Abstract
Process for the manufacture of drills, characterized by the fact of preforming a grooved cutting portion with one of its ends arranged to constitute the cutting end of the bit and with a lubricating conductor passage that extends through it and to one side of its axis, joining to the end of said cutting portion, coaxially with it and at the extremity opposite its cutting end, a portion of tube arranged to form a tubular portion carrying the drill bit, so that its drill it constitutes a longitudinal and central passage, lubricant conductor, machining a groove in said carrier portion of the rod so that its end opens into the adjacent end of a groove of the cutting portion, said groove being the carrier portion of the reed less shallow than the adjacent groove of the cutting portion and having a cross-section whose profile is convexly curved in its central part, and a lubricating conductive transverse port being inserted in the drill, substantially in the junction joint of the shank carrying and cutting portions, to intercommunicate the lubricant conductive passages of said portions.
