A tool for driving and setting nail-pin anchors and anchor bolts into concrete, the tool using the percussive action of a rotary hammer drill. In particular, example methods may provide for detecting a first touch or drag event, receiving a message indicating a second touch or drag event from a nearby device occurring during the first touch or drag event, creating a join event, and providing for transmission of the join event to the nearby device. In addition ignition timing for gas combustion is advanced to improve FCE while maintaining lower nitrous oxide emissions.
