The Speed Driver is two screwdrivers in one that offers a high speed, low torque screwdriver operating at a speed of four turns of the screw for every one turn of the handle and a standard ratcheting screwdriver for high torque applications operating at a speed of one turn of the screw for every one turn of the handle. A patented switching mechanism offers on the fly switching between the 4:1 speed mode and the 1:1 standard mode.
