69Pcs Abrasive Wheel Buffing Polishing Wheel Wire Brushes Set for Rotary Tool Accessories,Shank 3mm Mini Brush Polishing Kit,for Power-Operated Grinders

It comes with a note that says not to use it at too high a speed and you should take note of that... note. If you spin these up too fast, they'll come apart much more quickly than at lower speeds. That being said, I go pretty much what I expected out of these. I use the most coarse ones the most and will likely be buying a separate bag of those, but the others don't need as much time after removing all the rust (which is what I was using mine for) with the lower grit. I couldn't imagine using anything else to go over all the contours of my tools. These worked perfectly. Just remember not to use at too high an RPM.The addition of the wire brushes and the sanding bits were a nice bonus, but I was really using them for the sanding balls.

Worked really well, cleaned metal perfectly but gently, convenient size so you could get it o cracks and crinkle. Good value for money

Not the most durable, but the bulk amount along with a commiserate price makes this a worthwhile purchase.

These are built well and all of the bits will last a while so in my case I shouldn't need to buy these kinds of bits for at least 5 or 6 more years as I use my rotary tool maybe only...7ish times a year.Having tried all the bit styles but not every individual bit yet, I can at least state that the wire and flapdisks are unbalanced, BUT given their design, it's understandable that they wouldn't be perfectly balanced. I mean, YOU go and try to glue together 20 or so half inch squares of sandpaper to a 3mm rod and have it be balanced. Even with specialty balancing equipment it would be hard to find a place to even securely add a balancing weight and once in motion, the lapping action of each square changes the center of mass anyway so really, they did the best they could and if you press down hard enough to reduce the rpm even farther down than your lowest rotary tool setting would allow, it works quite well(Wire and Flap disk that is) The spongy stuff works naturally on the first 2 clicks on my 20+ year old Craftymans(Old school brand name disguised) AC powered rotary tool but will wobble if you use a speed that's too high. If you can get this for 12$ or so it's a great deal. I wouldn't spend more than $20 on it but that's only because access to wholesale pricing isn't as difficult as it used to be. Also, I would say this is priced PERFECTLY because honestly, these things are consumable tools and if you're handy and help people less fortunate than you in terms of accomplishing simple tasks like cleaning a pot or pan with these, you will go through maybe a hundred or even more wire brushes in a lifetime.

Very practical

I used all of these attachments on a closet I was removing the paint from. The wire brushes were the only problem. When using them on the hinges and handles the wire comes off instantly and stabs and sticks in everything. I find them stuck in my clothes even after washing them.

Product as described. Came fast, good price.

So far, in the limited use I've had with this package, I'm greatly impressed. They are for smaller intracut use and not for big major polishing and wire brushing. Once you know and realize that, you're home free with a great little package for lots of fun cleanup and preservation of your hobbies etc.
