Définitions

anglais: A rotary boring bit consisting of two to four-cone-shaped, toothed rollers which are turned by the rotation of the drill rods. They are used in hard rock in oil well boring and other deep holes down to 15,000 feet and more. Although their penetration speed is somewhat slow, roller bits last longer which is a very important factor in deep drilling.
