Abstract
A chuck includes a generally cylindrical body having a nose section and a tail section. The tail section is configured to rotate with the drive shaft, and the nose section has an axial bore formed therein. The body defines an air passageway extending through the body between the axial bore and an area about the tail section. A generally cylindrically sleeve is disposed about the body and substantially encloses the area. It is configured to extend to a housing of the drill so that air from the fan is forced into the area, through the air passageway and into the axial bore.
