Wear you PPE!!!

3” cup brush?
You are kidding, right?
Never in a million years. Cup brush rated for my angle grinder, even then i dont like them. Wires fly and stick into everything.
Yes they do.
Years back I had an inch in my crotch that kept bugging me. It would go away then come back. Turns out, a wire was stuck in my underwear and would poke my balls then not poke my balls. I work construction so I found a corner and pulled my pants down and looked and looked...Finally I found the wire strand and yanked it out.
Relief!
