I purchased a US$1.05 screwdriver. Pull out the steel rod. Use a metal file to grind down one end so it fits Surge's bit holder. The width is a perfect fit. I only need to make it a little thinner.
These bits are much smaller than the standard bits. It comes with 6 bits: 3 flat and 3 Philips. They are all smaller than LM's double-ended replaceable bit.
Total costs: $1.05 and 20 minutes.
The picture is miserable. I did not bother to take good pictures today.
