Features:
1.Cutting ring with rock drilling bits helps release the internal stress of rock
2.When drill in the full fracture rock layer, crossing cutter makes it easy to carry soil
3.Kelly box: 130mm,150mm,200mm(optional)
4.Barrel adopts spiral wear-resistant strips for anti-attrition to prolong the service life
5.Many alloy teeth are used for higher drilling efficiency
6.Heightened design with high construction efficiency, reducing construction cost
Descriptions:
1.Core barrels are used to cut an annular ring in rock or concrete or reinforced concrete.
2.The center core of the rock or concrete is usually crushed with rock auger. 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.
