Abstract
Una broca de perforación con canal para fluido comprende un cabezal de corte asegurado en forma desmontable a una espiga, que posee un eje longitudinal común y que comprende superficies periféricas de acople. Una porción de acople de la espiga que comprende una superficie de fijación de espiga que se reduce gradualmente hacia delante se forma en el extremo frontal de la espiga, y una porción de acople del cabezal de corte comprende una superficie de fijación del cabezal de corte que se reduce gradualmente hacia delante se forma en un extremo posterior del cabezal de corte. Tanto la porción de acople de la espiga como la del cabezal de corte se extienden sobre un ángulo periférico de acople omega mayor a 180°. La espiga y el cabezal de corte se ensamblan mediante el posicionamiento de la cara delantera del cabezal de corte en frente de la cara trasera de la espiga, la inserción mediante deslizamiento de la porción de acople del cabezal de corte en la porción de acople de la espiga lateralmente al eje de rotación A y la rotación del cabezal de corte en relación a la espiga en una dirección opuesta a la dirección de rotación R de manera que la porción de acople del cabezal de corte y la porción de acople de la espiga se traban coaxialmente.A drill bit with fluid channel comprises a cutting head secured detachably to a spike, which has a common longitudinal axis and which comprises peripheral coupling surfaces. A spike coupling portion comprising a spike fixing surface that is gradually reduced forward is formed at the front end of the spike, and a coupling portion of the cutting head comprises a fixing surface of the cutting head that is gradually reduced forward is formed at a rear end of the cutting head. Both the spike coupling portion and the cutting head portion extend over a peripheral angle of omega coupling greater than 180 °. The spike and the cutting head are assembled by positioning the front face of the cutting head in front of the rear face of the pin, the insertion by sliding of the coupling portion of the cutting head into the coupling portion of the pin laterally to the axis of rotation A and the rotation of the cutting head relative to the pin in a direction opposite to the direction of rotation R so that the coupling portion of the cutting head and the coupling portion of the pin are locked coaxially.
