Abstract: A well tool for removing metal debris from a well bore has a magnet element, an anti-torque anchor, a debris removal unit, a debris container and a first connecting end for a rotatable well string. The magnet element has a cylinder-shaped housing. The removal unit has a helix-shaped longitudinal guide element arranged on the housing. The anchor is connected to the housing or the guide element such that actuation of the anchor during use will prevent rotation of the housing or the guide element, respectively, relative the well-bore. The container has an opening at the end of the housing. The housing and the guide element are rotatable relative each other, and configured such that metal debris accumulating on the housing during use is guided by the guide element towards the opening of the container when the anchor is actuated and the first connecting end is rotated.
