A dust collector in one aspect of the present invention comprises a dust collection portion, a communication portion, and an interlock operation control portion. When the communication portion receives an interlock command transmitted from an electric working machine, the interlock operation control portion makes the dust collection portion operate interlocking with the electric working machine. The interlock operation control portion includes a storage portion, in which identification information specific to the electric working machine with which the dust collection portion is to be made to perform the interlock operation is stored.

A hand-held power tool includes an SDS tool receiver and a tool housing. The SDS tool receiver includes at least one vacuuming-off channel and is configured to receive an exchangeable insert tool such that the at least one vacuuming-off channel enables removal of dust produced during operation of the exchangeable insert tool with a workpiece. The tool housing includes at least one drive unit configured to drive the exchangeable insert tool.

A debris collection device includes first and second members that are moveable relative to each other between first and second configurations. In the second configuration, the first and second members interface with each other and define a restraint opening that is configured to receive an elongate element, such as a spinal rod. The first and second members while in the second configuration define a guide opening that intersects the restraint opening. Such guide opening is configured to receive a cutting tool, such as a conical burr, drill bit, mill or saw. The first and second members have walls that, when in the second configuration, collectively define an interior space that has a volume sufficient to collect debris created by cutting the elongate element through the guide opening. Methods of utilizing the debris collection device allow for cutting of a spinal rod or the like in situ while capture debris caused by the cutting procedure.

To provide an improved technique for improving operability in an operation using a power tool with a dust collector attached thereto, a hammer drill to which a dust collector is attached has a body and a handle. The dust collector has a dust collecting part and a male plug. The dust collector is attached to the hammer drill by connecting the male plug to the handle of the hammer drill.

A dust collector for use with a power tool comprises a housing, a telescoping suction pipe coupled to the housing, a suction fan positioned in the housing and operable to generate a vacuum in the suction pipe, a dust container coupled to the housing and positioned upstream of the fan, a filter at least partially arranged in the dust container, and a filter cleaning mechanism. The filter cleaning mechanism includes an anvil, a striker moveable between a first striker position, in which the striker is spaced from the anvil, and a second striker position, in which the striker is in contact with the anvil. The filter cleaning mechanism further includes an actuator moveable between a first actuator position and a second actuator position, in which the actuator is moved closer to the anvil than in the first position, and a first spring biasing the striker toward the anvil.

A machine tool includes a frame with two opposite frame sections, a number of leg elements arranged on the frame, and a first carriage having a first linear axis. The first carriage is guided on the two opposite sections of the frame and is displaceable in a first direction. A second carriage of a second linear axis is guided on the first carriage and is displaceable in a second direction A tower element has a third linear axis, which is retained on the second carriage. A machining element is retained on the tower element and is displaceable in a third direction, and a tool spindle is arranged on the machining element for receiving a tool.

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.

A suction-extraction attachment for an insertion tool includes a housing, a bearing unit, and a suction-extraction opening. The housing has an end-side opening that is configured to accommodate the insertion tool. The bearing unit is configured to mount the suction-extraction attachment on the insertion tool. The suction-extraction opening is configured to couple the suction-extraction attachment to a suction-extraction device. The end-side opening and the suction-extraction opening form a transporting channel. The suction-extraction attachment is configured to be mounted on the insertion tool via the bearing unit in an axially movable and rotatable manner such that a position of the suction-extraction attachment relative to the insertion tool alters as a drill-hole depth increases.

A cyclone pre-separator for positioning on a particle collecting container, the cyclone pre-separator including a box-shaped housing and a cyclone unit arranged in the housing. The cyclone unit includes an air inlet, an air outlet, and a particle outlet arranged on a underside of the cyclone pre-separator, where the housing has an air inlet hose port connected to the air inlet and an air outlet hose port connected to the air outlet, and has lower housing couplers, adapted to provide a releasable, vertically tension-proof coupling to the particle collecting container, when the cyclone pre-separator is positioned on the particle collecting container.

A vacuum tool configured to be removably coupled to hose or wand of a vacuum includes a body including a first end, a second end, and a first longitudinal axis extending between the first end and the second end. The vacuum tool also includes a head coupled to the first end of the body, a connection portion coupled to the second end of the body and configured to couple the body to a hose or wand of a vacuum cleaner, and a brush coupled to the head. The brush includes an elongate support defining a second axis perpendicular to the longitudinal axis of the body and configured to couple the brush to the head, and a plurality of bristles positioned on the elongate support.
