Interesting concept but 50% saved time in the video is exaggeration - when you have 10 holes to drill and screw then just first drill 10 holes, change ending in your tool and then screw 10 holes. If you doing this whole day then have just 2 tools - you need this at least for backup if one tool breaks.
