IIT Jumbo 51Pc Drum Sanding Kit - Fits Dremel - Includes Rubber Drum Mandrels - 1/2, 3/8 & 1/4

Not sure about durability yet I put them with some other drums so I am not sure which ones I have been using.

Sorry for being a little over dramatic but the 3/4 diameter mandrel is not designed for high speed dremels. Or not the ones that I received. The two that I received bent 90 degrees in my dremel tool without ever applying them on to my project. It was a good thing that they didnt snap off or slip off and hit me in the face or gouge a piece of plastic off my project and sent it flying. It was also a good thing that I had a firm grip on the dremel because the dremel could have fell out of my hands. I have used the smaller 1/4 & 3/8 mandrels without any issue. Im afraid to use the 1/2 ones. FYI: The Dremel brand aluminum oxide sanding drums last longer than this brand. Its worth spending a little more to get longer lasting sanding drums. The seller claims Outstanding value & quality - turn your Dremel or other rotary tool into versatile high-speed sander. This is not true for the set I received. EDIT (Nov 2, 2012) The seller contacted me and offered a refund or replacement. I opted for the replacement of the 3/4 diameter mandrels. I wont use these larger mandrels on a high speed dremel, but I will say they work fine on a drill press (lower speeds) and I guess on a dremel where you can adjust the speed. The seller has my respect for doing the right thing and replacing the damaged items.

This is a great large cheap pack of dremel sanding drums and attachments. Anyone that has used these drums know that they wear out quickly, but at this price you arent super concerned about that.

Works well, not as durable maybe as the name brand ones, but they work.

Great value for the money get a lot of pieces and they hold up fairly well

This set has worked as advertised and the multiple sizes are very useful.

I experienced no issues with this item.

Much better price than name brand drums but tend to fit loosely on the mandrels. Good cutting ability but they wear quickly on hard surfaces. Overall a good value for occasional use.

I bought these to use with my cordless Dremel to file my dogs nails. So far they work great! No issues at all.

The sanding paper fits loosely in the drum, but when it is spinning, it doesnt come off. It works, but I have to be careful not to loose the sanding paper.
