The gearing attached to the lead screw will determine how easy it will be to
cut metric threads. Most quick change gearboxes are setup to make both
English and metric threads.
You are best off purchasing a machine that is designed
for metric threading then - it should have a metric
leadscrew and a quick change gearbox tagged in metric
That way the threading dial on the carriage will function.

When cutting metric threads with an imperial leadscrew, you cannot disengage
the half nuts, but must wind the lathe backwards to get the tool back to
point. Once in a while, it is not too bad, but for a lot of cutting of
metric, you REALLY want a metric leadscrew.
