Re: taking out broken drill bits, was "Drill Bits and MiniMate"

Rod Miller

This works on brass models. I don't know what will happen
with your diecast boiler. You might want to experiment first.
Perhaps others have more information on diecast.

I remove all ferrous parts and then immerse the brass
part with the embedded broken screw/drill in a solution of
salt water, highly concentrated. Takes a few days, and will
damage paint.

There is a faster method using IIRC alum. Hopefully someone
will chime in with info on it.

I'm sure you've read my last posts asking about the Dremel
Work Station and MiniMite held in the hand (drilling
"freehand"). The reason for this interest: I have a
locomotive shell that I was working on, using a #80 in a pin
vice to drill out holes for hand grabs and, as luck would have
it, or maybe cause I didn't have a steady hand :-(, said bit
broke into the piece, with very little sticking out. Either I
develop a steadier hand or get a drill press. But, back to
the loco shell. Does anyone have any tips or tricks on how to
extract that broken bit? When I say there isn't much sticking
out, I can run my finger over it and there is hardly any
catch, some yes, but not much.
