Many thread sizes have several possible tap drills, because they yield threads of varying thread depth between 50% and 100%. Usually thread depths of 60% to 75% are desired. People frequently use a chart such as this to determine the proper tap drill for a certain thread size or the proper tap for an existing hole.

Eventually, simple mechanisms were created that let a person simply push at a pedal and keep the wheel turning at an even more constant rate.
