Re: Cheap 56,000RPM milling upgrade (not a dremel :)

Im on my second Harbor Freight micro grinder. It only uses 2 CFM at
full output. The first one lasted a couple of years doing things no
human should have to bear witness too. I like em just fine. As soon
as I find an adequate piece of 3/8" tubing I'll give it a try. It
sounds like its perfect for light engraving. Theyre 40.00 on line
but 47869-1JMA is the 19.99 price. They have a 20 piece diamond tip
1/8" engraving set for 3.99 right now also (#30165-0JMA).
