No way. Magnetic attraction falls off rapidly with distance. 1/distance^2 in fact. I don't believe that tool will have 12 lbs of force at that distance. If it did, it would be a legitimate health hazard when they snap together.

If they're overmolded with 1mm of x plastic, and they have 12 lbs of force through 1/2" of plywood, then they'll be held together with over 2200 lbs of force when they snap together. 1. You're not getting that tool apart with your hands. 2. That's a trip to the hospital the first time you use it. Completely impossible.

Also they just slide them apart with almost no effort at the 27 second mark. Zero chance there's 12 lbs at 1/2".
