I was looking for something to drill a hole with and found these which I haven't seen in a while. I went to use one and noticed that the drill bit in the arbor is bent. It's a little special and has a flat so a screw can be tightened against it. I'm sure I could source a replacement drill bit online but I was wondering whether it's worth it. The saws themselves seem pretty flimsy. I'm not sure it's worth replacing compared to getting more solid saws.
