Should I use water when drilling concrete?

Though you don’t need to water down the concrete, the water will help to collect and remove the drilling dust, which can be hazardous to your health and “clog” the drill bit. The water can also help to keep your bit from overheating, which in turn helps keep the bit from shattering.
