Core Barrel With Doubel Shell

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.

Coring Barrel

1.Movable square head, lock buckle is formed by key and key sleeve.
2.The square head is reversed and can be pressed down, the double doors are attached to the barrel wall, and the forward rotation can be drilled.
3.The square head is reversed and can be lifted up, the double doors are held together, and the soil is unloaded when reversed and pressed.

Flat Soil Auger

1.Soft to stiff silt and clay, loose to medium dense sand and gravel.
2.The single cut and double cut augers with side cutters are suitable for drilling in hard clay, silt and medium to high dense sand and gravel.
3.Single cut auger are recommended up to coarse gravel.
