I've been searching for a small electric drill  that will go down to .4mm,  I've looked at the Tamiya, some people say change the collect  to a much smaller one from the standard one fitted.
It would have to be very slow of course other wise plastic would melt, at the moment I have a decent Tamiya pin vise along with a cheapo, but drilling a large qty of holes is taking so long. Any ideas please.
