How to use the drilling tools correctly on deep foundaion drilling projects.

A hard rock drill core barrel is a specialized tool used for cutting annular rings in rocks or reinforced concrete. These specialized cutting tools have a small ring of cutting teeth that are used to increase the torque of the cutting tool. Core barrels are often equipped with tungsten carbide round

A core barrel with roller bit is an excellent choice for hard rock drilling. It offers maximum cutting efficiency and ease of installation. The roller bit has an angle of 5-6 degrees to maximize cutting surface while protecting the vulnerable shirttail part. Its height and round circle should match.

A Rock auger is an attachment for a drill that utilises a rotating pick tooth to maximize penetrative capacity. Using this unique design, rock augers are capable of drilling through ground that would otherwise be inaccessible to a standard auger. Typically made of high-grade steel, a rock auger has
