I read a number of low-rated reviews before purchasing. They all commented on how the brass bristles flew off. I had a small low-speed job so I figured they couldn’t be THAT bad. They are. Bristles were flying off immediately. If you do purchases , wear eye protection. Very unsafe. Junk.

I used these to polish a stainless steel pot. This is not the first time Ive done this and it always worked fine. First thing to happen was the cone shape flattened into a disk. Right away. Then the wires started to fly off. I checked the speed of my Dremel tool and it was slow enough so none of this should have happened. I used it for not more than one to two minutes and it was fully worn out. Sent them back the day I received them.

Much cheaper than Dremel original part and are work exactly the same!

the worst Ive ever used. stay far away from these. they are a waste of money, trust me.

They do what they should. Wear glasses when use because the wires do tend to shed under use.

So far so good. Will see how they hold up.

They worked okay but didnt last long and I had to keep changing to a new head. They would ball up so quickly.... but, then, so did the name brand when I bought them, so its just the way it is I suppose.

If you used this at about 2k rpm maybe it would work but my dremel starts at 5k. Bristle pull out easy. Uneven. Just not practical for use. 5 bucks at Walmart gets you only one brush at Walmart but lasts way longer

These worked great w/ the Simichrome polishing compound. It made my job much easier with less effort and even faster than last time! These didnt wear out like some of the natural bristle ones last time I had to polish something that was brass. I could apply more pressure and they didnt flare out and wear prematurely. Very durable material - love them! :D

These brushes do what they are supposed to do as NYLON brushes which is to be used on softer materials. They perform extremely well when used with common sense and do the job they were made to do extremely well. AND: they are a tremendous bargain. Thanks Golden Coulee and Amazon
