What you actually did was counterbore for the end of the bolt, not countersink. Also, it is usually referred to as a center drill, not a center drill bit. Most machinists will refer to "drill bits" as twist drills. And having worked with contractors quite a bit, they will call a handheld power drill a drill motor. I never asked but I think it is to differentiate it from a drill (twist drill) that will be chucked up in it. I always learn something from you. You have some unique ways to solve simple problems.
