Running a dryer vent through a brick wall can be a little challenging. For homes that have siding as an exterior wall, all you need to do is use a hole saw to drill out your hole. For brick, to drill a circular hole you need a masonry core bit, which can be costly. However, there are other alternatives that allow you to cut out brick to install a dryer vent. These won't leave you with a perfectly clean-looking hole, but the hood of the dryer vent will cover up any imperfections.
Things you need
6 mm (1/4 inch) hammer drill bit
10.6 cm (4 1/4 inch) hole saw
Put on gloves, ear protection and safety glasses. Flying debris can cause serious injury to unprotected body parts.
Draw a 10.6 cm (4 1/4 inch) diameter circle on the brick wall where you want your dryer vent to come through the brick. Use permanent marker so that the circle remains visible throughout the process.
Insert a 6 mm (1/4 inch) hammer drill bit into your hammer drill. Drill through the brick along the permanent marker line. Drill a hole every 6 mm (1/2 inch) around the entire circle.
Place a chisel on the line and strike it with the hammer. Repeat this process slowly around the entire circle. After the brick circle becomes loose, remove it by hand.
Insert your 10.6 cm (4 1/4 inch) hole saw bit into your drill and finish drilling the hole through the wall. You'll be drilling through the exterior plywood layer. You should then see a clean hole to the interior of your home.
