Chenghui supplies DTH hammers for water well drilling, mining, quarrying and hard rock drilling applications. Our down-the-hole hammers are available in different sizes and shank systems to match various hole diameters, compressor capacities and drilling conditions.
Different configurations can be selected according to operating air pressure, rock hardness, drilling depth and rig requirements, with matching DTH drill bits and accessories available for complete drilling systems.
DTH hammers use compressed air to drive a piston and deliver repeated impact energy directly behind the drill bit. This drilling method is widely used for water wells, mining, quarrying and construction because it can provide efficient rock breakage and stable borehole straightness in hard formations.
