The Milwaukee 0719 Cordless V28 Sawzall Reciprocating Saw uses a high powered Milwaukee built motor to deliver faster cutting and performance. Powering the 0719 is the revolutionary 28 Volt Lithium-Ion battery pack, exclusively from Milwaukee. The 28 Volt battery pack weighs less than an 18 Volt pack, yet delivers two times the run-time, making this the ideal solution in cordless reciprocating saws. The battery is positioned so that it does not interfere with plunge cutting capabilities. This Sawzall(r) saw has a 1-1/8 in. stroke length that delivers speed. The variable speed trigger delivers two levels of speed range: 0-2000 spm for metal cutting and other hard materials and 0-3000 spm for cutting in wood and other materials encountered. The gear protecting clutch protects the tool against impact, delivering on the legendary Sawzall(r) durability.
