Dry drilling of concrete.

Dry drilling of concrete. In situations where drilling must be done in finished interiors, using water is not allowed. Drilling has to be performed dry. Dry drilling is becoming increasingly popular because it does not create dirt at the worksite, making the process much more convenient by reducing cleanup time after the job and eliminating the need for water supply. Drill bits designed for wet drilling will not work in dry mode — special dry drilling bits are required.
