Claims (3)

1. Способ вторичного использования буровых долот, включающий отбраковку вышедших из строя долот, промывку их в керосине и очистку, отличающийся тем, что, шарошки отделяют от лап, и к лапам для усиления приваривают накладки, фрезеруют радиальные пазы и сверлят перпендикулярно к ним отверстие под палец, затем в паз вставляют породоразрушающий диск и соединяют с папой посредством пальца, для свободного вращения диска в пазу.1. The method of reuse of drill bits, including the rejection of failed bits, washing them in kerosene and cleaning, characterized in that the cutters are separated from the paws, and pads are welded to the paws for reinforcement, the radial grooves are milled and a hole perpendicular to them is drilled under them finger, then a rock-cutting disk is inserted into the groove and connected to the father by means of a finger, for free rotation of the disk in the groove. 2. Способ вторичного использования буровых долот по п.1, отличающийся тем, что, ось фрезерования радиального паза в лапах может изменяться на угол α 0-20o в сторону против часовой стрелки и определяется физико-механическими свойствами разрушаемых пород, увеличиваясь с возрастанием коэффициента крепости породы.2. The method of reuse of drill bits according to claim 1, characterized in that the axis of the milling of the radial groove in the paws can change by an angle α 0-20 o in the direction counterclockwise and is determined by the physicomechanical properties of destructible rocks, increasing with increasing coefficient fortresses of breed. 3. Способ вторичного использования буровых долот по п. 1, отличающийся тем, что, породоразрушающий диск армируют зубками или штырями из металлокерамического твердого сплава. 3. The method for the secondary use of drill bits according to claim 1, characterized in that the rock cutting disk is reinforced with teeth or pins made of cermet carbide.
