Rock Drilling Tools Core Barrel Bullet Bits Roller Bits Drilling Rig Parts

Drilling core barrels are used to cut a ring in rock or concrete and releases the internal stress of rock while cutting inside. The center core of the rock or concrete is usually crushed with rock bits.

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. Rock drilling bits perform stage breaking and drilling

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

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