Abstract:

The report presents results of the field evaluation of a NASA-developed drill system which requires no cooling or lubricating agents. Performance of the NASA system was evaluated at sites in Arizona and New Mexico consisting of volcanic and igneous intrusives. Although the NASA system performed well in most of the materials encountered at a drill rate of approximately 2 inches per minute, presence of unexpected moisture at several sites retarded efficient progress. Conclusions are presented concerning the nature and scope of laboratory tests suggested and justified by the field test results. Author
