they're very useful for cutting/grinding anything, but there are a lot of different tools/tips available for die grinders - cutting, grinding, brushing, rotary fileing, sanding, polishing ... higher speed wire brushes are avaiable, but you MUST wear protection

I'll never be be without one as long as I've got a compressor that'll handle it
