Core barrels
Core barrel is a tool designed for drilling firm fractured rocks. During operation the soil can accumulate in the core barrel body as a core; after barrel pulling out of the well the soil is tapped out through the windows in the body and the roof. «PTC «ERDE TOOLS» has the capacity to manufacture core barrels with diameters of 350 mm up to 2,000 mm for any drilling rigs with kelly boxes of 100*100 mm to 200*200 mm.
Core cutters
Core cutter is a tool designed for cutting holes through mass concrete and thick rocky soil layers. In the course of the work, soil in the form of a core can accumulate in the core cutter body; after cutter pulling out of the well, the soil is tapped out through windows in the body and roof.
