There is a cracked set screw in one of m Kwik 200 tool holders. It’s 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.

Try drilling out the set screw. Often one can drill a hole lengthwise
through a screw/bolt which seems to release some of the tension and
allows the resulting "tube" to be removed easily with an "easyout".

Even fairly hard set screws can be drilled with a high speed drill bit
at low cutting speeds and high feed pressure.
