Cross Slag Removal & Anti-jamming Efficiency: Optimized cross-shaped slag discharge channel, combined with streamlined groove design, the discharge speed of rock powder and gravel is increased by 30%, effectively reducing the probability of drill jamming and hole blocking, and the operation stability is greatly improved in fractured zones and wet drilling conditions.
Impact Resistance & Wear Durability: The matrix is made of 42CrMo alloy steel, treated with quenching and tempering plus carburizing and quenching. The cutting edges are made of tungsten carbide-based cemented carbide, with optional TiCN composite coating on the surface, which has excellent impact toughness and wear resistance, and is not easy to chip or wear during high-frequency impact operations.
