Hi
I need to drill 1.5 - 2.0mm diameter holes to a depth of about 8mm in very
soft alloys / lead.
Using a small model maker's drill of unknown rpm only seems to get to
about 2mm easily. The workpiece warms up (actually, quite hot) and it
seems that drilling stops.
Is there a technique for drilling this type of material? High rpm or slow?

You should find that quick spiral drills work better than ordinary jobber
drills.
