Application
Hydraulic rock drills are essential engineering equipment in fields such as mining,road construction,hydropower, railways, and building construction. They are used directly for quarrying stone by drilling blast holes into rock formations, allowing explosives to be inserted to break apart the rock, thereby facilitating tasks like stone extraction or other rock-related projects.Additionally, rock drills can be repurposed as demolition tools to break apart hard materials such as concrete.
ELITE is a high-end hydraulic rock drill brand in China，our company has four major series and more than twenty specifications. No matter what specifications and models you need, we can provide solutions.
