SE 228-Piece Rotary Tool Accessories Kit with 1/8" Shank - Comprehensive Set for Polishing, Drilling, Engraving - Includes Sanding Bands, Grinding Stones, Woolen Wheels, and Wooden Case - RA9228

I have had this set for about 4 years and use it all the time. Its a fantastic value. I havent worn out any of the bits and have only broken several cutting disks which are brittle and fragile. Its always been my fault, not the tool. I use the set with the Black and Decker rotary tool which has also been a champ all this while. My advice on both is to first draw what you want to do so that you plan out your cuts, then go slow and be patient with any of the tools and you will be fine. The diamond grinder, ive used it to death on steel and it refuses to wear out. I also bought several titanium and diamond bit sets from this MFR but have yet to use them because this set just goes and goes. Id be lost without it. You can polish, grind, sand, cut steel, stone, ceramic, concrete, anything i suppose. Im currently using the set to drill, cut and polish sea shells for something im making for my girlfriend. Ive used the set to cut and shape wood, like the wooden eating utensils im prototyping. All of the tools work if you are easy on them and patient. I use water spray to cool the tools during cutting or grinding. Nothing in that box is worthless, and there is too much stuff, too. My only complaint, if any, is that it would be helpful if the bit shanks were a little longer because the rotary tool isnt that small and needs to be further away from the work so that I have space but its no big deal. Best $15 I ever spent. Should I need the set again, I just hope they are still around. Oh, one thing if its not been mentioned elsewhere, the number 228 doesnt mean 228 different bits, the number refers to the abundant spares, like cutting disks and sanding wheels, polishing pads. Also counted are the different sizes of bits unto which you would place the cutters, etc, and a tool is also included to mount those cutters. If this is you first set of such tools, get it and check it out well before buying supplementary bits because you just might find everything you need is already there.

Have not used yet but presentation and the case are really cool. Nice assortment. Nice quantities.

I got this fairly recently so haven't had time to test out every single accessory on something though I eventually intend to do so.At less than half the cost of a similar set of official Dremel accessories, this one isn't too bad depending on which accessories you're most interested in. The first thing that I noticed is that one of the grinding "stone" accessories in the box was improperly glued to it's shaft sideways in such a way that it would wobble like crazy if actually used. But there are a few other aluminum oxide grinding stones of different shapes and this one wasn't a particularly important shape to me, so this didn't bother me that much.The second thing I noticed is that the edges of the box aren't exactly well rounded off and seem likely to give someone splinters. Fortunately though this product comes with the stuff needed to fix this, and I wanted to test out the sanding drum and mandrel anyway. So I went about rounding off the edges and noticed no problems with the included drum mandrel.For the price, these are the sorts of quality issues you can expect, but if 99% of the accessories in the box are good then it's still a good deal.I also used the polishing wheel mandrel with felt wheels, and I think I tested out the machine screw mandrel with a grinding wheel as well. I can't tell the difference between any of these mandrels and the Dremel ones.About the only thing I notice is that the grinding wheels included in the set are every so slightly more coarse-grained than the ones that came with my tool. So though I haven't tested all of them, I'm a little more concerned about the quality of the grinding wheels and other grinding accessories for some applications where a certain fineness is needed like say removing rust from stainless steel so that you can polish it up afterwards. The Dremel wheels I have seem like they'd be a little better for this.The wire and nylon brush attachments also seem of decent quality. I used them for a while with no signs of them flying apart or anything.So despite some quality issues of the sort you might expect (especially with minor stuff like the wood box edges not being rounded off well enough to prevent splinters) this still looks to be a worthwhile set for the price. If it were any more expensive I'd give it 3 stars, and if it were double the price I'd give it 2, but for $15.50 or so enough of the accessories in the set are good enough that the mediocre quality of some of the parts is made up for in overall value.

I heard rattling while the outer shipping box was still sealed -- but when I opened the wooden box, every piece was in its place. A couple of grinding wheels -- 12 of them in one compartment -- were slightly chipped. There appear to be more pieces than are listed on the box; I tried to match everything to it, but was left with at least 5 extra pieces. I also was surprised by the 10 fiberglass cutting wheels (as well as standard wheels) and the three rubber polishing wheels. As a newbie, I didn't realize that rubber or felt polishing tips need a screw-tip mandrel. Without the box, I'd have been stuck with no way to use six expensive little Dremel pads -- without going to the store and paying too much for the extra mandrel. The SE box's Amazon page doesn't come close to describing its contents. The pieces all feel sturdy and secure. A couple of mandrel-mounted grinding stones have drops of glue on the working faces. The wooden box itself is smooth inside and out. Each mandrel fits into its own plastic tube, across two tiers instead of compartments, and the compartments across the front of the box are stuffed solid. This isn't one of those collections that rely on the numbers of sanding sanding bands and sanding disks to hide the lack of variety among the other pieces. I haven't figured out how to stash my not-so-many other rotary accessories in the box. I will.
