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. Protruding bits will break easily. The outward and inward roller bit should overlap by about 120mm to 140mm. Too much overlap will cause the inner circle to wear out too easily.

A Core Barrel with Roller Bit is made of high carbon steel and a special bit angle. Its sharp teeth provide increased penetration rates and reduce drilling chatter. Moreover, it reduces the strain on the drilling rig. Other sizes of this tool are available, including Kelly Box diameter 200mm, Cylinder Thickness 40mm, Helight 400mm, and Cutting Ring thickness 20mm. They can also be customized according to rock formation and project requirements.

The core barrel is a special type of auger used for cutting annular rings of reinforced concrete or rock. It is used for cutting the center core of rock and concrete. It works by concentrating torque on a narrow ring of cutting teeth. This tool is more efficient than the rock auger. And its versatility makes it ideal for a variety of construction projects. Once you've found the right tool for the job, you'll never regret it!

If you're looking for a faster and more efficient method to drill into hard rock, core barrels may be a great choice. The tool cuts an annular slot through hard rock and extracts the core in one piece. The resulting hole is a hollow shaft that is perfect for drilling in hard rock and removing it. The core barrel is also more cost-effective than drilling buckets. It can cut a 100MPA-strong rock with deep cracks.
