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?


If you got a welder, drill out the hole bigger till the hole is big
enough to cover the place where you want it. Put a copper rod where you
want the hole and weld up the rest.

Then grind it smooth.
