Good luck driving straight through the entire bolt. I'm looking to see if a long 1/2" or 3/4" core bit exists. core the whole thing out, can't find any, maybe a diamond bit with slots cut in.

Are you saying a 24-36" long 1/2" or 3/4" drill bit?

i'm saying a 6" long core bit. Core out the whole lag after popping the head off.

OP said is saying the wood is stripped out around the lag screw, not that the screws cannot be removed…

Ok well they need something to grip maybe drill a 1/4" hole alongside the lag then hammer in a 1/4 dowel so the lag can grip and pull itself out.

That or try to find out where they would come out the backside, use a forstner or something to find the tips and push them out while spinning them.

Drill and tap the head for a 10-24 2" bolt. throw a tack weld on them cut the head off the bolt, close a drill chuck on it and spin it in reverse and pull.

Drilling things out like this is a PITA, you'll never get it right and by the time you are through the hole will be 3/4" from the drill wandering all over.

You are way overthinking. This is a lag screw in wood. The screws can be removed pretty easily. Just put a screwdriver under the head and back it out. Then they just need to drill through and install carriage bolts.

I've drilled holes for carriage bolts in a 2x10, narrow side (as in 9.5" long). Had a 36" bit typically used for installing electrical cables, was easy.
