I have purchased 7 Dewalt grinders in the last year and am generally happy with them. However, this particular grinder I bought is absolutely dangerous with a 6 inch cutting wheel. Mandrel is out of balance and has excessive vibration. Impeller wheel, it will shed chunks from excessive vibration. I use high quality wheels, mostly premium Metabo wheels, not a plain black Metabo wheel. Now I'm not sure what to do with this coffee grinder because it's used by me have already used a drawing pen to write my name on it so I doubt I can return it.
