Review on 🔧 ABN 38-Piece Set – Auto Wire Brush with Handle, Extension Bar, 1/4in Hex Drill Shank – Stainless Steel, Brass, Nylon by Keith Barra

I am an automotive technician and purchased these wire brushes specifically for derusting brake caliper bores and various other vehicle components which bores can rust. The FIRST time I used it I already had 1 broken wrist and I have not abused it in any way. I attempted to de-rust the knuckle so the ball joint could be put back in place and it just broke in half with minimal pressure. I really hope the rest of the bits aren't that flimsy because I just received this set last Friday and it broke on Wednesday on first use. Can it be guaranteed?
