Test tube brush recommended for cleaning drilled holes in concrete, brickwork and blockwork when fitting our ground anchors. This can help to improve the strength of the bond when using resin fixings, and likewise when using shield anchors (expanding bolts).
Suitable primarily for hole diameter 12mm, and (with additional push/pull strokes), for 16mm.
Tip: You may find it is easier to withdraw the brush by bending the wire handle at its mid-point, or by poking a screwdriver through the 'eye' at the top of the handle. Take care not to pinch your fingers!
