A drill adapter for attaching to an air impact wrench. With attachment of the drill adapter, the air impact wrench can operate as a power drill for drilling bores in a workpiece. The drill adapter generally includes a body having a shaft receiving end and a drill chuck. The shaft receiving end includes a holding section sized and shaped for receiving the tool spindle or shaft of an air impact wrench. The drill chuck includes a plurality of jaws for clamping to a drill tool and tightening means for tightening or releasing the drill tool from the jaws. In operation, the tool spindle of a powered turning impact wrench is engaged within the holding section of the drill adapter. A drill tool is received in the drill chuck. When the impact wrench is fully engaged with the attachment described, the rotation torque output of the air impact wrench turns the drill adapter resulting in the air impact wrench operating as a power drill to form bores in a workpiece.
