Don't cut an opening between the garage and basement, that's supposed to be a rated fire wall.
Also, be wary of an exhaust fan in a room with fuel-burning appliances -- it is very easy to get the balance wrong and suck air in via the flues, which of course is air that contains the dangerous products of combustion. Make-up air needs to come from somewhere, so the door should be undercut or have louvers.
If it's the layout I think it is, you've got a concrete or block wall for the basement level, and the laundry room is far enough from the garage entrance that it is largely underground. If you make a ceiling-fan sized hole in the ceiling drywall within about 8 inches of the outside wall, you will find that you can drill a small hole through the rim joist and siding to outside, and then work from that hole to center a hole saw with Arbor. Then you can mount your bath fan and vent to the outside.
I just use metal hole saws, you also need the Mandrel to attach it to your drill. The best way to do it when working with metal is to but the hole out of a piece of wood first, clamp the wood down to your case and then use it as a guide so you get an even cut. It works with acrylic case windows too but you have to be gentle.
don't use that adapter, you need a holesaw arbor betwee your holesaw and the drill chuck. it will look something like this.
that's what the two holes on the holesaw are for.
No, it will not work, sorry. You need this for the 3.5 hole saw:

I'm trying to cut 6" wooden circles out of 3/4 to 1" thick pine boards. I purchased a hole saw and shank to use with my drill press, but am having issues with it.
It takes ~10 minutes to cut one disc because of how slow (vertically) I have to take it. If I use more pressure than the slightest increment down, it jams instantly. I've tried speeds as low as 700 RPM all the way up to 2300 RPM with little difference. Also, even when it hasn't jammed, the cut is very poor. It's ripping a lot of the grain causing me to have to do a lot of sanding to produce a finished edge.
I think maybe the issue is the quick swap shank. The retractable pins don't swivel, which means I can't screw the saw on quite all the way. It has a slight wobble because of this, which I think might be too much for a 6" saw to function properly. I'm thinking of trying this hole saw instead, hoping it fits together more snugly and cuts better.
Before I buy more tools, does anyone have any thoughts on the best way to cut 6" circles 1" thick?
