Klein Tools 3/16" tip x 6" Rapi-Driv Rotary Screwdriver with Cushion Grip Handle is a professional-grade tool. It features a unique crank action handle that spins screws with one hand, saving time and effort. The shank rotates in the handle, making it ideal for long threaded screws in switch plates, fixtures, and more. Simply place your thumb on the bend on the shaft to snug up the screw. The heavy-duty square shanks allow for wrench assisted turning, while the bolster reinforces the shank for hard use. The cushion-grip handles provide greater torque and comfort, even during extended use. Precision machined tips ensure an exact fit, while the "Tip-Ident" quickly identifies the screwdriver type and tip orientation. This screwdriver is POP Packaged for easy storage and retrieval.
