Math question
 
I need to get a ball bur to make a rivet set to fit these dome rivets. Head diameter is .324" and height is .067". Metric equivalents are 8.2mm and 1.7mm.

How do find the correct bur head diameter to make this shallow bowl?

If I understand correctly, you need the equivalent spherical diameter.

thanks! What is the math as I may have to do this for other rivets?

A google search for a circle from three points. I just put two points on the X axis and the other on the Y
