Review by Goomer on March 21st, 2012
This is definitely one of the better HF values out there. Right in there with the Chicago Electric 4 1/2" angle grinder. Much more power and speed than a "Dremel" type tool, much less torque as well. I have one mounted in a router base I made and use it for the occasional sign. It will get into a much tighter radius than a larger tool. Sucks air like it was going out of style, but works very well. One of those tools I liked so well I bought two more "just in case" one crapped out and all three are running fine. I try to keep them lubed by dribbling some oil into the intake. Using mostly carbide burrs from CTI (http://www.carbtools.com/). And all three are touchy on the air control. Not something to leave plugged in as it will keep the compressor cycling continually. But I really like these little guys.

I've only used this tool once. I bought it for detail cleaning on motorcycle engines. Its the smallest rotary tool I've ever owned. I'm quite impressed, especially for a $25 tool.
Like some other HF air tools, greater care needs to be taken in the design/manufacture of the air valves. I can hear air leaking through the tool even with the air control valve completely off.

Small, inexpensive, fast, smooth, diverted exhaust

Air control valve could be better, tool chuck is basic
