Concrete coring drill: Hilti DD 350-CA, starting at $5,519

The tools of the break-and-enter specialist are often also those of the construction worker. A diamond-tipped coring drill can bore smooth holes through the thick concrete of a building foundation, elevator shaft—or bank vault. A version of Hilti’s DD 350-CA was used by the group of elderly men who carried out the $20 million 2015 Hatton Garden jewelry heist in London.
