Hole Brush 19mm dia x 400mm long

Description

Hole Brush 19mm dia x 400mm long is a cleaning brush for clearing dust and debris from drilled anchor holes. Chemical and mechanical anchors need a clean hole to bond or grip properly, and dust left behind after drilling weakens that bond no matter how good the anchor itself is. This brush is sized to match 19mm diameter holes and its 400mm length reaches deep into the hole to scrub the walls clean before an anchor goes in. Tradies and installers use it as a standard step in anchor installation, alongside a blower pump to clear the loosened dust out completely, wherever a reliable, code-compliant anchor bond matters.
