I bought this set almost like an experiment. I wanted to use it with my c3 driver and find out some different uses for both. My best discovery was to use it to remove my car's lug bolts. It worked great! I have broken a couple regular sockets but the drivers are still great! I also use the two tools on my motorcycle. Best 5 bucks lve spent in a while.
Just what I was looking for.Fit in my 3/8 and 1/2 inch drill just fine.
