We have used a 1-inch diameter hole saw to
take cores from rotted window sills. That worked fine.

Subject: [BP] Plug Cutter?
I used a plug-cutter bit
on my drill, hoping to take a nice clean piece out of a log that would keep the
finish layers intact. It didn't work. The first several rotations
destroyed the finishes. Nice hole, but not what I was after. Yes, I
can and have taken samples with pocket knife. I'm sure a scalpel would
work marvelously. But, I was so hoping for something neat, tidy and
uniform.
So, is it the wrong tool? Wrong speed? Or lack of skill with the tool?
