I find t very stable, after all you are only drilling through a piece of wood or plastic barely 4mm thick, before i purchased this i used to drill free hand with my Millwaukee cordless drill now being a carpenter by trade i like to think my arm and eye is fairly true, but in all honesty you know 100% when you use a drill press that your going to drill your hole at a true 90 degrees which can make a big difference when fitting your scales and linning up every thing.
