Core barrel

    core barrel, roller bits core barrel, core barrel with round shank chisel teeth,

Core Barrels are used for cutting an annular ring in rock or concrete (also reinforced concrete). The centre core is usually broken with chisel, rock auger or cross-cutter. The advantage of a core barrel is the concentration of the crowd force and torque on a small ring of cutting teeth. The diameter series of HM core barrels are standard sizes. Other lengths and diameters can be supplied on request.
