The facility was adjacent to the Fort Knox Army base, located at the intersection of Bullion Boulevard and Gold Vault Road. The main door was twenty tons of drill and torch-resistant material measuring twenty-one inches thick.

What does drill and torch-resistant material refer to? too thick to drill through and open using welding torch, right?

Thank you.

    No.
    The main door was made of twenty tons of a material that would resist attacks made by anyone who was armed with either a drill or a oxyacetylene cutting torch
    You can buy drills that are over twenty-one inches and, given enough time and gas, you can cut through mild steel 21" thick.

    However, there are materials that are very hard that resist drills and have a very high melting point that resist oxyacetylene cutters.

    They are specially designed to resist drills and torches because of their chemical and/or physical composition and the way they were manufactured.
