Dremel 535-02 brass wheel brush
535-02 is a two-piece pack of 3/4-inch brass wheels.

How to choose
Choose the wider brass brush when it fits the area being cleaned. A smaller brass cup or end brush is worth comparing for a recessed surface.
Compatibility and limits
3/4-inch brass wheels · two mounted brushes
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
What if I need brass bristles in a narrower opening?
Compare the half-inch 536-02 or the narrow 537 end brush. The 535 wheel needs more room around the working face than either smaller shape.
