Evaluation of Lunar Drilling Technology for Terrestrial Applications. Diamond Drill Bit Evaluation.

Abstract

This report presents the results of a study evaluating four diamond drill bits of the design developed for lunar exploration. Two of the bits were constructed with the original diamond drill bits for NASA, using gem quality, geometrically oriented diamonds. The other two bits were cast specifically for this study, using standard WA-1 industrial diamonds, randomly oriented. Identical rock materials, representing the three major rock classifications, were drilled with each of the bits until the bits were worn out or destroyed.
