FAQ
The pneumatic rock drill is a small rock crusher. It can be used for crushing or drilling concrete, frozen earth, rock, and so on in many industries like mining, road construction, soft rock exploiting, ditching, building construction, foundry, and so on. As a powerful rock driller, it can drill horizontal, inclined, and vertical blast holes can be drilled in hard or medium hard rock using dry type or wet type drilling methods.
Our pneumatic rock drill is forged by quality material with advanced techniques. So the product features high toughness, high anti-wear performance and great shock resistance. The CNC machine tools are adopted for the manufacturing of the pneumatic rock drill. In addition, the Unicaso automatic production line and thermal treatment can further guarantee the outstanding product quality
We have a microcomputer controlled testbed for the quality test of each product. All the dynamic performance can be determined, avoiding any human mistakes. Thus the consistent quality and excellent performance of each product can be guaranteed.
