Hi all,
I'm often running into the situation where, trying to remove to replace knobs on HP (and any number of brands) units, I need to use very small hex or other types of bits which get ruined very easily, sometimes on first use. These bits are from sources such as Amazon, where very good assortments and sets are easily available. The steel they use may not be of top notch quality.
Before you ruin any more bits or setscrews, get some Kroil. Best penetrating oil I've ever used, and I learned about it here or on the similar Tek group. I've used it to free things that I had given up as hopeless. Apply a bit as close to the threads as you can get, wait an hour or so and hit it again, and try moving it a few minutes later.
