Wet/Dry Combo Core Bits

By Deb Amorde

Let’s start with the basics. What is a core bit? Simply, a core bit is a tube-shaped bit specifically designed to remove a cylinder of material. Removing the material (concrete as it applies here) can occur two ways, wet or dry, and the method you choose depends on your job’s application

Wet Core Drilling. As the name implies, wet core drilling requires a water source, usually a hose connecting directly to the drill. Pay attention to just how much water you’re adding. If there’s not enough, the slurry becomes past-like and will slow down the job. Aim for the consistency of creamed coffee. When done properly, this method is usually more efficient than dry core drilling

Dry Core Drilling. You guessed it, is core drilling without water. This method produces a lot of concrete dust which can be extremely harmful and is now regulated by dust containment laws. If dry core drilling is so bad, why do it? For many, it’s all they know. Another good reason to go this route is if you’re drilling could potentially put you in contact with electrical wires. There are a number of solutions for dry coring within dust regulations, such as vacuums and attachments which you can find here.
