Powering the Lithium-Ion Cordless SAWZALL Reciprocating Saw Kit is the revolutionary 28V Lithium-Ion battery pack, exclusively from Milwaukee. The battery pack weighs less than an 18V pack, yet delivers two times the runtime, making this the ideal solution in cordless reciprocating saws. Plus, the battery comes positioned so that it doesn't interfere with plunge cutting capabilities. Other special features include a gear protecting clutch, the keyless shoe adjustment, which allows for better control in cutting and longer blade life, and the QUIK-LOK blade clamp that makes changing blades a snap. A comfortable, non-slip, soft grip handle provides for a better gripping surface and reduces vibration and fatigue.
