A Beginner’s Guide to Drilling into Any Wall Safely

Drilling into a wall can feel intimidating - from identifying the wall type and navigating hidden pipes or wires to knowing which drill setting or drill bit to choose, it’s no surprise that a recent poll found a quarter of homeowners put this DIY job off altogether.

Fortunately, we've teamed up with expert Jasmine Gurney to de-bunk common fears surrounding DIY sticking points including drilling into walls. Her beginners guide will help you to tackle your next home project with confidence, and without any unwanted surprises.

Step 1: Identify Your Wall Type Before You Drill

Before picking up a drill, the most important step is understanding what kind of wall you’re working with. Different wall types need different drill bits, settings and fixings.

Try the simple knock test:

  • Hollow sound? You’re likely working with plasterboard
  • Solid or dense sound? This usually means brick or blockwork

This quick check helps you avoid using the wrong drill setting and reduces the risk of damage.
 

Step 2: Choose the Right Drill and Settings

Using the correct drill settings is just as important as the drill itself.

A versatile cordless drill, like a two-gear hammer drill, gives you flexibility for different materials:

  • Gear 1: More control, ideal for driving screws or starting holes
  • Gear 2: Faster drilling for harder surfaces
  • Hammer mode: Extra power for tough materials like brick or concrete

Top tip: Hammer mode should never be used on plasterboard, wood or metal studs - it can cause cracking and unnecessary damage.
 

Step 3: Use the Correct Drill Bit for the Job

Matching your drill bit to your wall type is essential for clean, safe results.

  • Brick, concrete or dot-and-dab walls: Use a masonry bit with hammer mode switched on
  • Plasterboard or wood: Use a wood or multipurpose bit with standard drill mode
  • Metal studs: Use an HSS bit and make sure hammer mode is turned off

For lighter materials like wood, plastic or thin metal, a cordless drill driver is often all you need.
 

Step 4: Check for Hidden Pipes and Wires

One of the biggest DIY fears is drilling into something you shouldn’t and it’s a valid concern.

Before drilling:

  1. Scan the area using a stud or wall sensor
  2. Mark your safe spot with a pencil
  3. Scan again to double-check

Taking an extra minute to scan properly can save you from costly repairs later.
 

Step 5: Drill Safely and Let the Tool Do the Work

When you’re ready to drill:

  • Hold the drill straight
  • Start slowly
  • Apply steady pressure, never force it

If the drill is struggling, stop and reassess. Forcing the drill can cause slipping, cracking or damage to the wall.
 

Step 6: Don’t Forget the Wall Plugs

Wall plugs might be small, but they make a big difference.

Always use:

  • The correct wall plug for your wall type
  • The right size plug for your screw

This ensures a secure fixing and helps prevent shelves, frames or fixtures from coming loose over time.

Once you understand your wall type, drill settings and fixings, DIY becomes far less daunting. With the right preparation and tools, you can take on everything from hanging pictures to installing shelving safely and confidently.
