The same thing happens to a lesser degree when you use stones that have different thicknesses. And, naturally, they all *are* different. The drill stop collar lets you compensate for the different thickness of the stones in the blink of an eye. There are several videos on YouTube showing how to set it up. I think this item is a must buy for anyone with an Edge Pro, especially when you are using the finer stones. It takes you from being close to right to perfect every time.
