this is from another forum.

"The speed at the outer edge of the pad will always be greater than the speeds inside when the pad is spinning. Simply put, the outside edge travels a farther distance in the same amount of time as the inside, which means its moving at a faster speed. Make sense?"

"Makes perfect sense. If you placed a mark on the outter edge of a 8" pad and then one at a 6" point, they would be back at the same spot at the same time. The outter HAD to move faster to get back around at the same time.

Remember a DA is oscialating. A smaller pad on a DA will move faster giving more cut."
