i bought a $16 impact drill. Problem is that there are sparks(though small) where i think the carbon brushes are : Answered

 is that normal?



As Re-design rightly says the sparks are perfectly normal & will become smaller & less noticeable as the brushes bed into the commutator.

As long as the sprites stay inside the drill you are safe from them.


Actually quite hard to prevent it.

+1. And they should get smaller as the drill is used and the brushes seat.
