When I'm drilling holes for shield anchors for things that bolt into concrete floors or paving, there's usually at least two holes to drill, and every hole after the first tends to get gritty concrete dust down it, which makes the bolts seize up in the threads.
A bit of blue tack or chewing gum stuck over the top of each hole keeps the dust out effectively. (Don't resume chewing the gum after use).
