Come to think on it, do they even MAKE a variable speed power saw?
Or table saw? I have used "double-speed" soldering irons and
multi-speed Dremels, but there aren't many tools with selectable
speeds.

Some variable speed tools:

Sabre saws, jig saws, reciprocating saws, routers, random orbital
sanders, palm sanders, drill presses, belt sanders, bench grinders,
angle grinders, lathes, polisher/buffers, engravers and band saws.

Oh. Thank you.

On reflection, there is a universe of variable-speed tools: Hammers,
screwdrivers, wrenches of all sorts.
