On my screwdriver conversion adventure. I wanted to see how possible this was so I hacked up my cheapest Craftsman screwdriver. Cutting off the metal shaft, no problem easy work for the Dremel. Drilling out the tool hardened steal $%@#$. Regular drill bit didn’t work, titanium drill bit useless. Dremel grinding stone barely worked.
