abrading

A bar of steel having sharp teeth on its surface, and used for abrading or smoothing hard surfaces.

Their energy is dissipated in moving shore drift hither and thither and in abrading the bench when they drag bottom upon it.

But as long as there are any stage roads in sight, or signs of abrading wheels, you will find no trout.

When a part was fully developed, the rubbers were cut to smaller and smaller dimensions and the abrading reduced to minute areas.

The levelling and abrading action of water on rock has an entirely different character.
