Hole Saw 8-inch Metal Hole Saw Kit Set Bi-Metal Hole Cutter Drill Bit with Sharp Teeth for Drilling Holes in Wood, Plastic, Drywall, PVC Boards

Q: Is this 90mm or 3.5"? Those are not the same measurement.

90mm is equal to 3.5433" so it is a bit bigger than 3.5". If this is too big then order an 89 mm hole saw. 89 mm = 3.5 039". Since almost everything on Amazon is bought from China I doubt that you will be able to find a 3.5"US measurement saw. You will have to go to another vendor, like a local hardware store or chain hardware store to locate an American made hole saw. You will end up paying 3 or 4 times more but if the size is critical then that is your best option.

Q: Can this cut deep enough to cut a hole through a 2x6? I need it to go a minimum depth of 1.5" and I can't find the cutting depth in the description.

Yes, I do believe that will cut that deep.

Q: what hole saw arbor with pins will work with this?

A Milwaukee, DeWalt, or Lenox Hole Saw Arbor may work. As you can see it comes with its own arbor, so additional one(s) are not needed.

Q: Can the depth of the drill bit be adjusted? there is very little room behind the hole I need to make and don't want to hit what's behind.

Once the hole is half way through you can remove the center drill bit entirely.
