摘要： A hydraulic impact hammer having a hammer housing and a hydraulic piston. The hammer housing has means for attaching a hydraulic rotator converter which has a hydraulic rotator for rotating a drill bit for drilling holes on a surface while the drill bit receives pounding action from the piston. The drill bit has surface portions dimensioned to mate with bushing assembles and a cutout region to loosely engage with the locking mechanism in the hammer housing. After the holes are drilled, the converter is released from the hammer housing so as to allow a hammer tool with a larger diameter to be used for pounding over the holes. The hammer tool also has surface portions dimensioned to mate with the bushing assembles and a cutout region to engage with the locking mechanism so that the hammer tool can receive pounding action from the piston for pounding over the holes.

摘要： A handheld power tool has a switchable gear component actuatable by a selector switch. The gear component moves from a first operating position into a second operating position. The selector switch has a first switching position associated with the first operating position and a second switching position associated with the second operating position, and movable so that intermediate positions are assumed. A traveling coupling between the selector switch and the gear component has a spring exerting force onto the gear component in the first direction. A locking bolt is coupled to the selector switch in a positively driven manner. In the intermediate positions, the locking bolt is moved into a blocking bolt position blocking movement of the gear component out of the first operating position into the second operating position. When the selector switch is in the second switching position, the locking bolt is in a releasing bolt position.

摘要： A hammer drill (100) comprises an electric motor (110), a piston (127) as a driving member and a controller (199) which controls and drives the electric motor (110). The piston (127) is reciprocated by rotation of the electric motor (110) and thereby a hammer bit (119) is driven in its longitudinal direction. The hammer bit (119) is moved forward in response to a forward movement stroke of the piston (127) and thereby a hammering operation is performed by the hammer bit (119). The controller (199) sets a duty ratio of a driving pulse signal which drives the electric motor (110) in the forward movement stroke of the piston (127) to be larger in order to prevent a reduction of a rotation speed of the electric motor (110) due to a load applied on the electric motor (110) during the forward movement stroke of the piston (127).

摘要： A rotary hammer includes a housing, a battery pack removably coupled to the housing, a brushless direct-current motor supported by the housing, and a spindle coupled to the motor for receiving torque from the motor. A piston is at least partially received within the spindle for reciprocation therein. An anvil is received within the spindle for reciprocation in response to reciprocation of the piston. The anvil imparts axial impacts to a tool bit in response to reciprocation of the piston. The rotary hammer also includes a bit retention assembly for securing the tool bit to the spindle. The rotary hammer is operable to produce an average long-duration power output of at least 500 Watts and to deliver at least 5 Joules of blow energy to the tool bit for each of the axial impacts.

摘要： An electric boring tool comprises an electric motor, a switch trigger, a tip tool driven by driving force of the electric motor, a power transmission mechanism for transmitting the driving force of the electric motor to the tip tool as rotational force and/or hammer force, and a motor control unit for controlling speed of the electric motor in response to an extent of pulling of the switch trigger. The motor control unit subjects the electric motor to low speed control after the electric motor is started up, and controls the speed of the electric motor in response to the extent of pulling of the switch trigger when the load current of the electric motor is set value or greater during the low speed control.

摘要： A power tool having a rotary impact mechanism and a mode change mechanism. The impact mechanism is driven by an output member of a transmission and includes a hammer and an anvil. The mode change mechanism includes a mode collar that is movable between a first position, in which the mode collar directly couples the hammer to the transmission output member to inhibit movement of the hammer relative to the spindle, and a second position in which the mode collar does not inhibit movement of the hammer relative to the spindle.
