FPPO Stainless Steel Wire Wheel Brush & Crimped Cup Brush Kit for Drill,Fine Wire Diameter 0.0059 Inch,for Rotary Tool with 1/4-Inch Shank,Removal of Rust,deburring,paint (7pcs)

Used on the bottom of aluminum boat to remove epoxy coating. The variety of brushes was perfect for hard removable in hard to reach spots to a finer wheel to polish with. Held up and didn’t loose much wire. Job finished and still usable.

The thing I like most is that they are a soft brush. They clean aluminum well without excessive scratching. After one days use, they appear to not be shedding bristles like some do. The rpm limit is 4500, so dont use them with a die grinder. This is a drill speed tool.
