What Does A $20 Drill Look Like? Well it looks like this. As soon as I took it out of my pocket, I knew it was worth it, and I knew it was the only thing that would do the right thing for what I needed it for, which was drill one of the potentiometer holes on the back of the read Guitar back to insert a mini tumbler to reach the front. I sealed part of the drill with tape because I already had a hole. It got boring quickly and cleanly with no drama, making it an easy task to do what I wanted to figure out without ruining an expensive instrument. Just be careful when removing the protective film from the bit as the blades on the counter hole are sharp enough to cut you.
