Crystallume DCC rotating tools were first developed in an
NIST (National Institute of Science and Technology) program that involved a research partnership with Boeing Aircraft and three other large manufacturing companies. Some of the information gained in that program is presented below.

Crystallume has continued to be a leader in developing diamond coated tools for aircraft applications.
This aircraft style countersink is designed to be used in a micro-stop cage for producing 100° countersinks with a root radius or angle for aircraft rivets.
