Dunno mate.

Indeed. The two part numbers I listed cover 3-12mm and 10-25mm
respectively. So, you drill a small pilot hole and use the small one,
changing to the large one if you need to go over 12mm.
Useful aspects of reamers like these are (a) you can very gradually
enlarge a hole until you get it just the right size - no need to ferret
around for the right sized bit (b) they do a very good job of rounding
out mishaped holes, and (c) because they're hand operated (don't worry -
they're not hard work), there is very little risk in breaking the
workpiece.
On the downside, being tapered, they do create a slightly tapered hole
but it's rarely a problem.
I would recommend that anyone who regularly has to make mounting holes
in plastic or aluminium sheet has a pair of these.
