I have two containers with oak (?) flooring. I have a roll around

type of T-bolts that I can drill an oversized hole in the wood, put
the female anchor in there flush with the floor, secure it in, and
have enough room around it to blow out chips once I take it loose?
I have a router table on a base, table saw, and metal bender I'd
like to anchor down. I think if I use a lag, the hole will wallow
in the wood. I could take some square plate, cut some vent blow
holes, drill it, weld a nut on the underside, rout out a place on
the floor, and mount that with countersinks, but I was wondering if
there was anything available that was pre made that I could just
slam down.

Instead of routing the inset holes on the floor, you could use a
Forstner bit.

I have a set of those , they range in size from 1/4" to 1.5" . Any bigger
than that and I'd have it in a drill press - and I prefer to use even the
small ones that way . Tried a couple of bigger bits freehand once ... *ONCE*
.. They have a very nasty tendency to walk unless you're perfectly square
with the surface being drilled , and even then it can be iffy .
Use a hole saw and chisel the bottom flat by hand . It's much safer that
way , and you end up with a nearly-perfectly-centered pilot hole for
whatever threaded insert you end up using .
