Drilling into brick walls requires a specific type of drill bit called a masonry bit, which has a carbide tip designed to bore through tough materials like brick, concrete, and stone. Here are the steps to use a drill for brick walls:

1. Mark the spot where you want to drill the hole using a pencil or marker.
2. Attach the masonry bit to your drill and tighten it securely.
3. Put on safety goggles and a dust mask to protect yourself from flying debris.
4. Hold the drill perpendicular to the wall and apply steady pressure as you begin to drill.
5. Keep the drill bit lubricated with water or drilling oil to prevent overheating.
6. Once the bit has penetrated the surface of the brick, you can increase the speed of the drill to make the hole deeper.
7. Continue drilling until you have reached the desired depth.
8. When you’re finished, turn off the drill and remove the masonry bit.
9. Clean up any dust and debris from the hole and surrounding area.
