With the Spit 055832 cleaning kit, you ensure maximum bond strength for chemical anchoring in concrete or masonry. Leftover drilling dust compromises injection mortar adhesion, but this complete manual set allows you to clean drilled holes thoroughly. Four round brushes with diameters of 11 mm, 15 mm, 26 mm, and 30 mm cover standard hole sizes. Thanks to the included extension rod and T-handle, you can reach deeper boreholes with ease, while the manual blow-out pump quickly expels loose debris. Everything is neatly stored in a robust carrying case, keeping your essential cleaning tools organized and ready for every job on the construction site.
