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.

An ultrasonic cutter includes a tool holder and an ultrasonic oscillator. The tool holder has a lower circular air-out aisle defined by sleeving an inner ring and an outer ring. The inner ring has oppositely a first surface and a second surface, and the outer ring has oppositely a third surface and a fourth surface. A gap spacing the first surface from the third surface has an upper air inlet and a lower air outlet. The second surface has a lower inner inclined surface forming a first angle with the first surface. The fourth surface has an outer inclined surface forming a second angle with the third surface. The ultrasonic oscillator, disposed in a chamber of the tool holder spatially connected with the gap, is used for providing ultrasonic oscillation to a cutter. In addition, a cooling and chip diversion system for the ultrasonic cutter is also provided.

A dust collector for use with a hand-held power tool. The dust collector includes a housing, a motor positioned in the housing, and a telescoping suction pipe coupled to the housing. The dust collector also includes a suction fan coupled to the motor and operable to generate a vacuum in the suction pipe. The dust collector further includes a dust container coupled to the housing and positioned upstream of the suction fan, and a filter at least partially arranged in the dust container. The dust collector also includes a filter cleaning mechanism including a solenoid configured to be actuated by a controller to dislodge dust from the filter when either the motor or the suction fan transitions from an active state to an inactive state.

A suction device for a hole saw of a hand-held power tool oscillatingly driven about an oscillation axis. A substantially disk-shaped base body has a first side that faces the hand-held power tool and a second side that faces the hole saw. A fastening section detachably fastens the suction device to an oscillatingly driven hand-held power tool; and a connecting piece connects the suction device to a suction apparatus.

The invention concerns a drilling device (1) and a method for drilling holes in a stack of material (100). The drilling device is provided with clamping means (23, 26) for clamping the material, a hollow drill (10) with an internal channel and a drive (3) for the hollow drill. The drilling device is further provided with connecting means (4) for cooling means, that are arranged for conducting gas through the internal channel, and suction means (51) for suctioning drilling debris. The drilling shaft is provided with a cut out, that runs in longitudinal direction along the drill shaft and forms a discharge channel for the drilling debris.

The invention also concerns a machine for machining and assembling window coverings, such as pleated blinds, comprising one or more drilling devices according to the invention.

A dust collector is operable to collect dust and debris generated during operation of a power tool. The dust collector includes a mounting base configured to couple to the power tool, a tether coupled to the mounting base, and a shroud extending from the mounting base. The mounting base defines a longitudinal axis. The tether is configured to be wrapped around a portion of the power tool. The shroud includes a first end adjacent the mounting base, a second end operable to contact a workpiece, and a sleeve extending between the first end and the second end.

A suction adapter, in particular a suction drill suction adapter, for connecting an insertion tool, in particular a suction drill, to a suction apparatus includes at least one insertion tool receiving region, in which the insertion tool is arranged, at least one connection interface with respect to an insertion tool suction channel of the insertion tool, and at least one, in particular dimensionally stable, discharge guiding unit configured to delimit a suction channel. The at least one discharge guiding unit has at least one discharge guiding element configured to delimit a suction channel outlet of the suction channel and which has a longitudinal axis. The longitudinal axis of the at least one discharge guiding element is orientated parallel with a main extent axis of the at least one insertion tool receiving region in a region of the suction channel outlet in at least one operating state.

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 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.

Wall sealing and penetrator apparatus for use in penetrating walls in dangerous conditions. An example wall sealing and penetrator apparatus includes a first portion comprising: a first housing, a first sealing element, a first vacuum port; and a second portion comprising, a second housing, a second sealing element, a second vacuum port, and a cutting element.
