The container assembly also includes a sleeve that is disposed about the external surface of the container, the sleeve includes one or more magnets that couple the sleeve and container to the wall and retain the drill byproduct along the internal surface.

A fastening device for a dust extraction device is configured to detachably connect the dust extraction device to a hand-held power tool. The fastening device includes a first connection unit and a second connection unit. The first connection unit is configured to connect the dust extraction device to the hand-held power tool by form closure. The second connection unit is configured to connect the dust extraction device to the hand-held power tool by force closure.

A dust collecting system includes a power tool and a stationary dust collector. The power tool is configured to perform processing operation on a workpiece by driving a tool accessory. The stationary dust collector is configured to be placed separately from the power tool and to collect dust generated by the processing operation. The power tool includes a first motor and a driving mechanism configured to drive the tool accessory by power of the first motor. The dust collector includes a second motor and a fan configured to be rotationally driven by the second motor to generate air flow for collecting dust. The dust collecting system includes a control device configured to control a rotation speed of the second motor according to a driving state of the power tool.

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 suction hose for a vacuum cleaner including a hose portion, which has a flexible dust removal hose body and a flexible jacket hose body, in which the dust removal hose body is arranged, wherein a suction flow channel for conducting a suction flow to the vacuum cleaner extends between longitudinal ends of the hose portion, which suction flow channel is bounded by a hose jacket of the dust removal hose body, a connection piece for connecting to the hand-held power tool or to the vacuum cleaner is arranged at at least one longitudinal end of the hose portion, and the jacket hose body and the dust removal hose body extend into an interior of a hose receptacle of the connection piece such that the dust removal hose body is sheathed by the jacket hose body into the hose receptacle.

A spray dust compression system and method includes a nozzle holder for affixing a spray nozzle to a percussive tool. The nozzle holder includes an arcuate wall having a first surface engageable with the percussive tool, and a second surface opposing the first surface. A protruding body protrudes radially outwardly from the second surface relative to a longitudinal axis of the arcuate wall and a concave recess is formed in the protruding body and receives the spray nozzle. The concave recess is angled inwardly toward the longitudinal axis of the arcuate wall.

A power tool includes a power tool housing including a fluid inlet and a discharge outlet. A motor is supported by the power tool housing. A tool is configured to be moved relative to the housing by the motor. A fan is configured to be rotated by the motor, such that a fluid flow with debris generated by movement of the tool is drawn into the fluid inlet and through the discharge outlet. A filter is removably attached to the power tool housing. The filter includes a filter media configured to separate the debris from the flow of fluid. The filter media includes a collection container configured to store the debris. The filter also includes an opening in the filter media through which the flow of fluid with the debris enters the collection container, and a valve that is moveable between a closed position and an open position.

An assembly for a hand-held drill is disclosed. The assembly includes a drill guide and a vacuum shroud. The drill guide includes a mount, a telescoping guard, and a guide foot. The mount is configured to couple to a non-rotating portion of the hand-held drill. The telescoping guard extends from the mount. The guide foot is coupled to the telescoping guard opposite the mount such that the drill guide enshrouds a drill bit of the hand-held drill when the telescoping guard is in an extended position. The vacuum shroud is removably fastenable to the drill guide. The vacuum shroud includes an outer wall and a vacuum hose connector. The outer wall forms an elongate vacuum cavity between an inlet proximate to the guide foot and an outlet distal from the guide foot. A vacuum hose connector is positioned at the outlet distal from the guide foot.

A vacuum dust extraction system includes a snorkel coupled to the implement end of an air tool, a dust bellows surrounding the air tool's implement and fastened to the outboard end of the snorkel, a pneumatically powered water filtration industrial vacuum, and a suction hose coupling the snorkel to the vacuum. The apparatus features an improved coupling arrangement for attaching the snorkel to the barrel of the tool driver that permits the apparatus to work with a wide assortment of air tools.

A dust collection box for a dust extractor includes first and second air inlet chambers, an air inlet aperture through which air is drawn into the first air inlet chamber, an air outlet aperture through which air is dawn out of the second air outlet chamber, an air intermediate chamber formed in the housing, and a filter mounted within the housing. The filter includes a first part through which air passes from the air inlet chamber to the air outlet chamber, and a second part through which air passes from the air inlet chamber to the air intermediate chamber. An ambient air aperture is formed in the wall of the housing. A valve disposed proximate the ambient air aperture is switchable to connect the air intermediate chamber to only one of the air outlet chamber or the ambient air aperture.
