At some point in your do-it-yourself home maintenance career, you’ll probably be faced with a task that calls for drilling into concrete, and this guide will help to prepare you for the task. Below you’ll find a discussion on the process itself, as well as some of the tools you might use to accomplish the job.

Drilling procedure

  1. The first step you need to take is to measure and mark the spot on the masonry or concrete where you intend to drill. Make sure to check the infrastructure behind the concrete, so that you don’t damage anything important in that area. For instance, there may be water pipes, ductwork, or electrical wiring behind the concrete surface you’re drilling.
  2. Next you need to prepare your drill, and the first step in that process is to set your depth stop to 1/4 inch longer than the whole you intend to drill. If you drill doesn’t have a stop bar or a depth guide, you can accomplish the same thing by wrapping a piece of masking tape around the drill bit at the appropriate depth mark. Then, you should fit your drill with a carbide masonry bit of the appropriate size for the task. Make sure that before you start, you’ve outfitted yourself with gloves, ear protection, and a mask or safety goggles.
  3. Now you need to drill a guide hole, and to do this you’ll have to establish yourself with a good stable stance, having your feet shoulder-width apart. You should be able to grip a lightweight drill in one hand, and if the drill doesn’t have an auxiliary type of handle, you can use your non-grip hand to brace the drill. Next you can position the tip of your drill on the original mark you made on the concrete surface, and once you start drilling, make sure to keep the drill perpendicular to the surface.
  4. Start the drill at its lowest speed so that you’ll be able to control it, and then drill forward with a steady light pressure that doesn’t include forcing. Your guide hole should be drilled to a depth of about 1/4 inch, and then you can stop drilling to brush away the accumulated concrete dust. Now you’re ready to drill your actual hole. Put the drill back in the pilot hole, while maintaining your perpendicular position to the hole.
  5. Start the drill and press forward without using any excessive pressure, and continue to run the drill at a slow to medium speed. You should occasionally pull the drill out, so as to remove the concrete dust which tends to accumulate. If any obstructions are encountered, stop your drill right away and remove it from the hole. You can use a masonry nail and hammer to break up the object, but don’t drive the nail completely into it. Once you drill your hole to the correct depth, you can stop the drill and brush away any accumulated concrete dust.
