Abstract
Il s'agit d'un pic de mine ayant un corps allongé en acier, avec un aggloméré de diamants comme pointe de coupe, la pointe étant appuyée sur un matériau plus dur que le corps, avec le perfectionnement consistant en ce que le matériau est un métal dur cémenté et en ce que l'aggloméré est enrobé longitudinalement dans un évidement de métal dur.
