When I'm drilling with a holesaw, I lower the bit until it barely
indents
the wood. Then I raise it up to see how it's lined up. Depending on that
information you readjust or don't. I can't for the life of me see where
the
few seconds required to do this type of alignment justifies the
frivolous
cost of a laser pointer.


Good point, but will it still work with a large diameter hole saw mounted?
