Abstract
Rotary cutting tools normally throw out chips and other particles from the surface or edge being cut. According to this invention, an exhaust hood, arranged to be connected to an exhaust system, having a bristle skirt is mounted to enclose an area about the tool, a strong jet of air from a jet nozzle put through the hood is directed toward the cutting portion of the tool and at the stream of chips being thrown off to disburse all of the chips and particles up into the air stream being exhausted from the hood causing them to become airborne. The air stream entering the hood through the interstices in the skirt and rushing across the hood and out through the exhaust port will so completely capture the airborne chips and particles that none will escape into the general atmosphere of the machine room.
