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. 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.
