Apparatus for cleaning boreholes within substrates
Cleaning implement 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 type power tool for drilling boreholes within concrete or brick substrates, while a second embodiment of the apparatus comprises a manually-operated tool. The first embodiment comprises a bit member having a slotted drive shank (SDS) 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.
1. A method for drilling and cleaning a borehole in a substrate, the method comprising: mounting a drill bit having a slotted drive shank (SDS) connection formed thereon to a roto-hammer type power tool so the drill bit is operatively connected to an SDS connection of a chuck of the roto-hammer type power tool and the chuck can rotate the drill bit while enabling the drill bit to move axially along a longitudinal axis of the drill bit; driving the borehole within the substrate by actuating the roto-hammer type power tool to rotate the drill bit; removing the drill bit from the roto-hammer type power tool after completing the drilling of the borehole; mounting a cleaning brush assembly to the roto-hammer type power tool so an SDS connection formed on the cleaning brush assembly is operatively connected to the SDS connection of the chuck of the roto-hammer type power tool and the chuck can rotate the cleaning brush assembly while enabling the cleaning brush assembly to move axially along a longitudinal axis of the bit member; inserting a free end of the cleaning brush assembly into the borehole, the free end of the cleaning brush assembly having one or more cleaning brushes disposed thereon; and actuating the roto-hammer type power tool to rotate the cleaning brush assembly to clean the drilled borehole.
