Chenghui supplies DTH drill bits and carbide button bits for water well drilling, mining, quarrying and hard rock drilling applications. Our DTH bits are available in multiple diameters, face designs, button configurations and shank types to match different hammer systems and rock formations.
Product selection can be matched according to hole diameter, rock hardness, abrasiveness, hammer model and drilling conditions.
DTH drill bits work together with down-the-hole hammers to transfer impact energy directly to the rock at the bottom of the borehole. They are widely used in water well drilling, mining, quarrying and construction because of their stable drilling performance and good hole straightness in hard rock formations.
