Abstract

La presente invención se refiere a una broca de taladro, caracterizada porque comprende un cuerpo de broca de taladro que tiene una porción de cuerpo principal y una pluralidad de patas que se extienden hacia abajo de la misma, el extremo inferior de cada una de las patas tiene una extremidad de ahusamiento relativamente delgada conocida comúnmente como la porción o extremo de revestimiento o forro interior, una pieza de corte o cortador montado giratoriamente sobre cada pata, los cortadores, después del giro del cuerpo de broca, definen una trayectoria circular de corte, el diámetro externo de los cortadores fornan el diámetro externo de la broca de taladro; y caracterizado porque: la porción de cuerpo principal además incluye una asa o prominencia estabilizadora integralmente forjada sobre la misma directamente por arriba de cada pata, cada prominencia se extiende radialmente hacia afuera desde la porción de cuerpo principal hasta sustancialmente el mismo diámetro que la trayectoria circular de corte; y medios de canales de flujo rebajados a lo largo de los bordes inferior y lateral de cada prominencia para mejorar el flujo del flúido desde alrededor de cada porción de extremo de revestimiento interior hacia arriba alrededor de cada prominencia o asa estabilizadora.The present invention relates to a drill bit, characterized in that it comprises a drill bit body having a main body portion and a plurality of legs extending downwards thereof, the lower end of each of the legs has a relatively thin taper end commonly known as the inner liner or liner portion or end, a cutter or cutter rotatably mounted on each leg, the cutters, after rotation of the drill body, define a circular cutting path, the outside diameter of the cutters shape the outside diameter of the drill bit; and characterized in that: the main body portion further includes an integrally forged stabilizing handle or protrusion thereon directly above each leg, each protrusion extending radially outward from the main body portion to substantially the same diameter as the circular path. cutting; and recessed flow channel means along the bottom and side edges of each prominence to improve fluid flow from around each inner liner end portion upward around each prominence or stabilizer loop.
