Abstract

SE REFIERE A UN ENSAMBLAJE DE ESCARIADOR PARA ENSANCHAR UN AGUJERO PILOTO PERFORADO O PARA ENSANCHAR UN AGUJERO QUE HA SIDO ENSANCHADO EN UNA PRIMERA ETAPA EN UNA OPERACION DE PERFORADO DENTRO DEL AGUJERO, EN DONDE EL ENSAMBLAJE DE ESCARIADOR INCLUYE UN VASTAGO PARA LA UNION DEL ESCARIADOR AL EXTREMO DE UN TALADRO MARTILLO DENTRO DEL AGUJERO Y UN CABEZAL CONICO DE TALADRO O CORONA; CARACTERIZADO PORQUE EL CABEZAL CONICO DEL ESCARIADOR ESTA DIVIDIDO EN TRES SEGEMENTOS LOS CUALES TERMINAN CON UNA SUPERFICIE TERMINAL TRANSVERSAL QUE CONECTA DIRECTAMENTE DICHOS SEGMENTOS CONICOS. ASI MISMO TRES DE DICHOS SEGMENTOS INCLUYE BOTONES DE TALADRO QUE ESTAN DISPUESTOS EQUIDISTATEMENTE DEL EJE CENTRAL DEL CABEZAL DEL TALADROREFERS TO A REAMING ASSEMBLY TO WIDEN A DRILLED PILOT HOLE OR TO WIDEN A HOLE THAT HAS BEEN WIDENED AT A FIRST STAGE IN A DRILLING OPERATION INSIDE THE HOLE, IN WHICH THE ASSEMBLY OF THE ESCARI DRILL IS INCLUDED. END OF A HAMMER DRILL INSIDE THE HOLE AND A CONICAL DRILL OR CROWN HEAD; CHARACTERIZED BECAUSE THE TAPERED HEAD OF THE REAMER IS DIVIDED INTO THREE SEGMENTS WHICH END WITH A TRANSVERSE TERMINAL SURFACE THAT DIRECTLY CONNECTS SAID CONICAL SEGMENTS. ALSO THREE OF SUCH SEGMENTS INCLUDE DRILL BUTTONS THAT ARE EQUIDISTANTLY ARRANGED FROM THE CENTRAL AXIS OF THE DRILL HEAD
