Must Have Bosch HCSTP2083 1/2 In. x 1-11/16 In. SDS-plus Stop Bit

Key masonry applications, ranging from suspension of struts for electrical and air systems to hardware for overhead piping and sprinkler systems, Bosch stop bits bring precision, speed and professionalism to a task once marked by guess work and drill bits marked with tape. Applications are designed to incorporate drop-in anchors. A steel collar on each bit marks the precise depth of the hole. Once the collar is flush with the concrete surface, the correct depth is reached.
