Two kinds of core barrels for bore pile drilling

There are many types of core barrels, we would like to introduction the kind of core barrel that used in foundation bore pile drilling. The two core barrels used for piling on site construction are the same in shape, workmanship and material. They are divided into core barrel with bullet teeth and core barrel with roller bits according to the different drill bits used. The diameters of these two core barrels are both 600-2500mm, of course, we can also customize them according to customer needs.

Core barrel with bullet teeth is used for cutting an annular ring in rock or concrete ( also reinforced concrete), core barrel with roller bits is used in very strong rock formations ( compressive strength> 100Mpa).

Advantages of UNIMATE core barrels: High quality raw materials and high steel strength, simple operation, and UNIMATE core barrels drilling tools have high wear resistance, long using life. Besides, UNIMATE core barrels are suitable very well for high hardness formation conditions.
