The auto-feed attachment on the DS325AC and DS340AC corded screwdrivers removes the need for individual loading of fasteners. A feed on return function moves each screw into place before driving. Both systems are compatible with fasteners between 5/8 in. and 3 in. in size. One- or two-handed operation is possible thanks to a cushioned second hand grip. Both models come with a detachable 21 in. extension pole for standing applications.
