I have a B&D electric drill and the carbon brushes are sparking

Inspecting the brushes there is about 1/4 the original length left
and
the nds are rough, so they need replacement.

However, will replacing the brushes/cleaning the commutator cure the
sparking?

If not, what else could be causing the sparking?

in 9/10 cases yes
