Such a tool simply does not exist and even the types that make small holes are quite large (floor standing) and they all make a lot of noise. Are you trying to get out of prison or into a bank? If you are in prison it must be a long stretch as you seem to have been asking this question for months.

Not very efficient method---I would use a pneumatic (air-powered) drill and muffle it very well. They use them to cut through 5 inches of steel in about 20 minutes when building aircraft carriers. That or acid or a lot of little laser pointers. Good luck on the bank heist....will forward to FBI.

basically noiseless way could be with an acid---hire a sturdy chemist and then pop the guy once you're finished robbing the economic enterprise....undesirable sucker. Technically, you are able to desire to apply a drill with some extreme-tech noise cancelling speaker equipment and vibration dampers. Lasers too.
