Default MO How To: Remove a cracked set screw

There is a cracked set screw in one of m Kwik 200 tool holders. Itís a 1/2
inch holder so its one of the most common and cheapest to find used. That
being said there aren't as many used Kwik 200 tool holders to be found on
the most obvious source (Ebay) as their used to be. I hate to pitch a tool
holder I already have over such a cheap part.

Here is the problem. There is a tool in the holder and its well secured. I
want to take the tool out, but even a clean crisp brand new hex key just
pops around like the screw is rounded, but its not. I'd like to save the
tool in the holder other wise I might be tempted to press it out.


Well I drilled it out and smacked an extractor into it and still nothing.
Unfortunately it drilled slightly off center and I don't think I want to
chase down to the threads with bigger drills now. I think my next step will
be to see if I can rotary cut a notch or two with a tiny burr and use a
small drift to back drive it out.

Simply drill it out. They are only surface hardened. Good if
you have a carbide bit, by all means use it..but they come out easy

I have to do it a lot in the machine shops I service.
