Depends on what is being done. If turning and milling, then nitrile (a great glove) glove might pose a danger if it is caught into the spinning work or tool. It won't just tear off, it will pull in the hand.
It is like long sleeves or long un-kept hair.
If you can be sure to be away from moving stuff - then ok. Or willing to take the risk.
I use them when I use chemicals or when I want to protect my hands in non-moving times.
