### ⭐⭐⭐⭐ They seem to work well, and last quite a while.
*by J***E on October 25, 2023*

I've been building a welding cart, and since I'm just getting back into TIG welding after 30+ years, I have a lot of welds to grind off. I've used the slop out of the disk and it's still going strong, so I'm pleased with the longevity. After the welding cart I'm going to start welding on a stripper pole I'm making for my rotund great aunt. I need to make it out of super thick steel pipe because she keeps bending the store-bought ones when she does that flying jump mount from across the room. At 315 pounds, that women can tilt the planet when she hits, so I have to lay in a lot of welds. These flap discs will be great for that. Wish me luck, and the poor pole too.
