Abstract: A dust extractor for a drill is provided, including a single air flow path, a shroud having an internal chamber for collecting dust in fluid communication with a first end of the single air flow path, a filter assembly located in the single air flow path, a vacuum source connected to a second end of the single air flow path, and an air flow control mechanism controlling a direction of air flow generated by the vacuum source. During a normal operation, the vacuum source draws air and entrained debris from the internal chamber of the shroud through the single air flow path. During a back flush operation, the vacuum source blows air and entrained debris through the single air flow path towards the shroud. The air passes through the filter assembly to remove the entrained debris in either direction.

Abstract: A dust extractor is provided including a main housing, a telescopic tubular extension arm comprising a first forward section slidable into or out of a second rear section over a stroke length between a first inner position and a second outer position, the second rear section being mounted onto the main housing, a shroud mounted on one end of the first forward section remote from the second rear section, a biasing force arranged to urge the first forward section to slide out of the second rear section towards the second outer position, and a dust collection box mounted on the main housing. The stroke length of the telescopic extension arm is greater than 150 mm.

Abstract: A suction cup dust extractor for a power tool is provided. The dust extractor includes a housing; a drill collar attached to the housing and having a drill passage formed through it; a suction chamber formed by the walls of the housing having an opening and which, in use, locates against a work piece to create a chamber; a single aperture located on the housing through which air can pass; at least one first air passage formed by the walls of the housing that connects between the drill passage and the aperture to enable air to pass from the drill passage to the aperture; and at least one second air passage formed within the housing that connects between the suction chamber and the single aperture and enables air to pass from the suction chamber to the aperture. A part of the first air passage is formed by a tube.

Abstract: A drill has a housing, a motor mounted in the housing having a drive spindle, an output spindle rotationally driven by the drive spindle via a torque clutch. The torque clutch slips when the torque across the torque clutch exceeds a predetermined value. The predetermined value of the torque at which the torque clutch starts to slip is adjustable via a torque threshold adjustment mechanism. A sleeve is rotatably mounted on the output spindle. The drive spindle drives the sleeve via a gear system at a same rate and direction as the output spindle so that there is no relative rotation between the sleeve and output spindle when the torque clutch is not slipping and at a different rate and/or direction so that there is relative rotation between the sleeve and output spindle when the torque clutch is slipping.

Abstract: A planetary gear system with a sun gear, a ring gear co-axial with the sun gear, at least one planetary gear meshing with both the sun gear and the ring gear, and a planetary gear carrier which rotationally supports the at least one planetary gear. A torque clutch is supported by and connected directly between two of the sun gear, the ring gear, the at least one planetary gear and the planetary gear carrier. The torque clutch prevents relative rotation when an acting torque is below a predetermined torque value and allows relative rotation when the acting torque is above the predetermined torque value. A torque threshold adjustment mechanism is provided for adjusting the predetermined value of the torque at which the torque clutch slips.
