Yes, used with a drill. Just so we are on
the same page, the set up usually includes a 3/16” drill bit (which acts
like a pilot guiding the drilling so the large diameter “saw” does
not “walk” around) with a mandrel that can accept a hole saw which
is a cup-shaped piece with teeth along the cutting edge. I think the 5/8”
plug cutter was not big enough for what you needed PLUS a plug cutter can be unwieldy
with a hand drill. It is usually recommended to use a drill press for plug
cutting. I have also cut plugs by hand but would not want to study the wood or
preserve the finish with this method.

Eric,
1" Hole saw? Would this be like a circle cutter? Used
with a drill? Cores from rotted wood is exactly the kind of result I'm
after. Perhaps my 5/8" plug cutter just wasn't big enough!?

[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?
