Abstract: A dust suction device for detachable attachment to a hand-held drilling machine includes a housing, a telescoping suction pipe coupled to the housing, an electric motor positioned in the housing, a suction fan driven by the electric motor and operable to generate a vacuum in the suction pipe, a dust collection container coupled to the housing and positioned upstream of the suction fan, and a support frame. The support frame includes a first portion coupled to the housing, a second portion coupled to a neck of the drilling machine, and an auxiliary handle extending from one of the first and second portions of the support frame. The support frame supports the drilling machine in a side-by-side relationship with the dust suction device.

Abstract: A hammer drill has an electric drive motor having a motor shaft and a tool shaft driven in rotation by the electric drive motor. A hammer action is provided. The tool shaft is driven by a first single-stage gear unit directly by the motor shaft of the electric drive motor. The hammer action is driven by a second single-stage gear unit directly by the motor shaft of the electric drive motor.

Abstract: A spindle sleeve (4) is provided for the rotary operation in a tool changing device on a hand-operated machine tool, especially a drill hammer for optional operation with a hammer drill or with another tool. To make rapid tool change possible with a simple design, a locking body (7), which co-rotates with the spindle sleeve (4), is mounted in at least one perforation (6) of the spindle sleeve (4). An adapter (14), on which the corresponding tool can be fixed, can be axially inserted into the spindle sleeve (4) with a guide surface (22, 23), and has depressions (13) for the locking bodies (7) for nonrotatable and axially nondisplaceable connection to the spindle sleeve (4). An outer sleeve (8), which blocks the locking bodies (7) in the depressions (13) in a locking position and radially releases them in its release position, is displaceably arranged on the spindle sleeve (4).
