Which drill do you need to drill in concrete?
Which drill do you need?
If you want to drill into hard materials like concrete, you need a drill with a hammer function. Without this function, you can't drill holes into concrete. There are 2 types of drills that have a hammer function: a hammer drill and a combi hammer. The impact function of an impact drill is similar to a hammer function, but it's much less powerful. That's why you can't use an impact drill for drilling into concrete.
Which impact power do you need?
Hammer drills and combi hammers have an impact power. You measure this impact power in energy (Joules). The larger the hole you want to drill into concrete, the more Joules the drill needs. Do you want to drill holes smaller than 20mm into concrete? Up to 2J is enough. For 21 to 24mm holes, you need 2 to 3J. Are you going to drill 25mm holes or larger? Use a drill with a 3J impact power or more.
Which drill bit do you need?
In addition to a drill or combi hammer, you also need the right drill bit. Hammer drills and combi hammers have an SDS plus or SDS max drill chuck. With this system, you can click your drill bit into the shaft so it doesn't slip away while drilling. Keep in mind that you buy a drill bit that fits into your drill chuck. An SDS plus drill bit doesn't fit into an SDS max drill chuck and the other way around. It's also important that you choose a concrete drill bit.
Conclusion
Thanks to the hammer function, you can drill into concrete with a hammer drill or combi hammer. Do you want to take on heavy drill jobs without problems? Choose a drill or combi hammer with at least 3J impact power. It's also important that you choose a concrete drill bit that has the same connector as your SDS plus or SDS max drill chuck.
