Scope of application
Model 7655 is a highly efficient rock drill. It is mainly used in either rock drilling
work such as mining and tunneling, or in railway, water conservancy construction
projects and stone work. It is suitable for wet drilling on hard and medium hard
rock, or for drilling horizontal or inclined blast holes. 7655 can be equipped with
pusher leg FT160A and FY200A lubricator.
Model 7655D is a low energy consumption rock drill based on model 7655. It has
good performance at low air pressure, with long air lines or powered by small sized
air compressor. 7655D is mainly used in the same applications as the 7655. It can be
equipped with pusher leg FT160A and FY200A lubricator.
