The rotary drilling pick features a split-body composite structure. The core cutter head is made of high-grade low-cobalt hard alloy material, offering high hardness, wear resistance, and corrosion resistance, and effectively resisting the high-intensity friction wear of rock and sand; the pick body is made of 42CrMo high-strength alloy steel and, through precise quenching and tempering heat treatment, the hardness of the pick body is controlled within the standard range, perfectly balancing hardness and toughness. This not only ensures cutting penetration but also greatly improves impact resistance and fatigue resistance, fundamentally reducing problems such as breakage, tip failure, and cracking during hard rock construction.
The product adopts an optimized tapered tip structural design, with a scientifically reasonable force angle, enabling rapid entry into various soft and hard ground layers and easily completing soil cutting, sand layer stripping, and rock crushing operations. Compared with ordinary picks, it has lower drilling resistance, higher crushing efficiency, and can be adapted to the continuous high-intensity operations of high-power rotary drilling rigs, greatly increasing drilling speed, effectively shortening pile foundation construction periods, and meeting the high-efficiency construction needs of deep pile drilling and large-diameter drilling and boring.
