From the Manufacturer:
Sam Vick, a carpenter & building contractor, was looking for an easier way to install hinges, window latches & hardware using screws. He invented a self-centering drill bit that ensured a perfectly centered hole every time. The Vix-Bit became so popular with fellow carpenters that he formed S.E. Vick Tool Company in 1958.
