A bit of bit advice needed. - Posted by Max M.

Twice in the past month I’ve had to go in and fix a bathtub drain. They were the type with a a drain control lever on the overflow plate. These are often a pain and I like to rplace them with the simpler press on/off drain. The problem is that in order to do this, one needs to remove the overflow plate/lever. Both times the bolts that secure the plate broke off.
I couldn’t get a good vice grip hold on 2 of them and ended up trying to use a bolt extractor, one worked, the other one didn’t because the extractor also snapped off. To remedy this I decided to grind it smooth, with a Dremel, and then tap a new bolt hole.
The next problem was that extractors are made of pretty strong steel and none of my drill bits could get into it. Eventually I managed to use another Dremel bit trough the material, and then followed it with a larger bit and tap.
I had to go through 2 Dremel bits, the type with the round diamond cutting head, to do this, and those are expensive buts at $12@.
Should this happen again, I’d like to jump past the Dremel step and get right to using a drill bit. In fact there are many times when I’d like to have a stronger drill bit available.
So my question is: Where can I get the absolutely strongest, toughest, longest lasting drill bits? I don?t mind paying good money for the best tools, so cost shouldn?t be a major concern.
