How to Drill Into a Cement Patio


Drilling into a cement patio requires different tools than drilling into metal or wood. Standard drill bits will not cut through cured cement, and a standard drill motor does not have the ability to perform multiple holes in a timely manner. To drill into the concrete you will need drill bits specially designed for masonry work and a hammer drill to propel the drill bit into the cement.

Things You'll Need

  • Variable-speed hammer drill
  • Carbide-tipped masonry drill bit
  • Electrical tape
  • Read the hammer drill owner's manual to determine how to secure the masonry bit into the chuck of the hammer drill.

  • Insert the carbide-tipped masonry drill bit into the hammer drill. Make sure that the hammer drill is set to hammer and not rotary.

  • Set the depth gauge located on the outside of the hammer drill to the depth of the hole you require in the cement patio. If your hammer drill does not have a depth gauge, wrap electrical tape around the drill bit to mark the depth of the hole.

  • Place the tip of the carbide-tipped drill bit against the surface of the cement patio, where you require the hole.

  • Slowly depress the trigger of the hammer drill to start drilling into the cement patio. Fully engage the trigger after the carbide-tipped drill bit has entered 1/8" into the surface of the patio.

  • Stop applying pressure to the drill when the depth gauge or the electrical tape contacts the surface of the cement.

  • Keep the carbide drill bit rotating as you pull the hammer drill away from the cement.

  • Release the trigger of the hammer drill after the drill bit is clear of the hole in the cement patio.
