Drilling 1/4" holes on a 1/8" thick mild steel plate on a floor drill
press but a few of the holes were off. Try to corrected it on my drill
press to widen the holes with the same 1/4" drill bit the bid just
deflected from side pressure. I do not want to use a larger bit since it
will make the holes too large. I then try to corrected it with a Dremel
with one of those small cylindrical grinding stone attached to a 1/8"
shaft to get in the 1/4" hole but the grinding stone only lasted about 10
seconds before disintegrated. So what is the right tool/method just to
widen those holes on one side?

Next time, get an optical center punch!
