Drilling into brick is one of the most common DIY jobs — and also one of the easiest to get wrong.
Most problems happen because people use the wrong drill bit or expect the drill to do all the work.
Here’s how to choose the right tool and avoid turning a simple hole into a mess.
The Short Answer
You’ll need:
- A cordless drill
- Masonry drill bits
- Hammer mode (sometimes)
Brick is softer than concrete, but harder than plasterboard — the approach matters.
Choosing the Right Drill Bit
Brick requires masonry drill bits. These have a hardened tip designed to grind through masonry.
Important points:
- Wood or metal bits won’t work
- Blunt masonry bits struggle quickly
- Bit size should match the wall plug exactly
A good bit makes more difference than a powerful drill.
Do You Need Hammer Mode?
Not always.
- For soft brick, normal drill mode often works
- For harder brick or deeper holes, hammer mode helps
Start without hammer mode and only switch it on if progress slows.
How Fast Should You Drill?
- Start slowly to keep the hole straight
- Increase speed once the bit bites
- Don’t force the drill — steady pressure works best
If the drill stops cutting, pull it out and clear dust.
Common Mistakes to Avoid
- Using hammer mode immediately
- Drilling too close to the edge of a brick
- Guessing plug sizes
- Overheating the drill bit
Most cracked bricks are caused by rushing.
Final Thought
Brick drilling isn’t about strength.
It’s about using the right bit, at the right speed, with a bit of patience.
