The Bosch Speed Clean™ bit connected to vacuum system cuts hole-drilling process by 50% less versus the standard hand-cleaning method. A proprietary Bosch design allows dust and debris to be removed through the milled center of the bit. Dust reduction, which reduces friction on the bit, also increases drilling speed by 25 percent. A rubber adapter is provided with every Bosch Speed Clean™ bit. Bit life is comparable to Bulldog™ and SpeedX™ bits. System also reduces airbourne silica dust, a known contributor to respiratory illnesses.
