Drilling into brick or a concrete facade can be a challenging task. Unlike wood or plastic, masonry is much harder to bore a hole through. Also, you might encounter pockets of aggregate that can stall a project. Whether it's hanging pictures on a brick wall or creating a paver-based walkway, here are some easy steps for drilling a hole into concrete.
What you'll need:
Step 1: Wear proper gear.
Before this project, put on safety goggles and a dust mask to protect you from debris. Earplugs are also essential to block out loud noises while drilling.
Step 2: Mark the drill bit and concrete
An advanced drill might have a depth gauge to determine how far to drill. If your hammer drill doesn't have a gauge, wrap a piece of masking tape around the masonry bit to mark how deep you'll need to drill. Next, use chalk or a pencil to mark the spot you're drilling to ensure a clean and accurate hole through the brick or concrete facade.
Step 3: Drill slowly.
Line up the tip of the bit with the mark, but don’t put all your weight on the rotary hammer or hammer drill. Make sure to drill in small bursts or at a low drilling speed so the bit doesn't bind up and slow down the process. Allow the device to do the work while keeping a firm grip.
Step 4: Cool the drill down.
Back the rotary hammer or hammer drill out frequently while boring the hole so it cools off. Stop drilling once you've reached the desired depth.
Step 5: Break up any blockage.
If you stall while at any point while drilling, a chunk of aggregate rock could be in the way. Remove the drill and hammer in a masonry nail to break up the blockage. Try not to drive the masonry nail too deeply so that it's not too difficult to remove.
Step 6: Remove excess concrete dust.
When you're done drilling, use an air compressor to clean out any debris and concrete dust from the hole. Once the hole is clean, it should be ready for a screw or anchor.
