Incorporates a smooth ergonomic grip and a removable bottom cap for extra bit storage, the patented ratcheting mechanism allows the ratchet to drive screws twice as fast. The driver's tip rotates in the same direction, regardless of where the torque is being applied from, allowing for continuous torque which helps to maximize. To achieve double efficiency, simply hold the collar and rotate the handle clockwise and counter clockwise. Convenient slider switch reverses direction. Includes (20) 1/2 in (4 mm) hex shank precision bits.
