Slower = Softer. At slower wheel speeds, there is a higher force per abrasive particle causing the grain and/or bond to break down quicker. Faster = Harder. At higher wheel speeds, there is lower force per abrasive particle making both the grain and bond seem more durable and resistant to breaking down as designed.
