Third, it’s important to maintain a steady pressure when drilling and prevent the bit from slipping or overheating, as both can lead to cracking.įourth, drill slowly and use a light touch when pulling the bit out of the hole.įinally, you can use a concrete sealer after you’ve finished drilling to extend the life of the hole and prevent it from cracking.įollowing these steps can help you drill a hole in concrete without cracking it. Second, increase the speed of the drill and apply lubrication, such as water, to the drill bit to reduce friction. Carbide-tipped masonry drill bits are the best for drilling into concrete make sure the bit size matches the size of the hole you are drilling. However, there are steps you can take to reduce the risk of cracking the concrete when drilling a hole.įirst, use the appropriate drill bit for the job. How do you drill a hole in concrete without cracking it?ĭrilling a hole in concrete can be challenging, as it is a relatively brittle material. You should also use a core bit or masonry bit whenever possible to prevent damage to the surrounding concrete.Īdditionally, you should use an impact- and vibration-resistant concrete mixture when pouring new concrete or concrete patching to help reduce the chances of cracking. When drilling, proceed slowly and only drill deep enough to accommodate the screws, plugs, or anchors that you are using. To avoid this, you should use a hammer drill or masonry bit.

Drilling into concrete can also cause damage to the surface, which can make it more vulnerable to cracking in the future. The cracks may be small and not very noticeable, but this is normal since concrete is very hard and brittle. Yes, drilling into concrete can cause it to crack.
