You'll notice the hole saw is 29mm. The other good thing about the hole saw is that as you are cutting, it only needs to cut a one circle in the wood instead of having to scrap a hole in the wood like a spade would do.

The downside is getting the leftover plug out of the hole saw can be a pita.
If you have a drillpress, the only reason I can see to use a hole saw is sheetmetal.

Actually I believe all hole saws have a notch(or many notches) along the bit itself that are designed to help in plug removal(from the bit). I know mine did. You simply take a nail or pencil and pop the plug out of the bit.
I made my 1st CP with a spade bit and will NEVER use it again. If you are not using a drill press it is too hard to keep straight. I had no problem with the hole saw though. To each their own I guess... ;D

Seems to be simply a matter of preference which one of the spade bit or hole saw to use. Nobody seems to have gotten a really bad result with either one. I'll be able to afford both once I return this wobbling, worthless, piece of junk adjustable spade bit I got :)

Mine have notches too, but sometimes a plug of wood still gets stuck in there. Especially when I used it on oak. I ended up needing to drill holes in the oak an chip it out bit by bit. Took a long time.
I really like having a drill press. I have vauge memories of life before it, but I try to supress them. ;-)

I have found that Hole saws are easier to make a clean hole on thiner material (like 1/8 lexan).
and Spade bits are faster for thicker material
(like 3/4 wood).
just my opinions.
