I bought this sanding tool because I had seen it on a carving forum being used on a die grinder. It looked like a big leap forward in rapid sanding. However I have yet to use it. It comes with no English instructions. Apparently you put it on an angle grinder which would make it rather clumsy to use. We don’t have the right size collets here in the UK for mounting this on a die grinder. I think I’ve bought a white elephant and Manpa tools should supply collets and if possible die grinders for their products.
