I'm sure sharper is better than duller, but the first order issue is the
longer lever arm that a hole saw brings to the party. It's like putting
an extender arm on your wrench, you can put a lot more leverage on that
stubborn bolt. Even a very dull drill bit is only a half inch away from
the pivot. The hole saw is providing drag a good 2" out.
