The revolver concept came about as Worx engineers were looking for a way to improve the design of the standard hand drill that has not changed for over 100 years. It was observed that the pistol grip design had some major flaws. The most important shortfall in the design is that no one actually holds the drill by the pistol grip. In order to apply force directly behind the drill bit, most experienced users hold the drill at the top and operate the trigger using their pinky finger. This can be very awkward for the user and create serious discomfort with prolonged use. The Revolver drill is the only drill available which places the trigger and the grip directly behind the drill bit axis. This means the user can apply proper force to the drill without having to hold the tool in a way in which it was not designed.
