★【CONVERTS ANY ELECTRIC DRILL INTO A POWERFUL SCREWGUN】 - ¼ quick-change shank is designed to work with POWER DRILLS or HAND DRILLS, and reduces slipping in standard drill chucks (max. 2450 RPM)

★【THE SCREWDRIVER BIT IS REMOVABLE AND REPLACABLE】 - No need to replace the entire tool, most standard 1/4 hex 1" bits fit in. 4pcs of 1" Phillips #2 REAL IMPACT BITS come in the package. These bits are MAGNETIZED and easy to work with. Manganese Phosphate Coated bits offer excellent wear resistance and they are corrosion proof even in humid climates.

★【BUILD-IN CLUTCH】 disengages from drive-in function while reaching the workpiece. line up the screw, put this driver on the screw, then start drilling. It'll click when it reaches the depth, but if you lift off now it'll strip the screw a little. Instead, let the drill stop, then lift. The clutch is position sensitive, so it disengages when it hits the wood, but reengages when you lift off. Takes a couple tries to get used to, but not complicated

★【TO AVOID WOBBLING OF THE SCREWDRIVER BIT】, C-ring built inside of the chuck holds the bit tightly. Please use pliers to pull off the bit if it needs to be replaced.

★【EASY DEPTH ADJUSTEMENT】 - Set drywall, plywood and deck screws just right for depth. Enables to sufficiently countersink and counterbore screw heads precisely into any panel products. Depth adjustment works very easily and precisely with two threaded aluminum collars, main collar works as a stopper and the locknut collar as friction lock. (Stopper collar may leave a circular mark on the piece being worked on so it is recommended to work primarily on unfinished surfaces with screw setter tools)
