Excerpt: The Milwaukee M18 Sawzall (2620-22) is just plain fun to use. It’s cordless, which opens up a wide range of opportunities for use, and weighs just shy of 8 lbs with the battery. The weight puts it surprisingly close to its corded brethren. What it gives up in power (and lack of orbital action) it makes up in strokes per minute. In fact, it has more SPM than the corded 11-15 amp models Milwaukee offers.
