Dremel 443-3 carbon steel end brush
Dremel 443 uses a narrow carbon steel working head.
How to choose
Check the narrow head against the recess or seam that needs cleaning. It gives a different footprint from the 428 wheel or 442 cup even within the same wire material.

Questions before buying
When should I compare the 443 instead of the 447 set?
Choose the 443 when the narrow end is the working shape you need. The 447 gives a cup and a wheel, which are more useful where those larger heads can reach.
