The rock drill has good performance under low pressure,it is suitbale for act impetus with long Air pipe and small air compressor.And it is use for drilling in mines,quarries,railway construction,water conservancy and national defence project facility. When it is matched with Model FY200A oil reservoir and Model FT160A or FT160B air-leg, it can perform wet drilling under various of rocks at aclinic and incline orientation,it can also use in the trolley without Air-leg.
