I've often wondered myself why a variable speed would be necessary other
than sanding. Like you, I also have a few sanders which do the job. Anyone
care to offer insight to why variable speed cutting would be necessary
elsewhere?
Doesn't the variable speed model have a more secure way of holding the
blades? Is the motor the same power?

It could just be that it is a copy of the Feon. If Fein did it. so would HF.
