Wet vs Dry - Choose the Right Core Drilling Tool

Choosing the right kind of core bits may not be obvious for everyone. Let us help.

Dry core bits, like the name suggests, can be used without water; while wet bits require water-cooling to operate. Using dry bits is convenient and more friendly to DIY users, but it is often not powerful enough to match the drilling power of wet core bits. Here we have put together a quick guideline to help you determine which bit to use depending on the target material, and equipment.


  • If you have no experience with diamond bit drilling, talk to a professional first
  • Make sure you are using appropriate protective gear, including eye and ear protection

    WE have to drill 2" diameter holes through an approx 12" thick concrete floor in a museum with a carpeted floor so wet drilling is impossible. Is a dry bit even possible or is it out of the question?
