The Bit Shooter Screwdriver features a multi-bit screwdriver with a multi-cartridge speed loading system. Just spin and load, and get the right bit every time. With other multiple bit screwdriver systems the bits can fall out of the screwdriver, or can get lost in your toolbox or around your house. With the Bit Shooter all that becomes a thing of the past. The Bit Shooter screwdriver stores all the bits you need in magnetized speed loader cylinders.
