Bosch 3/4 in. x 21 in. Carbide SDS-MAX Speed Clean Dust Extraction Bit

Bosch Speed Clean drill bits are built using a solid piece of steel with a dust channel that's milled to Bosch specifications to extract dust while drilling, creating 25% greater drilling speed. The dust extraction bit system saves time, saves money and produces 90% less dust than traditional drilling methods. The bit life is comparable to the life of Bosch Bulldog SDS-plus bits. Solid carbide tips are embedded in a steel head with robust 4-cutter geometry enhancing bit speed and life. The Speed Clean bit, connected to vacuum system, installs adhesive anchors up to 50% faster when compared with the standard hand-cleaning method. A proprietary Bosch design allows dust and debris to be removed through the milled center of the bit. The system is optimized for adhesive anchoring applications, working with Simpson Strong-Tie Set-XP high-strength anchoring adhesive, which requires higher clean-hole standards. Dust reduction also increases drilling speed by 25%.|Hollow drill bit connects to a vacuum system to deliver up to 50% time savings versus the conventional drill-blow-brush-blow anchor-installation method|Faster drilling provides up to 25% greater drilling speed thanks to less dust and reduced friction|Great durability 1-piece design offers comparable life to Bosch Bulldog bits|Part of a dust-reduction engineered solution included rubber adapter and bit works with a vacuum system to manage airborne silica dust|Optimized for adhesive anchoring works with Simpson Strong-Tie SET-XP high-strength anchoring adhesive|Rubber adapter is provided with every Bosch speed clean bit|System also reduces airborne silica dust, a known contributor to respiratory illnesses|Dust reduction, which reduces friction on the bit, also increases drilling speed by 25%
