Can we demo?

For those familiar with the catch phrase from Bob the Builder, the answer is "Yes we can!." We think. But maybe without the exclamation mark. It's possible, of course, but harder than it looks. We finished off the bricks around the fireplace and took one L-shaped cabinet out (see pictures below). My drill doesn't have the torque to unscrew the cabinets, but my father-in-law suggested buying a drill bit that bores a large hole (like those used to make holes for door knobs, only smaller). It worked. We drilled around the screws. And the beauty is that the cabinet still hangs (precariously) on the plug of wood rather than crashing down when the last screw is removed. This makes the process seem safer.
