The YO20 is designed for drilling blast holes and performing other rock drilling tasks in quarries, small mines, and various construction projects. It is ideal for drilling horizontal, vertical, and inclined blast holes in medium-hard and hard rock. When equipped with the FT-100 air leg, it can drill blast holes in a range of orientations and angles.
NOTES:The air pressure for the YO20 rock drill should be maintained at 0.4-0.5 MPa. When drilling high-hardness rocks, the air pressure can be slightly increased. However, if the pressure exceeds 0.6 MPa, the machine experiences increased vibration, making operation difficult. The machine can still operate stably with air pressure below 0.4 MPa, but the efficiency will be lower.
