Although changing the bit out of a driver is not a complicated or difficult process, when you need to transition between bits often enough, the task becomes tiresome, to say the least. With this little innovation from Worx, however, instead of switching out your bit every time you need a different one, you can simply unlock the chuck and rotate it 180 degrees in order to swap between bits. Obviously, if you are using more than two, the same problem arises, but it will likely save some time/hassle in the long run. In addition, the concept itself could be applied toward adding more chuck heads (e.g. four-headed driver). Certainly, this is not a life-changing product, but it is a clever idea that could prove to be very practical.
