Milwaukee M18 Sawzall 2621-21 Review

It’s not too often that power tool companies go back to the drawing board and update current models, but that’s exactly what Milwaukee did with the new M18 Sawzall 2621-2. This model replaces the current “brushed” model 2620-20. The new model is said to have improved power and runtime.

Manufacturer’s like to claim their product is better than this or that so I took it upon myself to not only test the new tool as I usually do but to put those claims to the test by comparing it to the outgoing model. Individual tests showed that it was indeed a great performer but side by side is where you can really see the difference. You can definitely see the new model kicks butt when cutting sections of 2×4’s as the previous model moves along at a decent pace. The next test was cutting a 3-1/4″ x 3-1/4″ post and I was able to easily make 2 cuts with the new model while the older model made one cut.

What’s strange is that the new model has an inline cutting action versus the older model has more of an orbital cutting action and the SPM has been reduced from 3,200 to 3,000 on the new model, while the stroke length stays the same at 1-1/8″ on both. If you look at the stats on paper you would believe the older model is better suited at wood cutting due to more SPM and the orbital motion when cutting but that’s just not the case in real life.

The inline cutting action on the new model makes it a lot easier starting cuts into metal as the blade doesn’t jump around like it does on the older model when starting cuts. The new model is very good at cutting metal as can be seen in the video review in which I cut a large galvanized pipe.

It is a tad bit longer coming in at 19″ in length but overall the same size as the previous model. One thing I did enjoy greatly on the newer model is the greatly reduced vibration as it employs a counter-balanced mechanism to smooth out vibration. I’d be lying to you if I said there was no vibration as there is still noticeable vibration but it wasn’t “bone rattling” as the previous model.

Runtime is also said to be improved on the new model so to see if this was true or not I conducted another side by side test. Using an the same M18 XC 3.0ah battery, I tested each saw (old and new model) to see how many cuts they could make into 2×4’s before the battery would discharge completely. The older model got a great 61.5 cuts while the new model got an amazing 110 cuts! I didn’t do the exact math but that’s almost 50% more cuts per charge.

As for features, it uses the tool less Quik-Lok blade clamp for changing blades which is pretty standard on reciprocation saws nowadays. The blade can be positioned facing up or down and it has a pivoting shoe to maintain good contact with the surface as it cuts. Unlike the M18 Fuel model which has all the bells and whistles, this new model doesn’t have an extending shoe or a built in LED light to illuminate dark areas. You have to go Fuel for those features.

So overall the new model is literally bigger, stronger, and better than the outgoing model. I’m starting to wonder if Milwaukee threw a brushless motor in there because the runtime is that good but it deos indeed come with a brushed motor. It won’t outperform the M18 Fuel Sawzall but it’s very impressive nontheless for a brushed 18V reciprocating saw. I haven’t tried too many other brands 18V reciprocating saws at the moment, but I can say the cutting speed is very good and the vibration reduction is great.
