Dust Collection During Drilling The RUBI® Zero Dust Guide is a vacuum attachment designed to collect dust and debris directly at the drilling area. Removing debris as it is generated improves visibility around the hole and reduces airborne dust during drilling. Dual Air Chamber Suction A dual air chamber system maximizes suction capacity for effective dust collection. The rubber base seals against the work surface to help contain dust and prevent particles from escaping around the attachment. Vacuum Hose and Drill Bit Compatibility The Zero Dust Guide accommodates drilling up to 2-3/4" in diameter and connects to vacuum hoses from 1" to 1-1/2". An additional brush is included for use with larger-diameter drill bits while maintaining effective suction.
