Why? It could well be argued that it would be safer if you *didn't*

happend to touch the bench as the same time as the faulty drill you
won't get a shock.

A faulty drill placed on an earthed metal workbench will blow a fuse
somewhere.

A faulty metal drill placed on an isolated metal bench will make the
bench live. Touch that and you couldl be acting as an earth conductor!

So which is more likely to happen? I was just saying that earthing
the bench isn't *necessarily* a good idea. You need to assess the
environment and then decide. If the floors are vinyl covered for
example then not earthing it is safer, on the other hand if the floor
is damp concrete then maybe earthing it is safer.
