Used in a small dill press to remove rust from screw heads, safety glasses and dust mask. They held up fairly well before the bristles wore off. Good find.

Not nearly as durable at the Dremel product. I would say that you would use 5 of these for every 1 of the Dremel brand. Packaging was neat, they look good, just not durable.

Works at lower speeds, but if you go too high pieces start flying out, so wear your goggles. The y will spread apart an stay that way too.

I bought these cause they were quite a bit cheaper than the Dremel brand. But they dont hold up near as well.

They worked good for me cleaning the inside of my outdrive on my boat. Even at the recommended speed I went threw them quickly

I bought these for jewelry making. The brass brush wheels in class produced a fairly high finish. Other reviews have said that these are stiffer. That might explain why the finish is more matte. The thing I found more troubling was the oil that would spread out to the end of the bristles as I used the wheels. I can only assume that there is residual oil in the hub from production. But it left my work oily and dirty. I will spend the money and get the Dremel version next time.

these are NOT the ones that pull a Mission Imposable and self destruct in five seconds after turning it on. I restore engines and i work these little babies hard with my dremel to reach those negative corners before painting. Trust me, these hold up.

Keep RPM low and use a light touch. Let the wheel do the work.

Like many mentioned it sounded to good to be true, but in this case it was true. These brushes are a very close replacement to the Dremel 405 but at a fraction of the cost. When these wear out I will certainly buy more of these again! I love them.
