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

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 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 for a great deal!

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

I bought these wire brushes to remove paint from window hardware using my Dremel. They didnt take the paint down to bare metal, and they wore out quickly. I thought I could use them in place of heating and scraping, but the paint was not coming off. At first I thought the brush was working because I could feel the chips flying and hitting my arms and face. But it turned out it wasnt paint chips flying off, it was the wire brushes coming out of the cup. I was using the Dremel at the lowest speed - I guess I was pressing too hard. I went through three of them in a matter of a few minutes. Im giving this a 3 star rating because perhaps this wasnt the right application for this product. When I realized it wasnt working, I used the heat gun and scraper on a couple hardware pieces, and then used the wire brush to clean the metal and take off some tiny leftover pieces of paint. It worked for that, but for what I really wanted it to do - these didnt work.

these brushs work well for my needs.

I was sitting one night watching television and wondering, how can I cover the front half of my body with tiny needles that will be undetectable until hours or days later when I bump into something or take a shower? These cupped wire brushes answered that question! First off, theyre cup brushes that become disc brushes once you spin them up to 1000 RPM. They dont maintain their shape AT ALL. So I thought, Ill just hold them against the work surface before I turn the tool on. Nope. Still flatten out. Great, so Ill just make do by using them as disc wheels. Nope. Within seconds they threw multiple needles. And as we all know, once the first few go, the clamping pressure reduces and the rest are quick to follow. Now, Im as frugal as they come and thought, meh, most of these bad reviews are probably from hobby-types who dont do automotive work with their tools and are too sensitive. Listen to me and understand... THESE ARE WORTHLESS. I bought 10. I used the first one on a piston-decarb job for 20 seconds and thought it was a fluke. Loaded a second one, same thing. 3 days later Im still pulling needles out of everywhere, including the worst spots you can think of. Treat this review as if it was you yourself traveling back in time to warn yourself not to skimp to try and save a few bucks. I literally threw the final 8 in the trash and Im so cheap I once made them turn the house lights on a place where the other half dances with little covering because I dropped a quarter and couldnt find it. I lied to the DJ and said I dropped a contact lens. And that is a TRUE story, not just me trying to be funny for a review, even though at the time I was messing with the staff at said establishment. DO NOT buy these. Feed your money into a roaring fire; at least the heat you feel will serve a purpose.

I use these with my Foredom flex-tool, and a bit of vinegar, to get calcite encrustations off my quartz crystal plates (No, not the plates that you eat on). I can really get the bristles deep inside the quartz cavities, and let these brushes do their work. Very pleased with this purchase!

Works well for light rust removal.

Why brass? These brass bristles are fairy soft and can clean up delicate battery terminals on vintage equipment. Brass is less likely to tear into plastic when you slip. I really like that this came in a bag of ten. You can go through these fast.

I have only used one so far and the performance was satisfactory.
