Pretty good tool set for a Dremel tool. Lots of cutting discs, grinding discs plus a diamond disc and rasps. Drills and then sanding drums galore! It actually looks like it will last me a few years in my various projects and I do crafts. The diamond cutting wheel worked well on a piece of glass that I had cut too large. for a picture frame, and the sanding drum I used was held together at high speed on a piece of oak I cut. One of the downsides of this set was the packaging. I would pay a few bucks more to have bigger packaging to keep them inside. Whatever the case, I'll head to the store to find a multi-compartment case to carry everything. Overall I am very happy with this installation. For $20 looks like I'm hired for a few years. UPDATE: There are two concerns about the quality of this set. 1) The wrench that came with it didn't fit my Dremel within a few seconds. I sanded a few thousandths off the inside of the jaws and now they fit. 2) When any of us expect rotating brushes to last a while. we must have hit our heads. Even famous brands don't last long.
