I suppose that it can be anything you want it to be Bob. But, in my case, the triangular tip on this sander gets in many small places. That other detail sander that is shown would be nice to have but I think it might be very expensive. I've got an old Phillips cordless toothbrush that I have thinking about making into a small detail sander. There is a video on youtube on how to do about it. Not very powerful but it might be just right for sanding very delicate things.
