<p>Cleaning implement (300) apparatus for cleaning boreholes formed within various different substrates, such as, for example, concrete slabs, concrete blocks, bricks, or the like, comprises a first embodiment for use within a power-operated tool, such as for example, a roto-hammer (322) type power tool for drilling boreholes within concrete or brick substrates, while a second embodiment of the apparatus comprises a manually-operated tool (400). The first embodiment comprises a bit member (316) having a slotted drive shank (SDS) (320) connection for mounting within the chuck mechanism of the roto-hammer type power tool. In this manner, the same roto-hammer type power tool can be used for both drilling the borehole within the substrate as well as for cleaning the borehole by exchanging the cleaning implement for the drill bit.</p> |
