Hey Folks.
I need to bore a 2 1/2" hole through the brick exterior of my home. I've done some prelimimnary searching for a masonry-quality hole saw that I can attach to my electric drill, but I can't seem to find any such saw.
There are all sorts of hole saws for drilling through wood and some for ceramic tile, but none quite as big as 2 1/2", and nothing that advertises the ability to bore through brick.
Can anyone recommend a vendor or brand, or some other tool that could do this? Or do I need to rent something big & powerful enough?
Thanks for your help.

Try your local rental yard. You will need a drill with plenty of torque for this. Good luck.

Wirepuller's right - this is going to take substantially heavier duty equipment than you think and renting is the way to go.

Ebay has some cheap-o tungsten carbide hole saws (one is 2 5/8") but some bricks are pretty hard. Other problem with hole saws is that they will only cut about 2" deep. If you need to go deeper, you'd need to come at it from the other side or bust out the cut portion so that you could continue drilling deeper. These hole saws are so cheap that I can't imagine they would work well.
When I make holes in cement or brick walls, I'll use a small 3/16" SDS masonry bit in my 1 1/8" Bosch rotary hammer, then make a series of holes around the outside edge of the hole, making them as close together as possible to form a "dotted line". Then bust it out with a 2 lb hammer. Its crude, but it works. Then the hole is cleaned out with a chipper chisel on the rotary hammer.

this is what you need (http://www.nortonclipper.com/Media/Images/S0000000000000001040/Core%20Bits%20-%20Dry.jpg)
You will also need a drill to run it.
They are not cheap so you might want to look to the rental places. The bit alone is several hundred dollars.
This type of bit will work as also (http://www.coastaltool.com/bosch/images/spline-core-bits.jpg)but it requires a big impact drill motor to run it as well.
Rental stores would be your best bet or Xsleepers method works fine but hte edge is not as nice. If you need/want a nice edge, the dry core bit it the best followed by the hammer core and then Xsleepers method.
