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

These little flap discs work great! Ive used them with a rotary tool as well as even a power drill and they really do the job. Theyre 120 grit but theyll take metal down quick at high rpm so you have to keep them moving. They do fray up a bit but they keep working until the grit wears down. Id recommend 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.)
