Thanks, Tai Fu. That's too bad. I guess the slower grinder has much more modest air requirements. Maybe I'll get that instead.

I see that they did change the air requirement . The souix uses less air. I will change the listing thanks
As for run out , these have very little as compared dremel tools. The die grinder uses a roller bearing and not a bushing.

I thought the 70k one in the link was the Sioux. It's the one that presumably needs 5.5cfm.

Charlton

I did correct that. I think there was a typo on the site.
I apologized for that.
there was a 5.4 at 90 psi rating it is adjustable. You can turn the speed up and down.

John, What about oil mist?

if you check out the video I use a paper towel that is folded over the end of the exhaust hose and taped to it . You only need a drop of oil . if you over oil that can be an issue. The higher speed and the bearings make it a cleaner cut. These are used at CF Martin and Custom pearl Inlay among others.

I found that with proper oiling I can hear a difference in the sound. When oil gets where it needs to go the RPM increases quite a bit...
