How to Drill Into Block Walls


Concrete or cement blocks create resilient home foundations for long-term durability. However, they are tricky to drill into. A normal drill bit snaps in half if you try to use it on a block wall. To hang pictures or anchor something to a block wall, you need a special drill bits designed for tough masonry surfaces. The right drill bit and technique ensures a crisp, professional hole for your basement or garage project.

Things You'll Need

  • Chalk
  • Masonry drill bit
  • Electric drill
  • Compressed air
  • Mark the drilling spot on the wall with chalk.

  • Remove the existing bit from your electric drill. To loosen and remove the bit, turn the drill's circular ring near the bit counterclockwise.

  • Insert a masonry drill bit into the drill. The drill bit slides into the opening near the drill's nose.

  • Turn the circular ring near the bit clockwise to tighten it.

  • Adjust the drill's setting to low if possible. Some drills do not have speed settings. If you have the option to control the speed, it's best to use a lower setting on concrete or cement blocks.

  • Place the drill bit on the chalk mark, angling the bit slightly downward. An angled hole won't drip adhesive if you need to glue a bolt or nail into the drilled hole.

  • Press the drill's trigger and apply pressure toward the wall. The drill will start entering the wall, chipping away fine pieces of concrete dust.

  • Remove the drill from the hole two or three times as you drill, blowing into the hole to remove excess concrete dust. Do not let go of the trigger until the bit is removed from the wall. It is easier to back a drill out of the hole while the bit is still spinning.

  • Blow into the hole to remove remaining dust after you finish drilling. For best results, use a can of compressed air.
