Appropriate control is performed in accordance with the state of a power tool and/or a dust collection attachment. A dust collection system for a power tool includes a hammer drill to hold a bit, a dust collection attachment connected to the hammer drill, and a dust collection controller that controls the operation of the hammer drill and/or the dust collection attachment in accordance with the specifications of the hammer drill and/or the dust collection attachment.

A power tool system and to a method for connecting a vacuuming device to a power tool. The system comprises a power tool having a tool, a vacuuming device for extracting dust that arises when working with the power tool, and a suction connection device, wherein the suction connection device is arranged between the tool of the power tool and the power tool and is connectable to the power tool in that a toothing of the power tool is able to be engaged with a mating toothing on the suction connection device. The present invention advantageously makes it possible for a suction hose that connects the vacuuming device and the suction connection device of the power tool system together to be able to be fixed relative to a handle of the power tool. Furthermore, an angle between the suction hose and the handle of the power tool can be set particularly easily.

A mist collector includes: a filter that collects mist; a nozzle including an ejection port capable of ejecting a coolant, the nozzle being disposed to cause the ejection port to be opposite to the filter; and a motor that causes the filter to move, to cause a position on the filter to which the ejection port is opposite to change.

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 electric device in the shape of a machine tool or an energy storage module for the electric power supply of a machine tool, with the energy storage module having a module housing with a device interface for the detachable connection to the machine tool, with the machine tool having a drive motor to drive a tool holder on which a tool provided to process a workpiece is arranged or is arrangeable, with the drive motor being switchable using a switching element of the machine tool and/or the energy storage module, with the electric device having a wireless communication interface for wireless communication with an external communication apparatus, which forms part of a vacuum cleaner provided to suction dust generated by the machine tool and with the wireless communication interface being designed to send at least one control command to control, the vacuum cleaner as a function of a switching status of the switching element to the external communication apparatus via a wireless control connection.

The chip guiding device comprises a shield configured to be arranged at a rotating axis (A) of one of the machine moulder's cutter heads, such that the shield, when the machine moulder is in operation, guides the chips cut by the cutter head's cutter knives from a workpiece into a hose connected with the chip extractor. The shield may be configured to rotate together with the cutter head. The shield may be circular formed with a central hole for arranging the shield at the rotating axis (A). The shield may be provided with fan means to increase an airflow towards the hose. By providing the cutter heads of a machine moulder with chip guiding devices at the rotating axes, connected chip extractors may collect larger amounts of cut chips, and contribute to improved performance of the machine moulder.

A self-dust extraction dustless table saw includes a table saw frame, saw table, and saw blade installed to the table saw frame. An upper and a lower blade guards are respectively mounted to upper and lower sides of the saw table, the saw blade is mounted in the upper and lower blade guards, and the lower blade guard includes a lower left and lower-right blade guards. Several interval guide barriers are installed on the inner walls of the lower left and lower right blade guards, and the guide barriers transport the dust to a dust outlet on the side of the lower right blade guard.

The present disclosure is directed to calibrating position detection for a tool. The tool can use a sensor to detect a first value of a parameter. The tool can use a motor to extend the working member of the tool towards a working surface. The tool can include a base. The tool can detect, with the working member in contact with the working service, a second value of the parameter. The tool can determine a z-axis position of the working member relative to the working surface.

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 including 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 method of forming a compact includes removing material from a workpiece, transferring metallic dust released during the material removal into a conduit, operating a plurality of slide gates to selectively control movement of the dust from the conduit to either one of a primary collector and a back-up collector, drawing the dust through the conduit to a compactor, and compacting the dust in the compactor.
