my house has walls that are very thick and heavy. Cutting electrical
outlet holes and ceiling holes is very difficult. Using a saws all
with a big tooth demolition blade, I get maybe 20 inches before the
blade is flat. Ceramic blades are much worse. Am I doing it. Right?
I find finer tooth blades are worse.

What is the material that you're cutting? Other than outlet boxes, what are
you cutting on the ceiling?
