Abstract
A guard for a power-feed drill having a fluid inducer protects an operator from coming in contact with a rotating drive assembly. The drive assembly is enclosed by a cylindrical housing having a slotted opening through which a fluid inducer connection extends. The guard comprises a rotatable tube concentrically disposed within the housing and sleeved over the drive assembly so as to cover the opening presented by the slot. The fluid inducer connection passes through a helical groove in the tube.
