Roller Bits Core Barrel Foundation Piling Heat Treatment Different Size

Core Barrels with Roller Bits are used to cut an annular ring in rock or concrete or reinforced concrete,they adopt the high-carbon steel and special drilling bits angle to keep the drilling strength and efficiency.

Drilling core barrel with roller bits drilling rock Core with hard facing strip for durable use life,they are used to cut a ring in rock or concrete, mostly to initiate the borehole.

Core barrel with roller bits are 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. All related accessories in the barrel are subjected to "heat treatment" process, which increase the strength and wear resistance of the product.

2. Cutting ring with roller bits and releases the internal stress of rock.

3. Drilling with the method of rolling and squeezing can increases the anti-wear ability of the barrel.

4. Small barrel facilitates the coring operation; large barrel performs stage breaking.

5. Applicable for very strong rock formations with compressive strength greater than 100Mpa.

Applicable for very strong rock formations with compressive strength greater than 100Mpa.
