Drilling into concrete can seem daunting, but with the right tools and preparation, it’s a straightforward task—even for beginners. Understanding which equipment to use and how to approach the job will help you drill clean, accurate holes without damaging your tools or wasting time.
Using the correct drill and masonry bits is essential. The wrong setup can slow progress, wear out equipment and produce poor results. This guide explains what you need to know before you start.
Safety essentials
Concrete drilling produces significant dust and noise, so proper safety gear is important. Always wear eye protection to guard against abrasive dust and debris. Gloves improve grip and protect your hands, while a dust mask helps prevent inhaling fine particles—especially when working indoors or overhead.
If possible, ventilate the area by opening windows and moving nearby items out of the way. Ear protection is also advisable, particularly for longer jobs or when using powerful drills.
Choosing the right drill and bits
The type of concrete and the job size determine the tools you’ll need. For most household tasks, a combi drill is sufficient. Harder or reinforced concrete may require a drill with a hammer or percussion function, designed specifically for masonry.
Use masonry drill bits with carbide tips for best results. Common sizes such as 5mm, 6mm and 8mm cover most household fixings. Keep spare bits available, as concrete can dull them quickly. Once holes are drilled, use suitable fixings or screws; a combi drill usually handles this, though a more powerful driver can speed up larger projects.
Checks before drilling
Before you start, confirm what you’re drilling into and the required depth. Be aware of structural elements like lintels, and always check for hidden pipes or electrical cables. A cable and pipe detector is a small investment that can prevent serious damage or safety risks.
Step-by-step guide
-
Mark the hole: Use a pencil to mark the drilling point. A centre punch creates a small indent to prevent the bit from slipping.
-
Set the depth: Use a depth stop or tape on the drill bit to ensure accurate drilling depth.
-
Drill a pilot hole: Start with a smaller bit to make drilling easier and reduce strain on the drill.
-
Drill steadily: Begin slowly, then increase speed and pressure gradually. Avoid forcing the drill—let it do the work. Remove the bit occasionally to clear dust and ensure better fixing grip.
