TEMO 10 pc Carbon Steel 3/4 Inch Flat Wire Brush #428 1/8 Inch Shank for Dremel and Other Rotary Tools

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

I use these for cleaning the piston bore on aluminum brake calipers from a motorcycle. Its soft enough to not damage the aluminum but still able to clean away any deposits. Its mounted in a Dremel, 1/8 inch collet, and used on low speed which is more than enough for cleaning. Instead of a brake cleaning fluid that evaporates quickly, a penetrating oil or WD-40 is used then the caliper is rinsed with brake cleaner. One brush was used for 6 calipers and still almost like new. It works great for the piston seal groove and dust seal groove thats narrow and hard to clean otherwise. Will buy again when needed.

These do not last but a few seconds if you use it for grout BUT when youre using it with the cleaner (and goggles with pants and long sleeve shirt) it lasts longer. You have to be gentle with it and it works fine but its nothing compared to what Dremel brush does.

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.

What i liked about it. Worked great with my Dremel. Started wood burning project and the brushes are great for getting into the small areas and cleaning them out.

These are cheap and you get what you pay for. Compared to the same in a Dremel brand, at a much higher price, they have a very short life. Single use at most/best. The bristles roll over very quickly and become useless.

Tore them all up in under 30 mins doing what I would consider light duty cleaning dirt off small tile pieces.

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

Not very tough. Wear out quick.

Was good value, although theres not much life in each, thats for sure. They will quickly warp and bend and be practically ineffective.
