A fire fighting tool is described which is capable of both penetrating the wall of an enclosure, and dispensing a fire fighting agent into the interior of the enclosure. A drill bit or other penetrating device is carried at the forward end of an elongate shaft which is connected at its rear end to a drill motor or other appropriate actuating device. The shaft is surrounded by a barrel which receives a fluid fire fighting agent and includes a series of outlet openings at its forward end through which the agent is dispensed. The shaft is thus surrounded and cooled by the agent during the penetration operation. A leaky bearing is provided at the forward end of the barrel, and is specially configured along with the shaft and drill bit to induce a leakage of agent through the bearing and onto the bit and surrounding enclosure wall during drilling, thereby cooling the various parts and lessening the risk of an explosion. The barrel is designed to hold the tool in place once it has been inserted into the enclosure.

A fire fighting tool for extinguishing a fire within an aircraft, building or other walled enclosure, comprising: a housing adapted to receive a fluid fire fighting agent, an outlet barrel extending from the housing and adapted to receive a fire fighting fluid therefrom, the portion of the barrel distant from the housing including means for dispensing fluid from within the barrel, a solid, thermally conductive shaft extending through the barrel and carrying a penetrating means forward of the barrel the shaft forming a thermally conductive shaft and penetrating means, and controllable actuating means engaging the shaft to actuate the penetrating means, the penetrating means when actuated being adapted to penetrate an enclosure wall to admit the dispensing means of the barrel into the enclosure, the barrel being adapted to transmit fire fighting fluid around the shaft from the housing to the dispensing means, whereby the shaft acts as a thermally conductive heatsink to dissipate the heat generated by the penetrating means.
