Not really, if you are well versed with the machine then it isn't dangerous. But if not you have to learn and read all the dos and don'ts before heading right in. One for sure has to be that you are wearing protective gear. Secondly, never try to make any adjustment while operating the machine. Next, keep track that you have no tools laying around on the table you are drilling on and don't dust away any shards with your bare hands. Before using a drill machine make sure to read the instructions and you are good to go.
