The 6519-31 is one of Milwaukee’s newest members to the Sawzall family. This saw is powered by a 12 Amp motor that gives it 0-3,000 strokes per minute, which makes it great for cutting through just about anything. Plus if you use the Ax Blade, you will rip through even more. The stroke length is 1-1/8″ and uses the famous Quik-Lok blade clamp. The Quik-Lok system is great as it is tool free, but once you put a blade in the saw, it stays in place, even under the heaviest conditions. Also I have never had a blade not come out as I have with competitor saws. Milwaukee uses a gear protecting clutch to extend the gear and motor life. This type of protection absorbs the impacts you can receive when making cuts.
As with the other Milwaukee sawzalls, there is nice over molded grip on the front for maximum grip. The front grip is a little different as Milwaukee redesigned the front grip area for better comfort. There is also a counter weighted mechanism which helps reduce vibration for a smoother operation. The smoother operation means it can be more safe because the user will not get fatigued as quick. Speaking of fatigued, this only weights 7.1 lbs. So the saw is not heavy and can be used for longer periods of time.
A couple things this saw does lack is an adjustable shoe and speed control. So if those are important to you, take a look at one of their other models. This model also comes with a nice carrying case to protect your Sawzall when not in use. They also have the model 6519-30. The only difference between these two saws is the 30 does not come with a carrying case, while the 31 does.
