Title
(EN) DIAMOND DRILL
(FR) FOREUSE AU DIAMANT
Abstract
(EN)
A drill intended to be used in concrete, with diameters of 0.5 meter and more, requires the prior drilling of a hole of 5 cm to bear a threaded shaft (32) of which one bevelled end is used as setting means in the work surface and as centering means for the drilling operation. The feed of the tool inside the surface to be drilled is controlled by a nut (28) which screws in the threaded portion of the shaft. The supply water fills a chamber formed by a drum (22) of the cutting saw and the surface to be drilled. The water is forced to circulate along the cutting surface and consequently improves the lubrication of the drill bit. With such drilling equipment, an operator may work alone in all directions, including the possibility to drill into a ceiling.
(FR)
Une foreuse à béton pour diamètres de 0,5 mètre et plus nécessite le perçage antérieur d'un trou de 5 cm pour appuyer un arbre fileté (32) dont un bout en biseau sert de moyen de calage dans la surface de travail et à centrer le forage. L'avance de l'outil à l'intérieur de la surface à forer est contrôlée par un écrou (28) qui visse dans la partie filetée de l'arbre. L'eau d'alimentation remplit une chambre formée par le tambour (22) de la scie emporte-pièce et la surface à forer. L'eau est forcée à circuler le long de la surface de coupe et par conséquent facilite la lubrification du trépan. Avec cet équipement de forage un opérateur peut travailler seul dans toutes les directions incluant la possibilité de forer dans un plafond.
