Drill bit assembly for bomb deactivation and other applications

Abstract

A drill bit assembly is formed to drill into an object while reliably conducting a fluid onto a point being drilled and subsequently into the object being drilled includes a sleeve that is bored and threaded and cut flush to substantially mate with the outside surface of a conducting tube. An elbow connector is mounted within the sleeve and receives a fluid from a tube coupled thereto. The drill bit assembly further includes a telescoping conduction tube for conducting fluid about the drill bit as it rotates and into an opening created by the drill bit. The telescoping conduction tube axially slides about the conduction tube and also conducts fluid about the drill bit while slidingly mating with the conduction tube to minimally leak the fluid. The drill bit assembly further includes a telescoping outer tube that defines a 45 degree cut at a drilling point end of the drill bit, wherein the 45 degree cut flushes cutting debris away from the drill bit thereby substantially reducing clogging of the fluid conduction tube. The drill bit assembly may be used in connection with any object being drilled for which temperature or sparking is to be reduced or eliminated.
