What would be an ideal Ampage for this application?

Someone compared your application to a Dremmel and those are
130-175W, so at 6V would be 20-30A

Most mains motors make more heat than anything else.

It seems cordless go for a higher voltage to imply quality or power.
The world has gone mad. What is wrong with 'shaft power'?

A genuine Dremel has quite a lot of "oomph", metallurgists use them to
grind and then polish a few square centimetres of steel often starting
from a pretty rough and rusty surface. For cutting through a couple of
millimetres of wood with a proper saw you probably only need 10 watts or
so.
No. You will need more than that.

50W min. Id prefer 250...
