Magnetic drills were initially designed for construction companies to drill a large quantity of holes in structural steel already in place, such as i-beams. They offer increased stability and are easier to use than a hand held drill and also provide better accuracy and cut large diameter holes faster, by using a magnetic drill, you’ll gain the precision and speed for drilling in tough materials when you need to drill with accuracy and consistency. Magnetic drills have a strong electromagnetic base enabling it to adhere to a carbon steel (ferrous metal) surface while turned on. Magnetic drills can be positioned to drill horizontally, vertically or overhead which is especially useful in construction.
