Types of Magnetic Drilling Machines

magnetic drill, mag drill for short, is a drill used to cut metal. Magnetic drills are made up from 4 key components: a magnetic base, a drill stand, a motor, and an arbor or chuck. You can use a wide variety of tooling with mag drills including annular cutters, twist drills, taps, reamers, and counter sinks. The convenience of a magnetic drill can’t be overstated.

Like the benchtop drill press or standing drill press, you need a magnetic drill press in hard to access locations, such as I-beams, truck beds, stationary vertical metal parts, etc. The magnetic base adheres to the metal surface and stabilizes the drill in order to cut the material. You won’t be able to achieve the same results with a non-magnetic drill press – don’t even try.

Why use a magnetic drilling machine?

By using a magnetic drill, you’ll get the precision and speed you need to drill in hard materials when you need to drill with precision and consistency. The magnetic drill has a powerful electromagnetic base that allows it to adhere to the surface of carbon steel (ferrous metals) when turned on. The magnetic drill can be positioned to drill horizontally, vertically or overhead, which is particularly useful in construction. Ensure that your magnetic drill is secured to the surface being drilled, especially if it is above your head, to avoid dropping or falling on your head from a height.


Types of magnetic drilling machines.

Electromagnetic drilling machines are best suited to most jobsite situations where electricity is available and the working environment is relatively dry.

Pneumatic magnetic drilling machines, which have access to a compressor and where the job site may be wet or in a hazardous environment.

Hydraulic magnetic drilling machines are mainly used for industrial, construction and offshore drilling applications.

How to use the magnetic drilling machine?

The material base to be used must be ferrous in order for the solenoid to work

The steel must be flat and fairly clean otherwise the magnet will not hold on to the surface

Make sure the bottom of the drill is also free of debris.

Use a safety chain to hold the drill press in place as the tool will come loose from the steel and fall over the head in the event of a power failure.


Cutting Tools for Magnetic Drills:

Most often you’ll use an annular cutter when drilling through steel. An annular cutter is an end mill with a hollow center that cuts holes in the metal. For annular cutters to work best, the steel generally needs to be at least 1/4″ thick for the magnetic drill press to stick to the surface – 1/2″ steel better.


Core Cutting with a Magnetic Drill Press

When cutting or drilling holes in steel, the magnetic drill press is indespensible. You can line up your drill and secure it in place which will take the wear and tear off your body while drilling. If you have the budget, get a mag drill with a swivel base. This makes lining up the drill over the hole easier.
