AITA? I got into an argument with my friend and insulted him out of frustration.

I’m 25M and my friend is 26M. We were working together on a flooring project and I needed him to drill into the concrete, which is what I usually do but since I had other stuff to do I let him do it. I do have more work experience than he does as well. Since this is his first time doing this work. I demonstrated first on how to do it and then I walked him through on the second one. While demonstrating I told him while drilling into the concrete do not go in reverse. I told him a couple times and then I guided him through on the 2nd one. He ended up going in reverse and when he did I firmly grabbed his hand to stop him and told him to not go in reverse, he did it again and I firmly told him again to not do it. Well after the 2nd hole was done I told him that if he has any questions or simply anything to ask me. I told him twice and he said he understood. Well 5 minutes in and he broke my bit by going in reverse. I was upset and reminded him that I told him not to go in reverse. He said that when I told him he thought it was just a preference. Although I was stern when I told him to not go in reverse. His reasoning is if I had given him an explanation as to why he shouldn’t have gone in reverse then he wouldn’t have done it. However I told him that an explanation isn’t a valid reason to go against my word. I also felt very disrespected because I was super upset and he was trying to downplay it. We got into an argument about it. I feel like him going against my word is disrespectful, and him breaking it is avoiding accountability by shifting the blame on me for not explaining the reason. I did insult him a little as well by telling him that in the real world when someone tells you to not do something you shouldn’t do it and you’re not owed or expected a reason. A no is no. Am I in the right or is my friend in the right? Also am I the asshole for insulting him out of frustration by telling him how the ‘real’ world works.
