ABSTRACT:
An articulated fire truck (T) has an extendible and retractable boom (11) mounted on the truck and extendible to a height above the ground where a fire is burning within a building (B). A drill assembly (1) is affixed to the end of the boom for drilling through a sidewall of the building into the building's interior. The drill assembly is maneuverable to drill straight through the sidewall as well as up and down and sideways so to provide an opening into the interior of the building sufficiently large that a nozzle attached to the drill assembly can readily spray water or a fire retardant material into the interior to extinguish the fire. The drill assembly has drill bits (100) located completely about the circumference of the drill assembly to facilitate up-and-down and side-to-side cutting to more quickly penetrate into the building's interior.
