Abstract
A foot attachment for a pneumatic rotary tool is configured to be attached to a nose portion of the housing of the tool. The rotary tool includes a housing that defines an air flow channel. A nose portion of the housing defines an air flow inlet for the air flow channel. The foot attachment includes a shroud portion that extends from the nose portion of the housing and surrounds a working space in front of the nose portion of the housing. The shroud portion defines at least one tangential opening that directs air flow into the shroud portion along a tangent such that a vortex is generated within the working space.
