YT29A Pneumatic Rock Drill is a heavy-duty, high-efficiency and low-consumption air-leg rock drilling equipment. It is suitable for drilling horizontal and inclined blast holes in medium-hard to hard rock (Protodyakonov coefficient f=8~18), and can also drill upward anchor holes.
According to the roadway cross-section size and working conditions, this equipment can be used with FT160A (or FT160B, 160C) air legs, or matched with rock drill jigs or drill stands for both dry and wet drilling operations.
