Definitions for "Superabrasives"
Diamond and CBN abrasives, so called super because of the extreme hardness, "super" performance, and long life. These premium abrasives contrast with more traditional "conventional" abrasives. The name, however, does not denote superior abrasive that can applied universally. Conventional abrasives are clearly better for some applications.
Category of hard mineral abrasives consisting of diamond and CBN; superabrasives maintain tremendous hardness.
