Solid Core Rotary Brush System w/Push Button Locks

Your drill with clutch rotates the inner cable only, delivering rotation to the brush head. Package includes cable assembly and seven brush heads. Four are nylon brush heads ( 4″, 8″, 12″, 18″) and three are silica carbide brush heads (8″, 12″, 18″). The silica carbide brush heads are more abrasive and enable you to clean even heavily compacted debris from duct interior. Solid core design offers medium flexibility, allowing brush head control while flexing into corners and edges. Includes replacement inner core.  Available in 7′, 20′ and 33′ lengths’. Color may vary.
