【 摘 要 】

Directions of a significant increase in effectiveness of rock destruction with tools equipped with super-hard composite material inserts are reviewed and justified. Drilling tool designs with the cutting insert in the form of elliptical Cassinian oval and the asymmetric ring cleaves are suggested. Versions of laboratory stand designs in order to determine the power consumption of rock destruction are developed.
