How to Drill Screws Into Concrete Wall
Outdoor accessories such as garden hose reels and equipment racks make outdoor living more efficient, but if your home's exterior is brick, you likely will need to install some of the attachments into the concrete mortar between bricks. You can use the same drilling techniques for attaching objects to interior concrete walls, such as those found in basements. Does this Spark an idea?

1
Select the proper size carbide-tipped masonry bit based on the manufacturer's instructions for your concrete screw fasteners. Secure the bit in a handheld drill.
-
2
Place a piece of masking tape around the bit at the depth the fastener will sit in the wall. If your drill has a depth gauge, use that instead.

Hold the drill perpendicular to the concrete and begin drilling the hole to the appropriate depth. Pull the drill out of the hole every 10 seconds in order to remove dust.

5
Blow the dust out of the hole with an air compressor or blow dryer, or vacuum the dust out of the hole.

6
Place a fastener in the hole, making sure that the outside rim sits flat against the concrete wall.

Drill any other necessary holes and attach your object to the wall with screws driven directly into the fasteners.

Tips & Warnings
If you have a lot of holes to drill, consider purchasing or renting a hammer drill. A hammer drill is more durable and can work for longer periods of time without overheating. If you reach a point where the drill refuses to push any further into the concrete, you have likely hit aggregate (rock). Place a masonry nail in the hole and hammer through the aggregate, then continue drilling.
Always wear safety glasses when using power tools.
