Bosch Precision Stop Bits Words: Dan Kamys/Public/News/20111003120000-1.jpg" width="600" height="338" border="0" alt="Bosch Stop Bits bring precision, speed and professionalism to a task once marked by guess work." />Bosch Stop Bits bring precision, speed and professionalism to a task once marked by guess work. In key masonry applications ranging from suspension of struts for electrical and air systems to hardware for overhead piping and sprinkler systems, Bosch Stop Bits are designed to 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. Bosch offers a complete line of five carbide-tipped steel bits that include 3/8-, ½- and 5/8-inch sizes. Depths range from 13/16- to 2 1/16-inch. The size and depth range of the products accommodates more than 80 percent of all requirements for drop-in anchors. The size and depth combinations prevent over-drilling and drilling into rebar, which allows the professional user to install drop-in anchors properly and securely. The bits take the place of the manual depth gauge on rotary hammers, a feature many users disable. Drill bit maximum speed is 1,100 rpm. For more information, visit www.boschtools.com.About: Tools
