Abstract: A method and system for wirelessly tracking power tools and related devices to aid with inventory management and to help minimize, prevent, and recover misplaced or stolen tools throughout the job site. The tools and/or batteries include wireless transmitting capabilities (e.g., an ISM unit) to transmit data to a fob, puck repeater, and/or gateway over an ISM network. The gateway is operable to translate and output the ISM communications over a cellular network to a remote monitoring unit, such as a personal computer or smart phone. Additionally, the gateway is further operable to translate and output cellular communications from the remote monitoring unit to ISM communications over the ISM network. A wireless tethering system and method is also disclosed whereby an ISM battery places a power tool in a lock-out or limp mode after the ISM battery remains outside of ISM communications for a prolonged period of time.

Abstract: A cutting tool including a body, a blade, a feed shaft, and a locking member. The body defines an axis and is adapted to be received by a spindle of a power tool. The blade is removably supportable on the body and rotatable about the axis for cutting a workpiece. A feed shaft is removably supportable in the body and rotatable about the axis for engaging a workpiece, the feed shaft being mountable in the cutting tool to engage and at least partially restrain the blade. The feed shaft further includes an opening transverse to the axis. The locking member is engageable with the body and with the opening in the feed shaft. Advancement of the locking member into the opening tightens both the blade and the feed shaft to the body.

Abstract: A method for conducting an operation including a power tool battery pack. The battery pack can include a housing, a first cell supported by the housing and having a voltage, and a second cell supported by the housing and having a voltage. The battery pack also can be connectable to a power tool and be operable to supply power to operate the power tool. The method can include discharging one of the first cell and the second cell until the voltage of the one of the first cell and the second cell is substantially equal to the voltage of the other of the first cell and the second cell.
