DeWalt N437890 Chuck Nose Piece Ball Spring For DCF887 DCF809 DCF892
Genuine DeWalt Spare Part.
This ball spring is located in the chuck / nose piece of the DeWalt impact drivers. Due to its location and nature this part is the most common part to fail and need to be replaced. This is what essentially keeps hold of your screw driver bits whilst working. When this snaps, you need to just pop it out and replace it with a new one.
