Use these cordless handheld band saws when portability and ease of movement are a priority, such as when working overhead or on lifts and ladders. Handheld band saws cut by moving a rotating belt-like blade against the workpiece. As the blade rotates, the weight of the tool provides the force for the cut, reducing the amount of effort needed to cut through a workpiece. Battery-powered band saws don't require access to an AC power source, and they don't have cords to tangle or trip over. Battery-operated tools can often share batteries with tools of the same brand and voltage.
