Eagle Tool Company’s sheet metal installation tool lets you pre-drill holes and drive hex head metal screws without changing bits. They build a hex driver socket into the tip of a sliding barrel, so when the barrel is locked in the forward position you can drive screws and when you twist the barrel and slide it back you can drill.
Eagle Tools hardens the hex drive socket to make it durable and they claim the tool’s quick change shank fits most quick change drivers, which means the shank must be 1/4″ hex. When you break the drill bit, you can buy a kit that comes with three replacement drill bits, an Allen wrench, and three replacement set screws.
Eagle sells installation tools both for 1/4″ and 5/16″hex head screws. I can’t find either tool for sale anywhere on the web and they don’t list retail pricing on the site, but I can confirm I saw the 1/4″ driver on sale at Menards for a little more than $10.
