I bought these to clean the nooks and crannies on the outside of the aluminum engine block and used a drill instead of a dremel so I could control the speed. These things are perfect for the job, and the different shapes and sizes of brushes allow you to choose the best one for a specific application. They obviously don't last forever and I have to replace them as soon as they wear out, but that's one of the reasons I bought this large pack because I knew I had to go through a lot for the work I do.
