| Description: | 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. A secondary benefit to mag drills is they can drill and tap (thread) holes up to 1-5/8? (40mm). For example a common application is to drill a 9/16” (14mm) diameter hole to tap a 5/8? (16mm) thread without moving the machine. Electric magnetic drill presses which are best in most job site situations where electricity is readily available and the work environment is relatively dry. Pneumatic magnetic drill presses where a compressor can be accessed and the job site may be wet or in a hazardous environment. Hydraulic magnetic drill presses which are mainly used for for industrial, construction, and marine drilling applications. The material base to be used must be ferrous metal for the electromagnet to work The steel has to be flat and reasonably clean or the magnet won’t hold onto the surface. Make sure the bottom of the drill is also free from debris. Use a SAFETY chain to secure the drill press because once the power goes out, the tool will let loose of the steel and drop if overhead. |
