How to Drill Into Wall Correctly

Drilling into a wall seems simple — until you hit a pipe, crack the drywall, or end up with a hole in the wrong spot. This guide walks you through how to drill into a wall correctly, safely, and cleanly, whether you're hanging art, mounting shelves, or installing fixtures.

Before You Drill: Know What's Inside Your Wall

Walls contain hidden hazards: electrical wires, plumbing pipes, and structural studs. Always check before drilling:

Use a stud finder to locate studs and avoid hollow spots or hidden wiring. The 5-in-1 Stud Finder Wall Scanner detects wood, metal, AC wires, and pipes. Check it on Amazon →
Avoid drilling near outlets, switches, or plumbing fixtures.
When in doubt, use a non-contact voltage tester near the area first.

What You'll Need

Correct drill bit for your wall type (see below)
Pencil and tape measure
Safety goggles — DEWALT DPG84 →
Wall anchors (if not drilling into a stud)

Choosing the Right Bit for Your Wall Type

Drywall: Standard twist bit or drywall bit
Plaster: Sharp twist bit, go slow

Step-by-Step: How to Drill Into a Wall

Mark your spot precisely with a pencil. Use a level to ensure it's straight.
Scan the wall with a stud finder to check for studs, wires, and pipes.
Choose your anchor strategy: Drill into a stud for heavy loads; use a wall anchor for drywall between studs.
Put on safety goggles before drilling.
Start with a small pilot hole if drilling a large hole — this improves accuracy.
Hold the drill perpendicular to the wall and start at low speed.
Increase speed gradually and apply steady, moderate pressure.
Stop at the right depth — use tape on the bit as a depth marker.
Clear dust from the hole before inserting anchors or screws.

Drilling Into Drywall vs. Stud

Into a stud: Drill directly and drive your screw — no anchor needed. Studs support heavy loads like shelves and TVs.

Between studs (drywall only): Use a wall anchor rated for your load. Toggle bolts work for heavier items; plastic expansion anchors for lighter ones.

Safety Tips

Always wear safety goggles — drywall dust and debris fly back at you
Never drill near electrical panels or plumbing without professional guidance
Keep the drill perpendicular to avoid enlarging the hole
Don't drill too deep — you could hit wiring on the other side

Common Mistakes to Avoid

Skipping the stud finder scan
Using the wrong bit for the wall material
Drilling at an angle
Not using anchors in hollow drywall
Drilling too fast and cracking plaster or tile
