.0025" = 0.0635mm
.0005" = 0.0127mm

Yes I DID mean 0.15, but on our side of the big pond the use for
commas and points is just the reverse of the USA, so one thousand
in the USA is 1,000.00 and in Europe we write it down as 1.000,00
Sorry for the confusion...

What does strike me as surprising is that Davids' specs are less
than half of the ones I found. I guess the difference in performance
would be a good explanation?

Hope this helps,
