HEMCO core barrels are specially designed to drill through very hard formations and permafrost. With tricon bits, the core barrels can be used to cut through rocks with UCS exceeding 100 MPa.

Diameters up to 2500 mm can be manufactured.

For wear protection, Hardox 450 or equivalent strips are used. 
We manufacture Core Barrels with round shank chisel teeth as well as tricon bits.
