Product Description

The YT23(7655) rock drill is a kind of high efficiency air leg rock drill machinery. it is mainly used for blasting holes and other drilling works in a quarries, railway construction, water conservancy construction and defence project facility. When it is matched with the Model FY200A  Oil reservior and Model FT160A or FT160B Air-leg, it can perform wet drilling and blast holes from different and angles.

The YT23D(7655D) 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.
