First, I use good quality, tight-fitting tool. In this particular case, I use regular Snap-On sockets but I think there are more modern designs that are better.
Smack the inserted tool with a hammer, many times.
I use heat from a heat gun and candle wax or crayon, as many times as necessary. When I have needed to protect something adjacent, I've fabbed up some heat guards to keep the heat only where I want it. For something like an allen head bolt, you could also use a micro torch in the center of the recess.
I have no idea about those wheels but sometimes the holes go all the way through and your penetrate of choice can be applied to the back side.
