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.It is a mine peak having an elongated steel body, with an agglomerate of diamonds as a cutting point, the point being supported on a material harder than the body, with the improvement consisting in that the material is a hardened metal and in that the agglomerate is coated longitudinally in a recess of hard metal.
