Abstract

A magnetic base for an electric power tool, in particular for a magnetic core drilling machine. The magnetic base having a base body that has a contact surface for contacting a workpiece to be machined, at least one first permanent magnet and at least one second permanent magnet arranged in the base body, the at least one and second permanent magnet having magnetic forces that interact to form a resulting holding force. The at least one first permanent magnet and the at least one second permanent magnet are supported in the base body and rotatable around its own rotation axis between a first position, in which the resulting holding force of the magnetic base is maximized, and a second position, in which the resulting holding force of the magnetic base is minimized.
