Dremel 442-02 carbon steel wheel brush
1/2-inch carbon steel brush in the 442-02 set.
How to choose
The narrower wheel gives you a different footprint than the three-quarter-inch 428. Check the actual opening before choosing which wheel reaches the surface.
Compatibility and limits
Half-inch mounted carbon steel cups · two in the offer
Care
Use the brush tips with light pressure and check the speed limit printed for the exact brush. Dremel’s cleaning guide explains how pressure affects the working bristles.
Questions before buying
When would a narrow end brush make more sense than a cup?
If the opening has little room around the brush, compare the narrower 443 head. The 442-02 gives a broader contact patch when the cup can reach the surface.
