DHD350 Down The Hole Hammer Drill Rig Tool 5inch 125mm OD with 10-25 Bar Working Pressure

The DHD350 Down The Hole Hammer is a 5-inch high air pressure drilling tool designed for demanding mining and construction applications. Engineered with DHD350 shank compatibility, this robust hammer delivers reliable performance in challenging drilling conditions.

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 efficient at crushing rock.

Drilling through stone, brick, granite, and even marble requires tough drill bits made of hard metal. Kingdrilling drill bits are specifically designed to tackle stone and can bore through these hard surfaces with ease.

Cobble is extremely hard and very difficult to cut, making directional drilling challenging. During drilling, cobble pieces move and therefore rock bits cannot penetrate them because of the constant movement; instead of being cut, pieces of cobble roll away and do not stay in place.
