High-performance hydraulic rock drill

Doofor DF430X rock drill is a high-frequency rock drill for general excavations, quarrying and bolting with hexagonal shank steels with a shank size of 108mm [4 ¼”] * 22mm [7/8”] or 25mm [1”]. The rock drill has a female hexagonal chuck.

Doofor DF430X can use water or air as media for drill hole flushing. It has a flushing tube for enhanced flushing power. The rock drill has a patented, high energy piston shape for good penetration speed in hard rock and good drill tool lifetime.

Light piston models DF410X and DF420X are available.

Hydraulic, pneumatic and mechanical steel retainer lock cylinders are available from the manufacturer. Manufacturer can also provide a universal carriage plate for the rock drill.
