Have this disc bought because I had to move again over a sunken base of a spiral staircase an area of about 50x50cm with upright lamella parquet (bamboo). This required depending on how far the parquet slats then the whole plate to be cut in the base area or on the carriage bolts of the pedestal rose accordingly below in the slats or small sections cut. That was really super hereby. The wheel has now indeed signs of use, but of real wear can not speak. And above all, the 10 euro have paid for this project only - that went unexpectedly smoothly and easily, I had expected there to have frickeln NEN half a day and now I was in ner hour mark through.
I know of no tool other than a Dremel with which one may do a Futzel work properly (there have tasted 190 E with nem Bosch PMF, which is a convenient device but too coarse / large for this application). The disc is now with my cheap Dremel in the luggage and arrive safely at the next tinkering again for use.
