Bosch Speed Clean HCD2084 Dust Extraction Hammer Bit, 1/2 in Dia, 13 in OAL, 25/64 in Dia Shank, SDS Plus Shank

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 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.
