Review on Polishing Attachment Grinding Polisher Stainless by Paul Dobson

Impeller will not fit my Dewalt 4" Grinder or my cheap 4" Ported Freight Grinder. The shaft on both of my grinders is 5/8"-11 and the threaded hole on the drive wheel is m10x1.25. A little frustrated that I wasn't able to use it when I first got it, but plan on using it with drilling to try and tap the impeller to make it work. If that doesn't help I'm working on a new impeller. Don't buy this and don't expect to be able to use it without modifications. The only reason for two stars rather than one seems to be the best the frame seems to be pretty solid but I haven't been able to use it yet so maybe that could change.
