Indeed, the limited clamping capacity of the 'Micromot'-system can be nuisance. On the other hand, operating a 6 mm cutter on this small machine at 10000 rpm could bring some rather dangerous torque down onto the worktable, even if the motor only has 100 W. Perhaps that is the reason, why they limited the clamping diameter to 3.2 mm (= 1/8").
I was not aware that such aftermarket spindles were available ...
For such small cross-drilling operation some sort of dividing head with tailstock might be useful. Or an ER11 collet block that can be held in the vice. The collet would recenter the material in a repeatable way.
As you now have a mill (and had a lathe already) you could make yourself a miniature machinist's screw-jack to support the outboard end of the parts to be drilled.
I am using an old watchmaker's lathe bed with the dividing head and its tailstock and made this sort of jack I was talking about:
The idea of the jack could be adapted to the Proxxon, but one needs to find a way to attach it to the table - on mine I simply used a couple of neodynium magnets, but the Proxxon table being aluminium this obviously would not work.
