Throughout the grinding wheel's history, the bond that holds the abrasive grains together has proven as important as the grains themselves. The success of grinding wheels began in the early 1840s, when bonds containing rubber or clay were introduced, and by the 1870s a bond with a vitrified or glass-like structure was patented.

The grinding surface of these "runner" stones, or top stones, is concave and carved in spoke patterns. The runner stone sits atop another "bed stone" or "nether stone," which is also carved. As the top stone rotates, the grain first gets cracked in the middle of the two stones, then is pushed to the outside by the spoke-like pattern.
