Hey it's cheap but I need something to poke a hole in the shelf to make a grommet for my electronic cables for tablets, phones, laptops to introduce e-readers. That I glue every night lest empty strings fail. I then used a different size to drill some holes in the back of the console that supports my HDTV and holds my cable box, DVD player etc behind the glass doors. The cable box has overheated and shut down. 4 holes in the upper back solved the problem of ventilation. I then used another to drill a starter hole in the wall to route the wire to the new outlet. It was cheaper than just buying an expensive drill press. And still useful. Yes, it's cheap steel and has limited tooth life, but it's done a lot more for me than it cost and I expect the set to do a lot more good.
