Abstract
A dust extraction device () for a rotary power tool having an elongate rotating drill bit () for operating on a work surface includes a casing () having an inlet () and an outlet () and defining an interior cavity (). A fan element () having a plurality of impellers () and a central hub () is adapted for rotation within and independent of the casing for inducing air flow within the casing from the inlet to the outlet when the fan element rotates, the hub being adapted for engaging the drill bit () in a manner that permits rotation of the hub as well as axial movement of the drill bit relative to the hub during rotation of the drill bit. Rotation of the drill bit results in air flow to remove debris from the work surface to the outlet without rotating the casing.
