A hollow drill device for producing a drilled hole includes a suction head, where the hollow drill device is connectable to a dust extraction device by the suction head, a sensor, where a pressure condition in the suction head is determinable by the sensor, and an indicator. A quality grading of a cleaning of a drilled hole is indicatable by the indicator in dependence on a determined pressure condition in the suction head by the sensor.

A dust collecting attachment removably attachable to a power tool that includes a housing and a spindle: a covering part formed such that a drive axis of a spindle passes through the inside of a suction hole in the attached state of the power tool and at least partially covers a periphery of the tool mounting part; a discharging part connected to the covering part and configured to discharge dust from the inside of the covering part; and at least one elastically deformable engagement piece connected to the covering part and having a claw configured to engage with the housing at a predetermined position of the housing.

Control method for a dust extraction module (2) for a chiseling tool (5), including the following steps: using a fan (18) of the dust extraction module (2) to draw in an air flow Q from a certain place of a substrate (31) being worked by the tool (5), using a material detector (24) to identify the material M at the place of the substrate being worked by the tool (5), and adapting the suction power of the dust extraction module (2) as a function of the identified material M in order to set the air flow Q. The air flow Q is greater than or equal to a rated value Qo in the case of an iron-free mineral material M1, whereas the air flow Q is less than the rated value Qo in the case of a material M2 containing iron.

A dust hood for a power tool, wherein the dust hood includes an extraction region in which a suction hose coming from a dust-sucking device opens into the dust hood. The dust hood has a curvature in the extraction region, wherein the curvature makes it possible for an impulse surge which is generated within a filter cleaning operation of a dust-sucking device to be attenuated by reflection.

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 debris receptacle for a router table includes an enclosure configured to be attached to the router table. The enclosure defines an interior sized and shaped to receive a router. The enclosure defines a debris inlet aperture in fluid communication with a router bit aperture of the work platform so that the interior receives the debris from router bit aperture via the debris inlet aperture. The enclosure also defines a debris outlet aperture in fluid communication with a dust collector to remove debris from the interior. The enclosure further defines an air inlet aperture in fluid communication with air in an environment outside the enclosure. The debris receptacle also includes an air intake conduit for fluidly coupling the air inlet aperture to an air inlet of the router, thereby enabling the router to draw air into the router from the environment outside the enclosure to cool the router.

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.

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.

An accessory for an electric drill is disclosed as including a dust box for receiving abraded materials produced by an electric drill on a workpiece, the dust box including an internal cavity, a first longitudinal end with a first opening communicating with the internal cavity, an opposite second longitudinal end with a second opening communicating with the internal cavity, and a brush or a disc. When a drill bit of the electric drill is received into the internal cavity of the dust box through the second opening, the brush or disc is releasably engageable with the drill bit for simultaneous rotational movement about a longitudinal axis of the drill bit.

A suction nozzle (100) for a hand-held milling machine (200), the suction nozzle (100) including a suction connection (30) designed for connection to a dust extraction system (300), and the hand-held milling machine (200) being equipped with a depth stop (210), with the aid of which a penetration depth (ET) of a milling tool (220) of the hand-held milling machine (200) may be limited, the suction nozzle (100) having a connection area (10), via which the suction nozzle (100) is detachably fastenable, in particular detachably fastenable without tools, to the depth stop (210).
