Cone roller cutter used for pile foundation drilling, used for core barrel in pile foundation construction
The core tube is used to cut annular rings in rock or concrete or reinforced concrete. The central core of rock or concrete is usually crushed with a rock auger. The most important advantage of the core barrel is that it helps to concentrate torque and squeezing force on a small circle of cutting teeth.
1- Core barrel with bullet head (suitable for solid rocks below 100Mpa or rock with deep cracks)
2- Core barrel with roller bit (suitable for very strong rock formations with compressive strength greater than 100Mpa)
