20 pcs Steel Cleaning End Brushes Pen 1/5″(5mm) x 1/8″(3mm) Wire Brush Rust Paint Removal Bits Polishing Rotary Tools

Great for cleaning hard reach spots. I used it to clean grease and tar from my wheels, cleaning electric contacts. Use on tail light circuit boards, wheels,bcm, and electric door locks. No issues after cleaned and prep

These work pretty good. None of them last very long, but these seem to last longer than name brand versions. Some reviews complain about the wires flying off. All of these type of rotary tool wire type brushes will do it. Keep the rpm's down and it will substantially reduce it from happening. Very satisfied on the purchase. They are much more economical than buying from a box store.

Great Product as described, No Issues

I'm restoring a 40 year old air cooled engine and there are parts of the engine that are not easily cleaned. Shy of using a sand blaster I tried these small wire brushes and, while it takes some time, they definitely do the job. Only a 4 star as it took a day over a week to ship it. Yep, kinda spoiled when shipping is free, this one wasn't, but it gets here quickly.

A cheap disposable product that is fine for what it is.

I'm doing paint and rust removal on an old atv. At first I tried a variety of round, cup, and these I'll call burrs. Learned quickly that speed and control were important. Regardless you are going to be pelted with strands of wire flying at the speed of ouch. Don't wear a sweatshirt, trust me. It feels like a cactus hug. The round and cup had a short life, but the burrs could last much longer and actually performed better with use. So I stocked up on these. Suggestion to Dremel users. I have a 4000 with variable speed. I start the speed at ~12. After some wear it will develop a point. Then I can increase to 25, avoid punching the tip directly, always at an angle. Good luck in your project

Thanks for the suggestions to keep from spreading. Be careful that the shank diameter is actually more like 2.95/6 mm. My collet requires 3mm so will need some mods.

This is a game-changer for cleaning paint off metal when doing plug welds. It’s so much easier than using a spot blaster. I’ve done over 100 plug welds, and I only used two of these so far. I bought one locally, and it cost more than this pack of 20 did. And it lasted half as long. Get these!
