I'm posting this for those that may not see it in the old Pioneer PDR-555RW CD recorder thread where we're trying to poke through corroded through-holes on a two sided board around a leaking super cap. I feel like someone has already came up with the solution, but I'm posting it for those that may not have thought of it.
This works best as a "free" hack if you already own a dremel style tool. You may be able to do it with a small drill. Take a standard resisitor. Clips both wire leads to about 1/2". I put an angle on the cuts. Insert the body of the resistor into you drill's chuck and tighten. I use it on the slowest dremel speed setting. You may have to tweak the tip slightly if it isn't perfectly centered. It works incredibly fast. Don't press too hard or you'll bend the lead. If it does bend, flip the resistor around in the chuck and use the other lead.

0.6 mm drill bit works well enough.
Clean the hole with a sewing needle, heating the area with soldering iron, and use a pin vice later...
Power tools are too fast, can break bits.

The drill bit is the ideal solution. I don't own one nor do I want to buy one. For this job that I wanted to finish today I'd be waiting days for it to ship to me. Lol. If I didn't have an old dremel tool lying around I would have use my smallest Milwaukee drill/driver. It's speed is governed by hard you pull the trigger. You can make it barely spin with a light press of the trigger. The key is to find a tool with a chuck that is small enough to hold the resistor body, which is about 1/8". After trying to use a very sharp tip of a pick to go at the holes from either side, I was shocked at how fast the resistor lead/bit zipped through the holes. Lol. And the holes were so clean, there's nothing to do now but put those same sacrificial resistor leads I clipped off earlier in the holes, solder them on both sides of the board and clip off the excess length. The best part of this type of micro bit is that you aren't up a creek if you snap or bend them. Lol.
Love this idea, especially since I have a dremel at home. Thanks for sharing, hopefully I'll remember this when the time comes.
