Question: So this redundancy is a good idea for 240v tools, but is not
as important for ones powered at 120v (which are even more likely to be
powered by conventional outlets wired in a series)?

You really don't need to install a disconnect for a dedicated circuit to
each machine in your home shop.

And a separate circuit for every stationary tool unless you're a
production shop w/ an employee at every workstation continuously through
a shift is _WAY_ over the top overkill...

For a home, casual-use workshop as I gather this is, one or perhaps two
30A 240V circuits will be enough w/ outlets judiciously placed for the
major equipment you now have and some consideration given to what you
think you may want to add in the foreseeable future. You, as an
individual can never be using more than one at a time so, other than the
one tool, the only other loads active simultaneously will be the
potential DC and maybe a compressor.

Circuits for electric heat, etc., should, of course, be separate.

The "non fused disconnect" at each tool is, in ordinary terms, the plug
on the end of the power cord.
