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.
How many can you cut before its worn out? I only need to cut in 4. Also who is the manufacturer? thanks

I have one of those 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
Thanks I will check the website. I am trying to cut through about a 1.5" of material and I read my manual for the cutter and it says 7/8" max. Oops should have read web site first. It says if you can cut from both sides you can go up to 1.75". I would have to cut the decking out anyway so the can would clear. Customer doesn't want the short cans.

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.

I guess it would also cut through the decking behind the plaster after you cleared the plaster from the hole saw...
Thanks for the heads up on cutting the wood.
Is there a preferred manufacturer? Lenox is the only one I recognize in my searches.
Most of mine are Greenlee, although I have one Remington. Lenox is not to be discounted, though.

I just chip the outline out with a screwdriver, then just bash the center in with my hammer. comes out perfect every time.
That can be just too slow sometimes.:blink:
That's rather primitive, don't ya think? What will you do when the lath takes the plaster with it?
