The picks for rotary drilling rigs are mainly applicable to various hard soil layers, sand gravel formations, hard frozen soil, soft rock, medium hard rock, hard rock, weakly weathered, moderately weathered rock and other formations with high strength. During the construction of rotary drilling rigs, the performance of cutting tools (rotary drilling tools, rotary drilling picks and tooth seats) is required to be high, so the rotary drilling picks and tooth seats must have good impact resistance, wear resistance and other properties.
