The Y19A handheld rock drill adaptable for both hand-held and air leg operation is mainly used for rock excavation in small stone quarries, mining operations of small mines such as coal mines and limestone mines, rock drilling and blasting construction for mountain roads, as well as farmland water conservancy construction projects. This equipment is also suitable for secondary blasting in large mines and rock drilling work in other engineering construction sectors.
Matched with the FT100 type air leg, the dual-purpose Y19A rock drill can perform dry and wet rock drilling on medium-hard or hard rock.
This model can be used together with small air compressors having an air displacement of 1.5-2.5 cubic meters per minute, and its performance is superior to similar products.
