We use Carbide hole saws on a slow speed drill. But they are expensive. I believe that a 6" is about $125.
I have an adjustable bit that has a plaster bit.
I have one of those cuyyers but it burnt the bit up and barely scratched it. Can you show me a pic of which bit you use? thanks
I bought the unit many years ago-- 25yrs or so-- they had wood bits and a plaster bit.. The plaster bit is much thicker-- I haven't seen a picture but I will look. Better still here is the website
How many can you cut before its worn out? I only need to cut in 4. Also who is the manufacturer? thanks
Not sure it's still going after a few dozen holes. I believe that it's a Lenox Carbide Hole saw.

Home Depot has a 6 3/8 milwaukee carbide hole saw for arouns $30.00 does not come with an arbor.
I just finished installing 7 ceilng fans and metal fan brace box in a metal lath and plaster ceilng. I used a 4 1/2" carbide hole saw it thru the metal lath without any problems as long as you use low spee . I would cut out all the plaster holes first and then go back with a Bi metal hole saw to cut thru the planking
Carbide hole saws do not like cutting thru wood.

Several hole-saw makers offer carbide-grit saws that are the right size for remodel cans.
Is there a preferred manufacturer? Lenox is the only one I recognize in my searches.
I just chip the outline out with a screwdriver, then just bash the center in with my hammer. comes out perfect every time.
