Helping a friend finish out a bathroom, new construction roughed in long ago
and then left alone. There is a rough toilet drain stub sticking up out of
the concrete floor, still capped with the test plug. This is a 3" ABS pipe
that was wrapped with sill sealer (foam sheet) before the slab was poured,
so there is about 1/2" clearance for the o.d. of a flange to be installed
around the pipe. A ceramic tile floor is set up to the edge of the foam.
I have been told that there is a tool called an internal pipe cutter that
will cut off the ABS clean at the right depth below the tile to install a
standard toilet flange. No luck finding such a tool at the local hardware
or my familiar industrial suppliers MSC, McMaster, Grainger... nobody knows
what I am talking about.
If someone can describe the tool for this and/or how this is ordinarily
done, I'll be eternally grateful. thanks
