A cutting tool includes a tool body having a first end engageable with a workpiece and a second end engageable with a spindle of a power tool. A blade extends outwardly from the first end of the tool body and including a cutting edge, the cutting edge being engageable with a workpiece to cut the workpiece. A bit, including a drive shaft and a cutting end extends along an axis of the tool body. The drive shaft extends axially outwardly beyond the first end of the tool body and terminates at the cutting end. The cutting end has a maximum cross-sectional width greater than a maximum cross-sectional width of the drive shaft, and an axial distance from the first end of the tool body to the cutting end is greater than a maximum cutting depth of the cutting tool.

A system and method for battery protection. In some aspects, a method of conducting an operation including a battery pack, includes the acts of monitoring a first battery pack condition at a first monitoring rate, determining when a second battery pack condition reaches a threshold, after the second battery pack condition reaches the threshold, monitoring the first battery pack condition at a second monitoring rate, the second monitoring rate being different than the first monitoring rate. In some aspects, a method of conducting an operation including a battery, the battery including a cell having a voltage, power being transferable between the cell and the electrical device, a controller operable to control a function of the battery pack, the controller being operable with a voltage at least one of equal to and greater than an operating voltage threshold, the cell being operable to selectively supply voltage to the controller, includes the act of enabling the controller to operate when the voltage supplied by the cell is below the operating voltage threshold.
