I've got a cabinet in the laundry room (see pics) where I want to cut
off about 1/4" from bottom (bottom face). I will stop perhaps 2 "
from each end of cabinet. The board / trim is about 11/16" thick and
has 1/2" clear on back side from bottom before I reach the inside trim
piece (picture 3 of 4).

I was told to consider using a dremel but do they sell an attachment
that would allow me to cut a straight edge 1/4" from bottom? I don't
want jaggered cuts and I don't know right now if the bottom is
perfectly level.

And is there a better tool for this? I already have a dremel tho.
What type of dremel blade and accessory is good for this cut? I don't
know if this is some kind of composite board or wood since it's
painted. Feels like wood but I can't be 100% sure.
