1. Introduction
This magnetic drill is designed for drilling holes in steel fabrication work. It is an ideal portable
drilling solution equally suited for use in building sites or the workshop environment and can be
used to cut in horizontal, vertical and overhead positions.
Power Cable
The magnetic drill uses an annular hole cutter (sometimes called a slugger bit) to cut clean and accurate holes
without pre-drilling or step drilling. After cutting through the steel the cutter produces a "slug" (a cylindrical
lump of steel) that falls from the centre of the cut.
