Abstract
A diamond dresser having a long life and excellent wear resistance includes at least one diamond tip. An end surface of the diamond tip perpendicular to its longitudinal direction is formed by a {211} crystal plane. Two opposite side surfaces of the diamond tip extending along the longitudinal direction are formed by {111} crystal planes. The present crystal orientation of surfaces of the tip allows each tip to be embedded in a tip holder body on a flat plane while maintaining optimum alignment with respect to the most wear-resistant direction.
