A Comparative Study Of Some Rock Drill Bits, Charles Roger Knopp
Masters Theses
"The detachable single-use rick-drill bit has attracted considerable attention in the mining industry of the United States during the past few years. While this type of bit has been used for some time in other countries, it has been only recently that these bits have been manufactured in the United States. It was decided to test this type of bit and make a comparative study of a single-use bit and a widely used detachable rock-drill bit"--Introduction, page 1.

"This paper describes a comparative study which was made of the wear and efficiency of different types of rock-drill bits when used under various drilling conditions...The four types of experiments which were carried out had the following purposes: 1. Determine the influence of the size of the bit. 2. Determine the influence of the design of the bit. 3. Determine the influence of the type of hammer. 4. Compare the performances of steel and tungsten carbide bits in limestone and in granite"--Introduction, page 1.
