Descriptions:
1.Core barrels are used to cut an annular ring in rock or concrete or reinforced concrete.
2.The center core of the rock or concrete is usually crushed with rock auger. The most important advantage of a core barrel is that it assists to concentrate the torque and crowd force on a small ring of cutting teeth.
