Hi
I have a starrett double end edge finder, I use the parallel end on the mill with no problem but how or for what is the pointed end used for?

I use the pointy end for picking up a centre pop. Lower the point gently into the pop mark and let the weight of the spindle hold it in place. Then adjust the X and the Y feeds until there is no displacement on the main shank of the centre finder.. It's remarkable how can feel a very small displacement with your finger nail. You could use it to palce a small hole under the centre of the spindle in a similar manner.

Hi Brian
It seems quite easy to feel displacements of even 1 thou with the pointed end. I located the point on mine in a centre drill mark, and by rotating the ER32 collet could feel the runout change position with the spindle, so its fairly accurate.
