Title
(EN) EJECTOR DRILL SYSTEM
(FR) SYSTÈME DE FORET À ÉJECTEUR
Abstract
(EN)
A drilling head for a tubular shank having an inside diameter and threads may comprise an axial body comprising a duct exiting through a first end; threads adjacent the first end corresponding to the threads on the shank and aligning the duct with the shank inside diameter; a bore from an outer surface of the body to the duct; and two axially extending approximately parallel and offset surfaces adjacent a second end; and an insert affixed between the offset surfaces, the insert comprising: a first face at least partially contacting one offset surface and a second face at least partially contacting the other offset surface; one or more cutting edges adjacent the first face, the second face, or both; and a cutting lip adjacent one or more cutting edges.
(FR)
L'invention concerne une tête de perçage pour une queue tubulaire présentant un diamètre intérieur et des filets pouvant comprendre un corps axial comprenant un conduit sortant via une première extrémité; des filets adjacents à la première extrémité correspondant aux filets sur la queue et alignant le conduit avec le diamètre intérieur de la queue; un alésage depuis une surface externe du corps vers le conduit; et deux surfaces décalées et approximativement parallèles s'étendant axialement adjacentes à une seconde extrémité; et une pièce d'insertion apposée entre les surfaces décalées, la pièce d'insertion comprenant : un premier côté entrant au moins partiellement en contact avec une surface décalée et un second côté entrant au moins partiellement en contact avec l'autre surface décalée; un ou plusieurs bords de coupe adjacents au premier côté, au second côté, ou aux deux; et un bec de coupe adjacent à un ou plusieurs bords de coupe.
