On screw pullers, I fully agree - that's just not how they work! You draw
the puller to full tension, then give a few sharp raps on the screw with a
heavy, but soft metal (bronze or lead) hammer. If that makes things loose,
then tighten the puller again and repeat until it pops free.
But what's wrong with using a power tool to run a punch through, once it's
properly started - and you're confident that you're not trying to force it
through material that's beyond its limit? I'd agree that it not exactly
desirable, but for speeding through a few operations, particularly in soft
/ thin materials, I don't see how it's going to damage anything.
