INTRO
You’ve marked the spot, lined up the drill, and then hesitated.
Brick feels solid - almost too solid - and it’s easy to worry that one wrong move will cause a crack, a blown edge, or a mess you can’t undo. That hesitation is completely normal.
The reassuring news is this: drilling into brick is actually very forgiving when done calmly. This guide shows you how to drill into brick without cracking it, even if you’ve never done it before.
Why brick cracks when drilled (and how to avoid it)
Brick usually cracks because of stress, not because it’s weak. The most common causes are:
- Pushing too hard
- Drilling too fast
- Letting the drill wobble
- Starting too close to an edge
A slow, controlled approach spreads the force evenly and keeps the brick intact.
Method 1: Drilling cleanly into brick (best for beginners)
Works for: Most household fixings
- Mark the drilling point clearly with a pencil.
- Use a masonry drill bit and keep the drill straight.
- Start at a slow speed with light pressure.
- Let the bit bite gradually — don’t force it.
- Pause every few seconds to clear brick dust.
Why this works: Brick cracks when heat and pressure build up. Slow drilling and short pauses reduce both.
Method 2: If the drill struggles or squeals
Slow down rather than pushing harder
If the drill feels like it’s slipping, squealing, or barely moving, resist the urge to lean into it.
- Reduce speed
- Pull the bit out slightly to clear dust
- Re-align the drill so it stays straight
Most cracking happens when pressure replaces patience.
Method 3: Drilling near brick edges or mortar
Extra care needed here
Brick edges are more fragile than the centre. If possible, drill into the mortar joint instead — it’s softer and easier to repair.
If you must drill into brick near an edge:
- Keep at least 20mm from the edge
- Drill extra slowly
- Avoid hammer mode at first
Common mistakes that cause cracks
- ❌ Starting at full speed
- ❌ Pushing hard to “get through quicker”
- ❌ Drilling at an angle
- ❌ Not clearing dust from the hole
FAQ
Q: Do I need hammer mode to drill into brick?
A: Often yes, but start without it. Once the hole is established, light hammer action can help — forcing it early is what causes cracks.
Q: Why is my brick cracking while drilling?
A: Usually from too much pressure or speed. Slowing down and letting the drill work naturally prevents stress fractures.
