| Abstract:This paper reviews the use, structure and capability of the core drill. The problems with the drive and transmission systems of the core drill are examined through field tests in the view of the requirements of the drilling process. The versions of core drills are introduced. It is suggested that the version of core drill be considered in shallow, medium deep and deep catalogues. |
