In the beginning, magnetic drills were developed specifically for use in the construction industry by companies that needed to make a huge number of holes in preexisting structural steel, such as I-beams. They give higher stability, are simpler to wield, and are easier to operate than a handheld drill. In addition, they provide improved precision and cut big diameter holes more quickly.

When you need to drill with accuracy and consistency, employing a magnetic drill can provide you with the precision and speed for drilling in tough materials that you require. Magnetic drills have a powerful electromagnetic basis that enables them to stick to the surface of carbon steel (or another ferrous metal) while the drill is turned on. If you purchase Magnetic drills from trusted brands such as Rotabroach, they have the capability of drilling in a horizontal, vertical, or above direction, making them very helpful in the construction industry.
Step By Step Guide For Using a Magnetic Drill

  • First of all, choose the appropriate drill bit for the material that has to be drilled. Determine the ejector pin to use based on the length of the cutter. 
  • Put the cutter into the machine’s chuck, then make sure the screws are in the right places. Then, move the machine in the direction of the mark that will serve as the location of the hole to be drilled. With the assistance of the pilot pin, locate the mark by placing the pointy end of the pilot pin above the mark.
  • After you have positioned the machine so that it is resting on the mark that will serve as the location of the hole, turn on the magnet switch that is located on the magnetic drilling machine. Check to see if the indicator for the magnet is glowing green. When the red light on the magnet indicator comes on, it indicates that there is not enough material below the magnet for it to have a perfect adhesion. In a perfect scenario, the minimum thickness of the material that is to be drilled is required to be 8 millimeters (5/16 inches).
  • Lubricant should be poured into the coolant tank. Never operate the equipment without first applying some lubricant. The magnetic drill press has a knob for the coolant tank; turn it so that it is ON. When drilling with annular cutters, you are required to apply the internal lubrication, and you must also use the exterior lubrication when drilling through a thickness of more than 50 millimeters.
  • After that start drilling with a slow feed rate after turning on the motor switch of the magnetic drill press. Avoid slamming the cutter down onto the material in an accidental manner. Begin drilling with a constant and consistent feed rate. The annular cutter cannot withstand a feed rate that is either too slow or too quick. Post that, examine the lubricant to see if it is leaking out. When you want good results, use a lot of lube.
  • If you apply an excessive amount of pressure to the feed handle, the drilling process will not go more quickly; instead, the annular cutters will be damaged. While Drilling with less pressure and a consistent feed will produce the greatest results and extend the annular cutters’ useful life. When cutting deep holes, you should utilize the reverse feed setting so that you don’t end up with long chips.
  • After you’ve finished drilling, make sure to clean the workspace with the proper equipment so that accidents don’t happen. Following the directions presented above will result in holes that are correctly finished, will take less time to complete, and will extend the useful life of the cutter as well as the machine.
