Those "teeth" are actually flat cylindrical projections, each with many individual diamonds lined up in the same plane. It's therefore an "interrupted flat" surface rather than a toothed" surface.

The theory is that the gaps between those cylinders channel away swarf and lubricant, which is a very common design approach in diamond abrasives. Because the edges of the cylinders don't "cut" they don't leave marks as a rasp would.

Some other examples of the same basic approach:
