Borehole brush – step brush
Cleaned drilled holes are the prerequisite for optimal adhesive mechanisms. Borehole brushes are used for the fine cleaning of boreholes for plastic anchors as well as when bonding solid and hollow brick. The cleaning of the drill holes increases the adhesive force of the dowels and is absolutely necessary for professional bonding with composite mortar. If the borehole wall is not cleaned, the adhesive values drop to 50% and below.
