High-performance hydraulic rock drill
Doofor DF560L-2M is a high-frequency hydraulic rock drill specially designed for underground production drilling and tunneling. The DF560L-2M version is equipped with two OMS-series rotation motors. It has a very low overhead, only 84 mm from the drill center line, which is of great benefit in using the rock drill underground and in limited space applications. 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.
Optimal maximum hole diameter for the DF560L-2M is 89 mm [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.
