This looks simple enough: your 1/4″ insert bit goes in the tip, which then fits over your drill’s 3/8″ chuck so you can switch from drilling to driving in a hurry. But we’re a little dubious. Black & Decker though enough of the idea to manufacture drills with a removable chuck, but are these just more versions of the ever-infamous Dual Drill?
One positive note: the “chuck buddy” will set you back less than a buck. What do you think? Is this junk or a good idea? Let us know in comments.
