I find blowing through a fairly long straw the best way to clean dust out of a drilled hole in concrete. Just be prepared to protect your eyes as the dust really circulates everywhere if you blow vigorously enough to really clear the dust out of the hole.


My plan was to run the drill in, leave it in, and
blow while the drill is keeping the hole plugged.
