Abstract: A rotary power tool comprises a drive mechanism including an electric motor and a transmission, a housing enclosing at least a portion of the drive mechanism, a spindle rotatable in response to receiving torque from the drive mechanism, a first ratchet coupled for co-rotation with the spindle, a second ratchet rotationally fixed to the housing, a sleeve bushing supported by the housing, and a bearing rotatably supporting the spindle. The spindle has an outer race. And, the outer race of the bearing moves along the sleeve bushing during reciprocation of the spindle when the first ratchet and second ratchet are engaged.

Abstract: Handle apparatus on a power tool, in particular a chipping hammer, having a drive, a control device, a transmission device, wherein the handle apparatus contains a lever element that is pivotable relative to a housing of the power tool. The lever element is movable reversibly relative to the housing of the power tool by exertion of a force in one direction, and a sensor device is contained for sensing at least one first or second position of the lever element relative to the housing of the power tool, wherein a first rotational speed value for the drive is settable depending on the first sensed position of the lever element relative to the housing of the power tool or at least one second rotational speed value for the drive is settable depending on the second sensed position of the lever element relative to the housing of the power tool.

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.

Abstract: A power tool can receive two different auxiliary handles in a replaceable manner. A power tool includes a tool body, a main handle, a cylindrical handle mount to which a first auxiliary handle or a second auxiliary handle is attachable and having a groove, the first auxiliary handle, and the second auxiliary handle. The first auxiliary handle includes an arc-shaped first band, a band holder that changes the diameter of the first band, and a first protrusion engageable with the groove. The second auxiliary handle includes an arc-shaped second band having a cutout in an axial direction, a fastener that changes the diameter of the second band, and a second protrusion engageable with the groove.

Abstract: A rotary hammer includes a housing, a first motor supported by the housing and defining a first motor axis, a second motor supported by the housing and defining a second motor axis that is coaxial with the first motor axis, and a spindle coupled to the first motor for receiving torque from the first motor, causing the spindle to rotate. The rotary hammer further includes a reciprocation mechanism operable to create a variable pressure air spring within the spindle. The reciprocation mechanism includes a piston configured to reciprocate within the spindle in response to receiving torque from the second motor, a striker that is selectively reciprocable within the spindle in response to reciprocation of the piston, and an anvil that is impacted by the striker when the striker reciprocates towards the tool bit. The anvil imparts axial impacts to the tool bit.

Abstract: A power tool includes a housing and an electric motor supported within the housing. The housing includes a main housing portion that defines a rear opening. The electric motor includes an output shaft supporting a rotor assembly for rotation about a motor axis. The electric motor also includes a stator assembly surrounding the rotor assembly, and a rear end cap. The rear end cap supports a rear motor bearing that rotatably supports the output shaft at a rear end. A portion of the rear end cap resides within the rear opening to close the rear opening.

Abstract: A power tool includes a motor, a housing, a battery holder and a cushion. The battery holder is held by the housing to be movable at least in a first direction relative to the housing. The battery holder is configured to removably receive a battery for supplying electric power to the motor. The cushion is held by the housing such that the first direction intersects the cushion. When the battery is attached to the battery holder, the cushion is directly or indirectly disposed between the battery and the housing.
