50pcs Abrasive Buffing Polishing Wheel Set for Rotary Tool with 3mm Shaft,Mini scouring pad Brush Polishing kit, Removal of Rust,Deburring on Metal Surface (grit 400 Black 50pcs)

i use these to work on firearms mostly. from removing metal to polish works good.

These are a particularly effective tool for removing small casting imperfections in brass. I’m building America 250 exhibits, these abrasive wheels make polishing brass castings a breeze. Please see photos-these abrasive pads help make polished castings like this possible. See images of flintlock rifle trigger guard . To be fair, I have all the various grits. And 4000 grit emery boards give a mirror finish. See the before & after photos.

I've used these quite a bit in cleaning and rebuilding an old motorcycle engine. They do the job cleaning off old gasket material. The only negative is they don't last long and you would be wise to wear safety glasses and a breathing mask. Lots of dust of course, and the abrasive sheds pieces steadily and they sting when they hit your face and arms. Worth the money, however.

Worked very well for paint prep

Sometimes a wire Dremel type brush just doesn't do it. These things work really well, taking all of the rust and crud off of parts very quickly, leaving a satin brushed finish. Note that there are a number of grades, so pay attention to what color and grade you are buying. Two comments - these are consumables. They work well, but they also break down very quickly, and shed a lot. Wearing eye protection recommended, and don't use over (or on) delicate surfaces.

I ordered these to try to polish scratches out of glass. I also ordered diamond paste in several grits to accompany and tried all the heads with all the pastes. I noticed some polishing with the finer grit on both the attachment and the diamond paste. It took like 20 minutes one piece and I was able to remove some of the surface scratch but not all. I am thinking this is still not the right tool for what I need but definitely a great tool for many other purposes. Easily switches out on the Dremel tool and the heads don't seem to wear down. It's really great to have a selection of many grits in one package.

Returned. Not what I needed.

These work really well for removing leftover paint/primer residue after using paint stripper off wrought iron railings. While most of the surface areas were "final stripped" with a SCT (surface conditioning tool), these took care of almost all other areas that SCT couldn't reach due to size of the tool. These little sanding dudes left very little remaining to be addressed by small metal files and "pickers" and razors... Just plan on using way more than most likely originally thinking... The railing I used them on went thru them pretty quick. I did have a few, maybe about a dozen out of a few hundred, fly apart noticeably quicker and in chunks/rings. This is the only reason it didn't get 5 stars.

They worked well cleaned off the old gasket as I hoped . Thanks Tim

Work well

Son muchísimos, nunca me los voy a terminar en esta vida, tal vez en la otra. Pulen el acero de pequeñas partes muy bien.

these are numerous in the bag, and no wonder why, they probably last 5 minutes doing a light job at best, heavier jobs are pointless using these

Primero compre un paquete con ruedas abrasivas de varios colores, desde luego estas son las más ligeras equivalen mas o menos a una lija el 400, son las que más me gustaron porque no rayan el metal a pesar que se desgastan rápido, por ello decidí comprarlas solamente un nivel de abrasión pero no opacan.
