I guess I kind of fall in to this topic. My Father-in-law recently bought a collection of Dewalt stuff at a garage sale and he gave me an impact driver. The label on the handle is DW056, but it has a 1/2" drive on it. Any way I can convert it back to the stock chuck so I can use regular screwdriver bits or am I better off just sticking to some 1/2" drive screwdriver bits like these?
