Abstract
A drilling machine, in particular a magnetic core drilling machine. The drilling machine having a magnetic base to detachably secure the drilling machine to a surface. A drive motor is arranged in a housing and has a rotor shaft with a rotor shaft longitudinal axis that is connected in a power-transmitting manner via a gear mechanism to a tool spindle with a spindle longitudinal axis. A tool holder is connected to the tool spindle to receive a drilling tool. The spindle longitudinal axis is aligned substantially parallel to the longitudinal axis of the rotor shaft, and the tool spindle is axially adjusted along the longitudinal axis of the spindle relative to the drive motor and the magnetic base.
