Abstract: A hammer/drill includes a housing, a motor with armature shaft, a spindle rotatably mounted about a longitudinal axis in the housing, a tool holder rotatingly driven by the motor about the longitudinal axis, a hammer mechanism for generating impacts acting on the tool holder, a drive shaft coupleable with the armature shaft, and a switching arrangement to switch between drilling, hammer drilling, and hammering modes. The switching arrangement comprises a selector and coupling part axially displaceable on the drive shaft between lower and upper positions, coupling and decoupling the drive shaft to the armature shaft respectively. The coupling part includes a sleeve comprising a flange, and the selector comprises a fork for engaging a lower part of the flange. A protuberance engages a drive member of the selector to pivot the selector when the spindle is rotated, engaging over only a portion of the rotational movement of the spindle.

Abstract: A powered hammer includes a body in which is disposed a motor and a hammer mechanism driven by the motor when the motor is activated. A tool holder is coupled to a front portion of the body and which is capable of holding a cutting tool. The hammer mechanism, when driven by the motor, is capable of imparting impacts to a cutting tool, when held by the tool holder. A handle is moveably coupled to a rear portion of the body for movement toward and away from the body along a tool axis of the tool holder. The handle includes a grip portion and first and second end connection sections coupled to opposite end portions of the grip portion. The first and second end connection sections are slideably mounted on first and second arms that project rearward from the body. A movement control mechanism is mounted inside the handle and coupled to the first and second arms and the handle.
