Abstract

A magnetic base for an electric power tool, in particular for a magnetic core drilling machine. The magnetic base having a base body, in which at least one first solenoid coil forming an electromagnet is accommodated in a receiving space, whose magnetic force is switchable between a maximum resulting holding force and a minimum resulting holding force. A first side that is adapted to be coupled with the electric power tool. An oppositely situated second side, which is adapted to be placed on a workpiece to be processed. The receiving space is designed such that an insertion of the at least one solenoid coil into the receiving space is possible only from the first side.
