The auger teeth adopt a split-body composite structure. The core cutting tips are made of high-grade low-cobalt hard alloy material, featuring high hardness, wear resistance, and corrosion resistance, which can effectively withstand the high-intensity friction and wear of rock and sand; the tooth body is made of 42CrMo high-strength alloy steel, and through precision tempering and quenching heat treatment, the hardness of the tooth body is controlled within the standard range, perfectly balancing hardness and toughness, which not only ensures cutting and penetrating capability, but also greatly improves impact resistance and fatigue resistance, reducing interrupted teeth, broken tips, and cracking in rock construction from the source.
The product adopts an optimized streamlined tooth tip structural design, with a scientifically reasonable force angle, enabling rapid cutting into various soft and hard ground layers and easily completing soil cutting, sand layer stripping, and rock crushing operations. Compared with ordinary cutting teeth, it has lower drilling resistance and higher crushing efficiency, and can be adapted to the continuous high-intensity operation of large-power rotary drilling rigs, greatly increasing drilling speed, effectively shortening pile foundation construction cycles, and meeting the high-efficiency construction needs of deep pile holes and large-diameter drilling investigations.
