800mm dia grab type core barrel used for deep foundation piling work
grab type core barrel ,grabing style core barrel main use for gravel , boulders
Core Barrels are used for cutting an annular ring in rock or concrete (also reinforced concrete). The center core is usually broken with round shank picks, rock auger or cross cutter. The advantage of using the core barrel is the concentration of the crowd force and torque on small ring of cutting teeth.

ore barrel with cross cuter Ø1000MM kelly box 130 x 130 suitable for drilling rig bauer soilmec
core barrel with cross cuter is mainly used to break rock cores which remain in the borehole after using a core barrel. The core is broken with round shank chisels. The cuttings are then removed with buckets. It is also suitable for drilling hard, jointed rock (<100 MPa) and for penetrating through layers containing boulders. Main application Main application Hard rock formations (up to 100 MPa)
Main application:  Cross Cutter is designed mainly to used for break rock cores which remain in the borehole after using a core barrel. The core is broken with round shank picks. Then cuttings are removed with heavy duty buckets. It is also suitable for drilling hard, jointed rock (<100
