Bonded vs. Coated | Types of Abrasives Used in Grinding Wheels

Bonded Abrasives in Grinding Wheels. With a grinding wheel, you will be using bonded abrasives. The grains are bonded together with a binding agent or resin to add support to the grinding surface while cutting. The type of grain, the spacing, and the bond material will determine what materials an abrasive can cut.
