Showed up on time, look as advertised. Do NOT run these on high speed, but LOW speed. They will span out and fray, and shoot crap into your eyes and face on high speed dremel. Live and learn, use on LOW speed or they will HURT you and those around you, as well mess up what you are working on. Remember, they are garbage but work, and high speed will spin them out and become micro fiber metal darts to your eyes, face, hands, people, things, etc.

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 wire brushes are very durable, long lasting, yet soft enough not to cause undue abrasion. They are clearly superior to the number one competitor. I’ll gladly be a repeat buyer.

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

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

I go through bags of these as I use the soft (but slightly stiff) nylon bristles to gently scrub dirt from rock and fossil specimens. Using a rotary tool makes quick work of the task and gets into tiny spaces better than I could do with a toothbrush, etc. I only wish they were sold in slightly higher quantities (say, 25 per bag) as I go through them quite quickly. I think the useful life of the brush is reasonable, though I wish they would last about 10 to 15% longer (wear life is impacted by the abrasiveness of the material, with certain limestone and sandstone wearing them down more quickly than some of the harder materials). Vendor delivery time has always been good and I dont believe Ive ever received any that were damaged or defective.

Absolutely WORTHLESS. I purchased these to help clean stained bathroom tile grout with my Dremel. The one I was using started to disintegrate after about 1 minute of use, even though I was only applying very light pressure. Bristles flew everywhere and were difficult to clean up. Save your money and your time! Dont buy these! I ended up scrubbing the grout with a hand held nylon bristle brush. I would zero stars if that was an option.

these are decent quality brushes. they wear out after a bit, which is why I bought this 10 pack, but any fine wire brush will wear out if you really put it to work.

The are great flat wire brushed that fit my Dremel perfectly. They are cheaper on Amazon than anywhere else. Im very pleased.
