ABSTRACT:
A dust collection unit suitable for use with a hand held drilling and/or hammering tool, comprising a shroud (34) which is adapted to extend around a tool or bit (24) of such a hammering and/or drilling tool so as to collect dust in an airflow passing through the shroud which dust is generated by such a tool or bit. A tube like extension sleeve (28) extends forwardly from the shroud, with respect to such a tool or bit, which extension sleeve (28) is tapered at its forward end so as to have a forward rim which fits into a corner of a surface to be worked. A slideable sleeve (54) is slideably mounted on the extension sleeve so as to move between a retracted position in which the tapered forward rim of the extension sleeve (28) is engageable with a corner surface to be worked and an extended position in which a forward rim of the slideable sleeve (54) is engageable with a surface to be worked.
