Features:
1.The inner shell starts drilling first, the outer shell follows.
2.The cutting rings are attached with 21-70 rock drilling bits, this design releases the internal stress of rock.
3.These rock drilling bits perform stage breaking and foundation drilling.
4.The small inner core barrel facilitates the coring operation, the large outer barrel performs stage breaking.
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.
