Rock drill specialist, Doofor was present at the recent Bauma China in Shanghai with its own booth in the outside area. Doofor displayed two of its small size female hexagonal shank models, namely the DF430X and the DF530X. Mining and construction rock drills were represented by two Doofor rock drills, the DF550S and the DF550L. Both have 17 kW of percussion power and are designed to drill up to 70 mm diameter drill holes. The DF550-series is often used in general excavation drill rigs and excavator drill attachments and mining jumbos.

The DF430X is a 5kW rock drill for up to 36 mm diameter drill holes in hard granite with hexagonal rods. This rock drill has been quite popular in dimension stone block cutting. The DF430X has quite a high frequency and thus adding to the straightness of the drill hole.
