Review on 🔧 Walter 13C015 Mounted Crimped Diameter by Darrell Beecher

I bought these to remove surface rust from a brake caliper before painting and it did a great job. My only complaint is that he started shedding his bristles almost immediately—little sharp wires that are pretty easy to prick yourself with. I used it on an air grinder. I have no way of measuring if I've exceeded the RPM limit it's listed for, but I did do a little extra cleaning as it tends to fall off. However, it survived the first use to ride again, so it's all a welcome addition to my toolbox.
