The Smart-Bit for Fiber Cement Board is a tungsten carbide tipped pre-drilling and countersinking tool. Like other products in the Smart-Bit line, it is designed to create a perfect hole and fit for matching fasteners. The SmartBit for Fiber Cement is the first tool that makes it possible to pre-drill and countersink in one step at a consistent depth, without damaging the work surface. The Smart-Bit tool features a free spinning stop collar, which controls the depth of the drill and countersink. The stop collar is fitted with a rubber O-ring to prevent surface damage or marking.
