ABSTRACT:
An attachment for a rotating tool bit provides air flow in the vicinity of the work area without the need for separate vacuum or compressed air supplies. The device is mounted on the shaft of the rotating tool bit and provided with a plurality of vanes which direct airflow through a cylindrical housing towards or away from the work area. A central aperture provides resilient mounting of the attachment to the tool bit. The attachment is capable of providing suction as well as forced-air to the work area. A number of embodiments are disclosed for directing the exhausted air in different directions, depending on the application of the tool and operator orientation. A filter may be incorporated into the attachment in order to collect dust and debris carried away from the work area by the air flow.
