Tense like when I almost took off the corner of my finger with the carbide bit? Not a problem! I only get dangerous with drills, like when I was installing fender flares and accidently bored a hole into my thumbnail with a phillips tip bit on my cordless when it slipped off the self tapping screw. It didnt hurt much it got infected a few days later because a piece of the nail was driven in past the bone. Digging it out with tweezers, now THAT was fun!
