DHD3.5 DTH Hammer

The 3.5 inch DTH (down-the-hole) hammer is a compact yet high-performance drilling tool, engineered to deliver efficient impact force for boreholes ranging from 90mm to 130mm —making it a top choice for diverse industrial needs.

Its core applications span critical sectors:

• *Mining & Quarrying: Ideal for hard rock drilling (granite, limestone) and ore extraction, with high impact frequency cutting through abrasive formations while minimizing bit wear . It pairs seamlessly with DHD3.5/Cop35/QLX35/Terranox3 bits for blast hole drilling in quarries .

• *Water & Geothermal Well Drilling: Excels in medium-depth well projects thanks to optimized air consumption and stable penetration, even in mixed rock conditions .

• *Civil Construction: Used for foundation piling, road/bridge anchoring, and tunnel drilling, compatible with crawler rigs for on-site mobility .
