As I was trying to machine MT2 taper yesterday, it occurred to me that if the angle is off by just a small fraction of a degree, the two tapered parts would in theory touch at only one place (i.e. a ring).

This got me thinking that even with two very accurately machined tapered parts, the actual surface area of contact must be relatively small relative to the total surface area of the taper. Is this correct?
