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

I used them on cleaning up the magnesium valve covers and they work fine. I used dremel first, but that overheats quickly, so, I use them with the RotoZip. They work, do not fray excessively (I only run them at 10000 rpm), maybe not as good as Dremel brand, definitely not as precise, but for the price, I think they give better value.

At the time I purchased these brushes they cost $7.99 for a ten pack, thus, they obviously only cost about 79 cents each. Given their low price I would rate them 4 stars. You can only expect to achieve about 5-10 minutes of run time from them during mild to moderate buffing, and considerably less when exerting heavier pressure. From my experience, the brass is soft enough to brush most metals without scratching, and they seem to be ideal for removing rust from small tools, etc. They certainly are not the equivalent of high-quality brass brushes costing considerably more, but then again, they are only 79 cents. I strongly suggest wearing eye protection when using these (as you should with any power tool) because the little bristles WILL fly out and hit you. Thats the only reason I knocked off one star. Other than that, from a cost to performance comparison, theyre worth purchasing.

Not quite as durable or well made as the Dremel brand ones, but for the price they are a steal.

They dont last very long, maybe 10 minutes of use each before the wires are down to nothing. Wish I could compare to real Dremel products but theyre too expensive.

I needed a tiny wire wheel and these were the exact fit and performed the job perfectly

Great for detail cleaning with Dremel tool. Just wear safety glasses and long sleeve shirts.....these puppies shed their bristles at high speed, and dont last very long! Also at Dremel speeds they will NOT maintain the cup shape but immediately splay out like a wire wheel.

Poorly made, don’t hold form, and brass slivers fly all over the place.

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

The price is fantastic. A Dremel brush is more expensive, but it may be worth it because these dont last at all. Wear goggles! The wire bristles do fly out in rotation or when they break.

TEMO brushes for Dremmel tools are not the best quality. They do good job of removing rust or whatever from your project, but the bristles are not attached to their base very well, and if you have your Dremmel rotating at high speed, or under load, the bristles will start flying off (NOTE: You MUST wear safety glasses when using these. I was getting hit in face constantly by flying bristles). At the end of the day, the Dremmel branded bristle brushes are clearly better quality and last longer, but the TEMO are sooooo cheap for a bag of 10. At the end of the day, I would say if you are in your garage or outside, and wear safety glasses, the TEMO are an OK option. If you are inside working, I would not use TEMO because of the bristles that you will find on your workbench, the floor, embedded in your clothes, etc.
