The dust produced when drilling & grinding some minerals can cause serious lung disease.

What are the main health hazards associated with breathing in quartz silica?

In general, high concentrations of dust may cause coughing and mild, temporary irritation following a short-term exposure. There is no human or animal information available specifically for quartz. Quartz can have potentially serious respiratory effects following long-term inhalation (one year or more).
