■ Introduction
The rotary drilling bit (bullet teeth) is designed for all types of soil, rock, and concrete layers. Its conical teeth provide excellent penetration performance. The body is made of high-strength alloy steel and undergoes heat treatment for superior toughness and wear resistance. The cutting heads are crafted from hard alloy using hot isostatic pressing for enhanced durability. Springs are made from high-strength spring steel, and wear-resistant washers are produced from heat-treated high-strength steel, ensuring long-lasting performance under demanding drilling conditions.
