DF560L-EXT

High-performance hydraulic rock drill

Doofor DF560L-EXT is a high-frequency hydraulic rock drill specially designed for underground production drilling and tunneling. The DF560L-EXT has a very low overhead, only 84mm from the drill center line. The rotation motor of the DF560L-EXT can be installed on the right-hand or the left-hand side. The rock drill has a separated flushing box. Flushing media can be water or air. Flushing parts are available in bronze or in stainless steel to avoid corrosion caused by saline water. EXT-version is for back hammering to break drill strings and for removing stuck drill steels from the rock.

Optimal maximum hole diameter for the DF560L-EXT is 89mm [3 ½”].

The rock drill can be equipped with shank adapters (striker bars) R38, T38, and T45. It can be equipped with stainless steel, separated flushing head for underground mining, bolting, and grouting.
