Review on 300-Pack Steel Wire Brush Set With Rotary Tool Accessories - Rocaris Wire Wheels, Pen Brushes Kit For Improved Cleaning And Polishing by Matt Tito

These are horrible and don’t last. The wire actually comes off and then gets embedded everywhere. Over time the shanks start to bend and if you don’t turn off the dremel right away and catch it, it will destroy the machine. You have to basically feel when it’s getting warped and about to bend and then pre-maturally stop your work and swap the bit.
