Numa5 Spline Shank Down The Hole DTH Drill Hammer for Well Drilling

Product Description

KINGDRILLING DTH hammer products offers a wide range of DTH hammers. The hammers are available for down hole and blast hole, water well, gas, mining applications and use in nearly all ground conditions. Most DTH hammers are designed for use with the industry's most common rock drill bits shank types such as DHD, QL, Cop, Mission, SD, NUMA Shank.

The DTH drill hammer comprises several key components, including the hammer body, piston, bit sub, and drill bit. The hammer body houses the internal components responsible for generating impact energy, while the piston delivers high-frequency blows to the drill bit. The bit sub connects the hammer to the drill string, allowing for seamless transmission of energy to the drill bit, which performs the actual drilling.
