Has anyone used a Bucktool grinder?

I'm looking at this dual-speed grinder and wondering if anyone has any experience with it.

Many of the reviews on Amazon are very good but one says that "the diameter of the shaft was not to spec. The CBN wheels I bought to use with this grinder would not fit. The hole in the wheels measured 0.625 (5/8) the shaft measured 0.627 (627/1000)"

It would be a concern if standard wheels wouldn't fit. I was thinking of using it with a wire brush and being able to switch over to a reqular grinding wheel and run regular speed for things like grinding a mower blade

Pulled the trigger.

I was able to find out a little more information and it seemed worth a shot.

Besides, my other primary alternatives seemed to be out of stock
