Wire Brush Wheel Cup Brush Set,12 Pack Coarse Crimped 1/4 Inch Shank Wire Wheel for Drill Attachment

The add says metal, brass. The wires are brass colored steel.

The regular brushes are perfectly fine, the long brushes are just too soft. They really don’t do anything useful.

Probably work fine if you’re not actually wanting solid brass.

Used product.

Works ok
