How do top hammer drilling tools perform under high-frequency operation and sudden geological changes?

Top hammer drilling tools are manufactured from high-toughness alloy steel and feature reinforced, high-strength thread designs. This enables them to withstand frequent impact loads while maintaining stable and efficient energy transmission. As a result, they adapt well to alternating rock conditions and sudden geological changes. These tools are widely used in urban ground support systems, tunnel excavation, and continuous underground drilling operations, delivering both high drilling efficiency and long service life.

Can top hammer drilling tools maintain hole accuracy and prevent deviation in fractured or inclined strata?

Yes. The tool system is designed with high-rigidity connections and reinforced centering cones, ensuring stable alignment during drilling. By selecting appropriate button types and bit face designs for the geological conditions, hole deviation can be effectively controlled within 1°. This significantly reduces hole wandering and prevents bit jumping in fractured or inclined formations.
