# Rotary Wrecking (DD-450)

> Chimney sweeps and relining crews remove old clay flue tiles and mortar with rotary tools lowered down the flue on rods or cables. A motor spins chains or carbide- or diamond-tipped heads that break or grind away the liner, clearing room for a new one. The footage shows a rotary tool breaking tiles inside a chimney.
