I wanna know how you broke *three*.
I mean - after you broke one... didn't a clue rake at least try to hit you
over the head about the rest of them?
Not to jump on the jump-on-Jay bandwagon (he's got enough trouble with his
broken bolts already), but wasn't he the guy who asked what the difference
is between foot pounds and inch pounds a while back?
Good Lord, give him credit for trying to do his own work. So he makes
expensive mistakes, I bet he learns from them. I have managed to break
5 drill bits in rapid succession.
Now, If I remember, there are special tools for removing broken bits or
taps. I suggest he look into a tool catalogue such as McMaster-Carr or
MSC.
I have several tiny hardened end mills from MSC. They are no wider
than a screwdriver blade and cost about $20 each and I have used them
for such tasks to get down into a bolt hole (using the dremel tool) to
make a screwdriver slot. You can also use the tiny diamond burr with
th dremel to make a "dent" atop the broken bolt for the drill bit to
start on when you drill it out.
