2.8P Russian Bayonet DTH Rock Drill Hammer - 98mm OD, 110-140mm Bit Range for Mining and Quarrying

3" - 33" DTH Hammers designed for mining, quarrying, exploration, water-well, geothermal, construction and geotechnical drilling projects. Every KINGDRDILLING DTH hammer is manufactured in our own factories with advanced production facilities. All components are precision-manufactured using high-quality raw materials and undergo proprietary heat-treatment processes to guarantee exceptional durability and quality.

Down-the-hole drilling (DTH) involves a drilling hammer at the bottom of a drill string. It relies on three elements for drilling holes: bit loading (weight), rotation and air. These active elements combine to be highly efficient at crushing rock.

Pneumatic down-the-hole (DTH) hammer is a pneumatic drilling tool using compressed air as a power source. It is suitable for drilling in pebble, gravel, and hard rock strata. Commonly used in building pile foundation construction, bridge projects, mining operations, geological exploration, hydrological wells, and other industrial applications.

The primary difference between top hammer and down-the-hole drilling methods is where the hammer is attached. The hammer in DTH drilling makes contact with the bit during operation, while top hammer drilling activity is concentrated at the very top of the drill string.
