Knotted wire wheel
These knotted wire brush wheels provide cutting action for cleaning hard to get places.
The purpose of the knotted brush is to make the brush more rugged so that the cutting action can be more agressive.
The tufts will also absorb the vibration which helps eliminate bending and therefore reduce wire fatigue.
We use these for cleaning up hard to get places like door jamb areas, roof gutters etc. They are quick and clean paint and rust off very well.
