Review on Coarse Clean-N-Strip Disc: 3M SandBlaster 9681 4-1/2-inch by Chris Horton

Too bad I didn't read the description well. Shame on 3M for developing a proprietary BS connection that requires a different adapter for my grinder. So. Am I going to buy a quick adapter to use the burnout pad and then completely remove the adapter to attach the shock wheel from the box store? Waste of money but I'm ashamed I didn't read more carefully. There are at least 30 million grinders in the US. Pretty sure 29.9 million people don't use BS 3M's catchy marketing name for quick install. Save money on this product and buy a regular Scottish grinding wheel.
