Electric sparks generated by my new cordless drill

This is normal for most all universal motors. A corded drill will do the
same providing you have an opening to see the brushes.

It being a NEW drill, the brushes may spark less as the brushes "wear in"

yes, and no
excessive sparks indicate worn or improperly seated brushes...

might be a good idea to take it back.
anyone else?

Traves

All DC motors spark as the brushes make and break contact. Yes, this is
normal. BTW, it doesn't have a "reverse gear". The motor reverses.
