Bosch 3/4 In. x 21 In. 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 percent 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 SpeedX? SDS-max? bits. Solid carbide tips are embedded in a steel head with robust four-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%. A rubber adapter is provided with every Bosch Speed Clean? bit. The system also reduces airborne silica dust， a known contributor to respiratory illnesses.
