Roller Drilling Tools Core Barrel Roller Bits Piling Tools Hard Formation
Core Barrel With roller bits is used to cut a ring in rock or concrete, mostly to initiate the borehole.
Rock Drilling Core Barrels with Roller Bits adopt the high-carbon steel and special drilling bits angle to keep the drilling strength and efficiency.
Core barrels are generally divided into two types:
Core barrel with bullet bits (Applicable for strong rock up to 100Mpa or rock with deep cracks)
Core barrel with roller bits (Applicable for very strong rock formations with compressive strength greater than 100Mpa)
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.
The diameter series of buckets are standard sizes,other lengths and diameters can be supplied on request.

1. Cutting ring with roller bits and releases the internal stress of rock.
2. Drilling with the method of rolling and squeezing can increases the anti-wear ability of the barrel.
3. Small barrel facilitates the coring operation; large barrel performs stage breaking.
Applicable for very strong rock formations with compressive strength greater than 100Mpa.
