This Foredom® A-RB retractable bench brush is ideal for cleaning workpieces, work surfaces, tools and even clearing debris from a vacuum port. The brush offers two brushes: the larger brush (1-1/2"L x 1" dia.) is extended and retracted by twisting the housing, the smaller brush (3/4"L x 3/8" dia.) is extended and retracted by a slide built into the housing. The plastic housing, 5-1/4" long with brushes fully retracted, is lightweight but tough and durable; it takes up little space on the bench yet is ready in a snap when needed.
