A drilling device includes a drill basic body and a conveying helix which runs helically around the drill basic body. The conveying helix is subdivided into a plurality of conveying helix segments that are disposed next to one another. The conveying helix segments may be disposed loosely next to one another.

Drilling device

The A hand-held power tool includes a tool holderfor holding a tool and a pneumatic striking mechanism for periodically generating impacts on the tool held in the tool holder. The striking mechanism includes a guiding tube, an exciter piston, a striker, a pneumatic chamber closed by the exciter piston and the striker in the guiding tube, and a compensating opening in the guiding tube for ventilating the pneumatic chamber. A cap covers the compensating opening on an outside of the guiding tube. The cap is open in an opening direction which is largely tangential to the guiding tube.

Hand-held power tool

A machine tool includes a tool holder and a pneumatic striking mechanism that includes, on a working axis, an exciter piston, a beater, and a pneumatic chamber disposed between the exciter piston and the beater. The exciter piston is drivable by the motor and includes a pot-shaped base body, a seal ring, and a tube-shaped cladding body. The pot-shaped base body has a lateral wall enclosing the working axis and a collar which protrudes in a radial direction. The tube-shaped cladding body is disposed on the pot-shaped base body surrounding the lateral wall. A groove is defined between the collar and the tube-shaped cladding body and the seal ring is disposed in the groove.

Hand-held machine tool

A hand-held power tool includes a housing (), and a tag-shaped identification element () mountable on the housing () so that it becomes visible on an outer side of the housing (), provided with an identification mark (), insertable in a receptacle () provided on the housing.
