Rocaris 10 Pack Flap Wheel, 120 Grit for Rotary Tools，1/8 inch Shank (32X10X3)

Using my rotary tool, I gave it a test on some scrap wood (see photo) and it bit right in. I was able to cut a groove in seconds. So, it seems to me to be a bit more aggressive than 120 grit. I took off a star for this apparent inconsistency. Otherwise, these are a great addition to my rotary set. Better yet, Im throwing a few in my drill bag because I see them being helpful when I do something like deck building. There always seems to be a time you need to take off a little of a bad cut or find a way to get around a proud obstruction. These should do well for that purpose. I did not try it on metal. I see no reason that it wouldnt also take off rust as advertised because these have some serious bite to them.

Flap wheels are a staple in any rotary tool/flex shaft accessory kit; they offer an easy way to carve, smooth, and blend curved areas of a surface. The Rocaris 10-pack, at about $1 per wheel, is about one-half to one-third the price of my favorite name-brand flap wheels. As you might expect, theyre not quite as well put together as the more expensive versions: The glue joints can be a little uneven, the trim on the flaps can be kind of haphazard...but given the abuse these wheels get, its probably a minor issue. From what Ive seen in my first wheel, theyre not going to last as long as some, but again, at the price thats a minor issue. Less minor: They are positioned as 120-grit AlOx wheels, but as others have noted they seem more aggressive than that. The initial cutting is more like an 80-grit at least. However, after a couple hours use, they soften up to about where I expected them to be, out of the box. (Hint: If youre buying inexpensive abrasives, its ALWAYS a good idea to test them on a piece of scrap (metal, wood, glass, stone), and compare them to what youre used to.)

Currently working on refinishing some metal baseboard radiators that were looking tired and rusty. I used these in my Dremel to get at areas a palm sander couldnt get to as well as to focus in on particularly rusty spots as well as decades old paint blobs. Definitely sped up the process and reduced the pre-sanding time as I prepared the parts for new paint. Exactly what I was expecting.

I havent used many flap wheels but I know they can be pretty aggressive and these definitely are. Keep that in mind when using them. I know not to expect delicacy when using a flap wheel so I only have used them for major removal of wood or Ive also used them to remove rust from metal in order to get down to a better finish. I took the advice thats in the listing and soaked the flap wheel for a couple minutes before using it, then blotted off the extra water and let it spin for a bit before using. Of course stuff is flying everywhere so make sure to where eye protection and grubby work clothes when using these. Try to stay out of the line of spin too in order to avoid the worst of the stuff flying everywhere. That being said, I found this flap wheel to work about like I expected. It takes a good deal of material away rather quickly. As far as durability they seemed to last about as long as I would expect when it comes to a sanding product. Its possible that more expensive name brand wheels would hold up longer but these didnt just quickly give out either. I think it works out in my favor when it comes to duration vs. price. Im happy to keep using these whenever I need a flap wheel for my dremel projects. I dont think theres too much more to say. Best luck. ~Cheers!

The flapwheels are not marked and the grit is more like 60 and not 120. It damaged my work surface.

These were just the right size to use on my water pump. I wanted to clean inside the ports. I am used to flap wheels will a larger shank (1/4) but these smaller 1/8 shank worked fine. Will need to get some with a coarser grit for other projects. Would buy these again. Thumbs up.

Will quickly remove rust and polish and deburr metal. They also work chucked into a drill, though slower. These are very abrasive, function more like coarse grit than 120. Would not use for fine sanding of wood, they will leave scratches. I cleaned, polished, and sharpened a rusty pair of long handled pruning shears. The flap sander worked great and only took a few minutes for the whole cleanup. Follow the instructions and soak the disc first, otherwise they are too stiff. Be sure to wear safety glasses, the dust and sparks fly everywhere sometimes right at you.
