I have recently gone to CBN wheels with shrouds removed on my 8" grinder. Thing is, the metal filings produced fly everywhere and are just another mess to clean up. At the Phoenix National symposium, I seem to remember seeing a grinder fitted with shrouds over the CBN wheels but have been unable to find any info on it. I'm thinking that shrouds incorporating magnets would go a long way to contain the filings. Anyone have any knowledge of a grinder with CBN wheel shrouds?
