The swivel attachment on the screwdriver deserves a special respect for the creators. After all, they have made a really useful thing. Imagine, now you no longer need to remove the drill bit after drilling a hole, insert the bit for screwing in self-drilling screws and waste time on fixing. It is enough just to turn the nozzle and you have everything ready. The design is simple, but extremely ingenious. The nozzle itself comes with 8 Phillips and 8 flat bits, as well as 2 drill bits, an Allen wrench and a plastic storage case.
