On re-reading, it appears you are correct and I am wrong. I'd pull the
plywood!
You'd pull 1 1/2 inches of glued and screwed plywood? Destroying both
the plywood and the joists?????..

It took me just over an hour to manufacture the tool and do the job.
With no damage to the structure.


Your Original Post:

[I need to drill through 6 2X8 joists which are accessible only from
the one side. They are spaced 2 feet on centers. (need to pull cable
across to the center of the floor). The joists are sitting directly on
concrete, and the decking is 1 1/2" (you read that right) plywood.]

See anything about plywood Glued to Joists there? See anything about $50/yd
Carpet there?
No, but just the 1 1/2 inch plywood alone makes it an expensive
proposition, even without carpet.

Two strips from a piece of 3/4" ply = 1.5" thick ply, about $20 here.
Your billdrit cost you more than that.
