A handheld power tool including a housing, a tool receptacle disposed on a first end of the housing and configured to receive a tool accessory, and a motor positioned within the housing and operatively coupled to the tool receptacle to drive the tool accessory. A dust container is selectively coupled to the housing. A dust tube is coupled to the first end of the housing and in fluid communication with the dust container, wherein the dust tube is movable between an extended position and a retracted position. A fan is positioned within the housing and is operable to generate a suction air flow path through the dust tube and into the dust container, wherein the fan rotatably driven by the motor.

A self-adjusting pocket hole jig system is presented having a base, an upright assembly operably connected to the base, a clamping assembly, operably connected to the upright assembly, a handle operably connected to the clamping assembly, and a drill guide assembly operably connected to the clamping assembly. The drill guide assembly is configured and arranged to move along the upright assembly between an unclamped position and a clamped position in response to movement of the handle. Movement of the handle simultaneously adjusts the height of the drill guide assembly as well as facilitates clamping of the drill guide assembly for workpieces of various thicknesses.

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 power tool assembly includes a hand-held power tool. A dust collector is coupled to and supported by the power tool. The dust collector includes a motor, a suction fan driven by the motor, and a dust container. A vacuum drill bit is also coupled to the power tool. The vacuum drill bit includes an internal passageway that is in fluid communication with the dust container of the dust collector.

An electric power tool dust collection system includes: a hammer drill, to which a dust suction bit is mounted; a dust collection device mounted to the hammer drill and including a suction portion (introduction port), a dust collection motor, a dust collection fan rotated by drive of the dust collection motor to generate a sucking force in the introduction port, and a dust collection portion (dust box) that stores powder dust suctioned from the introduction port; and exhaust flow paths (exhaust flow path and tubular flow path) respectively formed in the hammer drill and the dust collection device to lead exhaust that has passed through the dust box to a high-temperature portion (output portion) of the hammer drill.

A dust collecting system includes a power tool and a dust collector. The dust collector includes a body, a sliding part, a biasing member, a lock member and an actuator. The body is configured to be removably attached to the power tool. The sliding part is held by the body so as to be slidable along a sliding axis. The biasing member is configured to bias the sliding part forward to hold the sliding part in a first position. The lock member is configured to lock the sliding part relative to the body in a second position. The actuator is configured to unlock the sliding part locked by the lock member, by operating in response to a motor-starting operation for the power tool by a user.

The hole saw dust collection device comprises a dust cover, an inner hole cutter, an outer hole cutter, a plurality of motion transfer rollers, and a hand crank handle. The hole saw dust collection device may saw a rectangular hole in a target surface using the outer hole cutter. The outer hole cutter may be directed along a rectangular path inside of the dust cover by a plurality of outer rollers. Rotation of the inner hole cutter may be transferred to the outer hole cutter via contact between the inner hole cutter, a plurality of inner rollers, the plurality of outer rollers, and the outer hole cutter. Saw dust produced by cutting the target surface may be suctioned from the interior of the dust cover by a vacuum cleaner that is coupled to the dust cover.

An assembly for controlling waste material during a hybrid subtractive and additive manufacturing process is disclosed, including a machining tool held in a holder, a shroud disposed around the machining tool, and one or more ports configured to create a negative pressure within the shroud. A method of constraining waste material during a hybrid subtractive and additive manufacturing process of a part includes adding an amount of material to a part being additively manufactured, transforming the amount of material that was added, manipulating a tool to machine a portion of the part being additively manufactured and generating a waste material, sealing a portion of the tool and covering a portion of the part with a shroud, and applying a negative pressure to create an airflow to prevent the waste material from exiting the shroud.

A debris control apparatus comprising a debris control enclosure, the enclosure further comprising a vacuum opening in the enclosure. The vacuum opening being sized, shaped and positioned to receiving a vacuum conduit, connected to a vacuum source, for extracting the debris from the enclosure. The debris control apparatus further comprising a mounting assembly for mounting the enclosure to a machine, such that, during operation, the enclosure moves along the work material as the cutting tool moves along the work material, the enclosure being mounted independent of movement of the cutting tool in and out of the work material. The mounting assembly comprises a depth adjuster for adjusting the operating depth of the enclosure. The depth of the enclosure can be adjusted such that the debris will be contained in the enclosure during operation.

A removable dust collection apparatus, in particular a removable dust collection container, for a hand-held power tool, includes at least one basic structure, which has at least one frame for receiving a form-variable collection bag or itself delimits a collection volume at least in part. The basic structure has at least one connecting piece for connection to a blow-out connector of the hand-held power tool, the connecting piece configuring the basic structure to be removably arranged on the hand-held power tool. The dust collection apparatus further includes at least one communication unit, which is in particular wireless, for exchanging in particular electronic data with at least one external unit, in particular the hand-held power tool or a mobile communication device.
