The Bosch Speed Clean bit is connected to a vacuum system to deliver up to 50% time savings versus the conventional drill-blow-brush-blow anchor installation method. The system reduces human error for greater consistency， which helps control overall installation costs. Bosch Speed Clean bits are available for either SDS-plus or SDS-max hammers. With solid carbide tips are embedded in a steel head， these bits are comparable in bit life with SpeedX and Bulldog bits.
