- Abstract
This paper presents the results of the authors' field investigations into the performance and operation of tungsten carbide tipped rock drilling bits during the past two years. The paper is divided into three parts:
Part I - briefly outlines the historical development of this type of bit, and serves as an introduction to the subject.
Part II - contains the detailed results of the investigations into the various factors which affect the performance and effective life of the bits. Rock drillability is defined and discussed, and a Drillability Index is developed.
Part III - covers the general operation and maintenance of the bits and drill steels.
