Hello gents,

Quick question..... Is there any problem using a variable speed
controller on an 110VAC die grinder? The problem I'm having is all mine are
24-30k RPM and I need to run much slower for doing cylinder head porting
with abrasive wheels and discs. I normally use air tools for this but my
compressor makes more noise than air and it's a big drain on the wallet to
run. If this is ok to do can you recommend a suitable unit. A dial or foot
pedal is fine. I just don't want to fry the brushes or unit all together.
Electric stuff is not my forte so I figured I better ask first.

Thanks as usual!

Rob
