Abstract
The degree of wear and criteria of repairability of drill bits with diamond—hard-alloy cutters were studied. Statistical data on service life of different types of diamond drill bits were analysed.
 
 
Keywords: headway, mechanical speed, superhard materials, diamond layer, diamond—hard-alloy cutter (DHAC), wear resistance, drill well, polycrystalline diamond cutter (PCDC)
