Drilling Bit

It is stated that Diamond saw blades requires high embedding strength of the diamond, while diamond drill bits do not. It is necessary to improve the embedding strength of diamond in diamond saw blades, rather than in the diamond drilling bits. It is recommended to count the number of diamond particles on the matrix surface and get the embedding strength of diamond by calculation. Another recommendation is to use the compound powder of cobalt and tungsten carbide for pelletizing in order to improve the embedding strength of diamond and lower the cost of matrix. There are people studying how to raise embedding strength of diamond, for both diamond saw blades and diamond drilling bit. However, the requirements for embedding strength of diamond saw blades and diamond drilling bit are different. The following parts include the analysis for this problem.

Diamond Saw Blades

In this paper, it is assumed that diamond’s cross-section is hexagonal, which is similar to the actual condition. At first the diamond cutting depth of diamond drill bits and diamond saw blades has been calculated and analyzed. A variety of diamond size and diamond exposure difference has also been calculated and analyzed. It is shown that the cutting depth of single diamond was generally below 0.02mm and the difference on diamond exposure between coarse and fine diamond must be less than diamond cutting depth to achieve efficient rock breaking. Some diamond size design methods are acquired via the calculations and analysis.
