| Abstract: | The paper presents the results of investigation of the effect of strength characteristics (strength, strength uniformity, thermal stability) of diamond grits on wear of impregnated drill bits and expenditure of energy for rock destruction by such tools. The influence of strength characteristics of diamond grits on the drilling tool performance has been verified experimentally. The field tests have demonstrated that the better the strength characteristics of the grits the larger the average meterage drilled per bit and the rate of penetration. |
