonal to the working axis.
