One thing I have found is to use a bit that is as short as possible, and insert it fully into the chuck ... that looks like a 12 bit, and those things will wander all over, especially in #30 and #40...
Yep, I tried the short bits too.

You can get a usable set from Harbor Freight; fine for drilling aluminum.
These rods are steel .. but I don't mind tearing a couple bits up if I can get them drilled properly.
